I can easily write to and read from a sub-array in the session array.
$_SESSION['a']['b']['c']['value']=123;
$val=$_SESSION['a']['b']['c']['value'];
Instead of hard coding the "location" where the value is written, I would like it to be definable via a string or some other way. The following will obviously not work, but hopefully will better explain the intent.
$prefix="['a']['b']['c']"; //defined in config page, etc
$_SESSION.$prefix.['value']=123;
$val=$_SESSION.$prefix.['value'];
How can this be accomplished?
PropertyAccess
There is an excellent Symfony component for such tasks, named PropertyAccess. You can use it as follows:
$persons = array('a' => array('b' => 5.7));
$accessor = PropertyAccess::createPropertyAccessor();
echo $accessor->getValue($persons, '[a][b]'); // 5.7
You can install it using Composer as described in docs or fetch directly from GitHub.
Custom solution
This is a complete solution, I'm really impressed that it works... but it works! Check the code below, assert()'s demonstrate the usage:
<?php
function arrayPropertyPathGet(array $arr, $path) {
$parts = explode('.', $path);
$ret = $arr;
foreach($parts as $part) {
$ret = $ret[$part];
}
return $ret;
}
function arrayPropertyPathSet(array &$arr, $path, $value) {
$parts = explode('.', $path);
$tmp = &$arr;
foreach($parts as $part) {
if(!isset($tmp[$part])) { return false; }
$tmp = &$tmp[$part];
}
$tmp = $value;
return true;
}
$test = array('a' => array('b' => 'value'));
assert('value' === arrayPropertyPathGet($test, 'a.b'));
assert(true === arrayPropertyPathSet($test, 'a.b', 'other'));
assert('other' === arrayPropertyPathGet($test, 'a.b'));
Side note
As a theoretical side note (do not use this for anything other than learning purposes) you can experiment with eval(), such as:
eval("$value = $persons['a']['b']");
I faced the same problem a few times ago, and as I didn't find any solution, I made one by myself, if that can help you in anyway (only the interesting part) :
class ArrayAccessor {
private $prefix;
function setPrefix() {
$this->prefix = array();
for ($i = 0; $i < func_num_args(); ++$i) {
$this->prefix[] = func_get_arg($i);
}
}
function getFromPrefix(array $array) {
$tmp_array = $array;
foreach ($this->prefix as $pre) {
if (isset ($tmp_array[$pre])) {
$tmp_array = $tmp_array[$pre];
} else {
return null;
}
}
return $tmp_array;
}
}
$Access = new ArrayAccessor();
$Access->setPrefix('Hi', 'Toto');
$MyTestArray['Hi']['Toto'] = 'Works';
var_dump ($Access->getFromPrefix($MyTestArray));
$Access->setPrefix('Hi');
var_dump ($Access->getFromPrefix($MyTestArray));
$Access->setPrefix('No');
var_dump ($Access->getFromPrefix($MyTestArray));
Result :
string(5) "Works"
array(1) {
["Toto"]=>
string(5) "Works"
}
NULL
I am trying to convert CSV file to JSON using PHP.
Here is my code
<?php
date_default_timezone_set('UTC');
$today = date("n_j"); // Today is 1/23/2015 -> $today = 1_23
$file_name = $today.'.CSV'; // My file name is 1_23.csv
$file_path = 'C:\\Users\\bheng\\Desktop\\qb\\'.$file_name;
$file_handle = fopen($file_path, "r");
$result = array();
if ($file_handle !== FALSE) {
$column_headers = fgetcsv($file_handle);
foreach($column_headers as $header) {
$result[$header] = array();
}
while (($data = fgetcsv($file_handle)) !== FALSE) {
$i = 0;
foreach($result as &$column) {
$column[] = $data[$i++];
}
}
fclose($file_handle);
}
// print_r($result); // I see all data(s) except the header
$json = json_encode($result);
echo $json;
?>
print_r($result); // I see all data(s)
Then I json_encode($result); and tried to display it, but nothing is displaying on the screen at all. All I see is the blank screen, and 0 error message.
Am I doing anything wrong ? Can someone help me ?
Added Result of print_r($result);
Array (
[Inventory] => Array (
[0] => bs-0468R(20ug)
[1] => bs-1338R(1ml)
[2] => bs-1557G(no bsa)
[3] => bs-3295R(no BSA)
[4] => bs-0730R-Cy5"
[5] => bs-3889R-PE-Cy7"
[6] => 11033R
[7] => 1554R-A647
[8] => 4667
[9] => ABIN731018
[10] => Anti-DBNL protein
.... more ....
Try like this:
$file="1_23.csv";
$csv= file_get_contents($file);
$array = array_map("str_getcsv", explode("\n", $csv));
$json = json_encode($array);
print_r($json);
data.csv
Game,Skill
Treasure Hunter,pilipala
Rocket Launcher,bibobibo
Rocket Engine,hehehohoho
To convert with column name, this is how I do it.
csv2json.php
<?php
if (($handle = fopen("data.csv", "r")) !== FALSE) {
$csvs = [];
while(! feof($handle)) {
$csvs[] = fgetcsv($handle);
}
$datas = [];
$column_names = [];
foreach ($csvs[0] as $single_csv) {
$column_names[] = $single_csv;
}
foreach ($csvs as $key => $csv) {
if ($key === 0) {
continue;
}
foreach ($column_names as $column_key => $column_name) {
$datas[$key-1][$column_name] = $csv[$column_key];
}
}
$json = json_encode($datas);
fclose($handle);
print_r($json);
}
The output result
[
{
"Game": "Treasure Hunter",
"Skill": "pilipala"
},
{
"Game": "Rocket Launcher",
"Skill": "bibobibo"
},
{
"Game": "Rocket Engine",
"Skill": "hehehohoho"
}
]
You can try this way too.
<?php
function csvtojson($file,$delimiter)
{
if (($handle = fopen($file, "r")) === false)
{
die("can't open the file.");
}
$csv_headers = fgetcsv($handle, 4000, $delimiter);
$csv_json = array();
while ($row = fgetcsv($handle, 4000, $delimiter))
{
$csv_json[] = array_combine($csv_headers, $row);
}
fclose($handle);
return json_encode($csv_json);
}
$jsonresult = csvtojson("./doc.csv", ",");
echo $jsonresult;
I ran into a similar problem, I ended up using this to recursively convert the data to UTF-8 on an array before encoding to JSON.
function utf8_converter($array)
{
array_walk_recursive($array, function(&$item, $key){
if(!mb_detect_encoding($item, 'utf-8', true)){
$item = utf8_encode($item);
}
});
return $array;
}

This issue is pretty old by now, but hoping this helps someone, as it seemed like the simplest example I found, and I know this is a pretty common thing devs might need to do as a beginner, and lots of answers gloss over the magic.
$file = storage_path('app/public/waitlist_users_test.csv'); //--> laravel helper, but you can use any path here
function csv_to_json($file)
{
// file() loads each row as an array value, then array map uses the 'str_getcsv' callback to
$csv = array_map('str_getcsv', file($file));
// array_walk - "walks" through each item of the array and applies the call back function. the & in "&row" means that alterations to $row actually change the original $csv array, rather than treating it as immutable (*sort of immutable...)
array_walk($csv, function(&$row) use ($csv) {
// array_combine takes the header row ($csv[0]) and uses it as array keys for each column in the row
$row = array_combine($csv[0], $row);
});
array_shift($csv); # removes now very redundant column header --> contains {'col_1':'col_1', 'col_2':'col_2'...}
$json = json_encode($csv);
return $json;
}
There's a lot of magic going on with these functions that accept callback functions, that didn't seem to be explained thoroughly above. I'm self taught and have been programming for years, and find that it's often just glossed over without detailing how callbacks work, so I'll dive in just a little bit for the array_map('str_getcsv', file($file)) function - if you pass a function you've written, or inbuilt php function name as a string, it will take the value of whatever (in this case - array) element is being evaluated by the calling function (in this case array_map), and pass that to the callback function without the need to explicitly pass in a variable - super helpful once you get the hang of it, but I find it's not explained thoroughly very often which leaves beginners to not understand why it works, just that it works.
I've linked most of these above, but here's a little more information:
str-getcsv do? Array Walk Array Map Callables/Callbacks
as #MoonCactus noted, the file() function only loads 1 row at a time which helps save on memory usage for large .csv files.
Also, some other posts reference using explode - why not use explode() instead of str_getcsv() to parse rows? Because explode() would not treat possible enclosured parts of string or escaped characters correctly.
Hope somebody finds this helpful!
If you are converting a dynamic CSV file, you can pass the URL through a parameter (url=http://example.com/some.csv) and it will show you the most up-to-date version:
<?php
// Lets the browser and tools such as Postman know it's JSON
header( "Content-Type: application/json" );
// Get CSV source through the 'url' parameter
if ( isset( $_GET['url'] ) ) {
$csv = explode( "\n", file_get_contents( $_GET['url'] ) );
$index = str_getcsv( array_shift( $csv ) );
$json = array_map(
function ( $e ) use ( $index ) {
return array_combine( $index, str_getcsv( $e ) );
}, $csv
);
}
else {
$json = "Please set the path to your CSV by using the '?url=' query string.";
}
// Output JSON
echo json_encode( $json );
Alternate solution that uses similar method as #Whirlwind's solution but returns a more standard JSON result (with named fields for each object/record):
// takes a string of CSV data and returns a JSON representing an array of objects (one object per row)
function convert_csv_to_json($csv_data){
$flat_array = array_map("str_getcsv", explode("\n", $csv_data));
// take the first array item to use for the final object's property labels
$columns = $flat_array[0];
for ($i=1; $i<count($flat_array)-1; $i++){
foreach ($columns as $column_index => $column){
$obj[$i]->$column = $flat_array[$i][$column_index];
}
}
$json = json_encode($obj);
return $json; // or just return $obj if that's a more useful return value
}
The accepted answer uses file_get_contents() to read the entire file as a string in memory, and then explode() it to make it an array.
But it can be made faster, smaller in memory, and more useful:
function ReadCsv($fn)
{
$lines= file($fn); // read file directly as an array of lines
array_pop($lines); // you can remove the last empty line (if required)
$json= json_encode(array_map("str_getcsv", $lines), JSON_NUMERIC_CHECK);
print_r($json);
}
Nb: I used JSON_NUMERIC_CHECK here to avoid numbers being double quoted into strings. It also reduces the output size and it usually helps javascript on the other side (e.g. to compute or plot the data). Beware of phone numbers though!
I liked #ian-d-miller's solution for converting the data into a key / value style format, but I kept running into issues with his code.
Here's what worked for me:
function convert_CSV_to_JSON($csv_data){
// convert csv data to an array
$data = array_map("str_getcsv", explode("\n", $csv_data));
// use the first row as column headers
$columns = $data[0];
// create array to hold our converted data
$json = [];
// iterate through each row in the data
foreach ($data as $row_index => $row_data) {
// skip the first row, since it's the headers
if($row_index === 0) continue;
// make sure we establish each new row as an array
$json[$row_index] = [];
// iterate through each column in the row
foreach ($row_data as $column_index => $column_value) {
// get the key for each entry
$label = $columns[$column_index];
// add this column's value to this row's index / column's key
$json[$row_index][$label] = $column_value;
}
}
// bam
return $json;
}
Usage:
// as is
$json = convert_CSV_to_JSON($csv);
// encoded
$json = json_encode($json);
Something that i've made for myself and may be useful for others :)
This will convert CSV into JSON array with objects (key => value pair).
function csv2json($a, $e = true) {
$b = ["\r\n","\r","\n",];
foreach ($b as $c => $d) {
$a = explode($d, $a);
$a = isset($b[$c + 1]) ? implode($b[$c + 1], $a) : implode(PHP_EOL, $a);
}
// Convert to CSV
$a = array_map("str_getcsv", explode(PHP_EOL, $a));
// Get the first part of the array as the keys
$a = [
"keys" => array_shift($a),
"rows" => $a,
"row" => null,
];
// Define JSON
$b = [];
foreach ($a["rows"] as $a["row"]) {
$a["row"] = [ "csv" => $a["row"], "json" => (object)[], ];
for ($c = 0; $c < count($a["row"]["csv"]); $c++) {
$a["row"]["csv"][$c] = [#json_decode($a["row"]["csv"][$c]),$a["row"]["csv"][$c]];
// Switch from string to booleans, numbers and others
$a["row"]["csv"][$c] = isset($a["row"]["csv"][$c][0]) ? $a["row"]["csv"][$c][0] : $a["row"]["csv"][$c][1];
// Push it back
$a["row"]["json"]->{$a["keys"][$c]} = $a["row"]["csv"][$c];
}
$a["row"] = $a["row"]["json"];
$b[] = $a["row"];
unset($a["row"]);
}
// $e will be "return"
$e = $e ? json_encode($b) : $b;
// Unset useless variables
unset($a, $b, $c, $d);
return $e;
}
How to use?
If you want to return the JSON as a string, Leave it as default.
If you want to return the JSON as an object / array, set the second parameter to false.
Examples:
$csv = "name,age,gender
John Doe,35,male
Jane Doe,32,female";
echo csv2json($csv, true); // Or without the second parameter, just csv2json($csv)
The example above (^) will return a JSON stringified, Like this:
[{"name":"John Doe","age":35,"gender":"male"},{"name":"Jane Doe","age":32,"gender":"female"}]
and the example below:
var_dump(csv2json($csv, false));
will return a JSON array with these objects:
array(2) {
[0]=>
object(stdClass)#1 (3) {
["name"]=>
string(8) "John Doe"
["age"]=>
int(35)
["gender"]=>
string(4) "male"
}
[1]=>
object(stdClass)#2 (3) {
["name"]=>
string(8) "Jane Doe"
["age"]=>
int(32)
["gender"]=>
string(6) "female"
}
}

I would parse the following string:
$str = 'ProceduresCustomer.tipi_id=10&ProceduresCustomer.id=1';
parse_str($str,$f);
I wish that $f be parsed into:
array(
'ProceduresCustomer.tipi_id' => '10',
'ProceduresCustomer.id' => '1'
)
Actually, the parse_str returns
array(
'ProceduresCustomer_tipi_id' => '10',
'ProceduresCustomer_id' => '1'
)
Beside writing my own function, does anybody know if there is a php function for that?
From the PHP Manual:
Dots and spaces in variable names are converted to underscores. For example <input name="a.b" /> becomes $_REQUEST["a_b"].
So, it is not possible. parse_str() will convert all periods to underscores. If you really can't avoid using periods in your query variable names, you will have to write custom function to achieve this.
The following function (taken from this answer) converts the names of each key-value pair in the query string to their corresponding hexadecimal form and then does a parse_str() on it. Then, they're reverted back to their original form. This way, the periods aren't touched:
function parse_qs($data)
{
$data = preg_replace_callback('/(?:^|(?<=&))[^=[]+/', function($match) {
return bin2hex(urldecode($match[0]));
}, $data);
parse_str($data, $values);
return array_combine(array_map('hex2bin', array_keys($values)), $values);
}
Example usage:
$data = parse_qs($_SERVER['QUERY_STRING']);
Quick 'n' dirty.
$str = "ProceduresCustomer.tipi_id=10&ProceduresCustomer.id=1";
function my_func($str){
$expl = explode("&", $str);
foreach($expl as $r){
$tmp = explode("=", $r);
$out[$tmp[0]] = $tmp[1];
}
return $out;
}
var_dump(my_func($str));
array(2) {
["ProceduresCustomer.tipi_id"]=> string(2) "10"
["ProceduresCustomer.id"]=>string(1) "1"
}
This quick-made function attempts to properly parse the query string and returns an array.
The second (optional) parameter $break_dots tells the parser to create a sub-array when encountering a dot (this goes beyond the question, but I included it anyway).
/**

I tried to correctly handle multi-level keys. The code is a bit hacky, but it should work. I tried to comment the code, comment if you have any question.
Test case:
var_dump(decode_qstr("ProceduresCustomer.tipi_id=10&ProceduresCustomer.id=1"));
// array(2) {
// ["ProceduresCustomer.tipi_id"]=>
// string(2) "10"
// ["ProceduresCustomer.id"]=>
// string(1) "1"
// }
var_dump(decode_qstr("ProceduresCustomer.tipi_id=10&ProceduresCustomer.id=1", true));
// array(1) {
// ["ProceduresCustomer"]=>
// array(2) {
// ["tipi_id"]=>
// string(2) "10"
// ["id"]=>
// string(1) "1"
// }
// }
I would like to add my solution as well, because I had trouble finding one that did all I needed and would handle all circumstances. I tested it quite thoroughly. It keeps dots and spaces and unmatched square brackets (normally changed to underscores), plus it handles arrays in the input well. Tested in PHP 8.0.0 and 8.0.14.
const periodPlaceholder = 'QQleQPunT';
const spacePlaceholder = 'QQleQSpaTIE';
function parse_str_clean($querystr): array {
// without the converting of spaces and dots etc to underscores.
$qquerystr = str_ireplace(['.','%2E','+',' ','%20'], [periodPlaceholder,periodPlaceholder,spacePlaceholder,spacePlaceholder,spacePlaceholder], $querystr);
$arr = null ; parse_str($qquerystr, $arr);
sanitizeArr($arr, $querystr);
return $arr;
}
function sanitizeArr(&$arr, $querystr) {
foreach($arr as $key=>$val) {
// restore values to original
if ( is_string($val)) {
$newval = str_replace([periodPlaceholder,spacePlaceholder], ["."," "], $val);
if ( $val != $newval) $arr[$key]=$newval;
}
}
unset($val);
foreach($arr as $key=>$val) {
$newkey = str_replace([periodPlaceholder,spacePlaceholder], ["."," "], $key);
if ( str_contains($newkey, '_') ) {
// periode of space or [ or ] converted to _. Restore with querystring
$regex = '/&('.str_replace('_', '[ \.\[\]]', preg_quote($newkey, '/')).')=/';
$matches = null ;
if ( preg_match_all($regex, "&".urldecode($querystr), $matches) ) {
if ( count(array_unique($matches[1])) === 1 && $key != $matches[1][0] ) {
$newkey = $matches[1][0] ;
}
}
}
if ( $newkey != $key ) $arr = array_replace_key($arr,$key, $newkey);
if ( is_array($val)) {
sanitizeArr($arr[$newkey], $querystr);
}
}
}
function array_replace_key($array, $oldKey, $newKey): array {
// preserves order of the array
if( ! array_key_exists( $oldKey, $array ) ) return $array;
$keys = array_keys( $array );
$keys[ array_search( $oldKey, $keys ) ] = $newKey;
return array_combine( $keys, $array );
}
First replaces spaces and . by placeholders in querystring before coding before parsing, later undoes that within the array keys and values. This way we can use the normal parse_str.
Unmatched [ and ] are also replaced by underscores by parse_str, but these cannot be reliably replaced by a placeholder. And we definitely don't want to replace matched []. Hence we don't replace [ and ], en let them be replaced by underscores by parse_str. Then we restore the _ in the resulting keys and seeing in the original querystring if there was a [ or ] there.
Known bug: keys 'something]something' and almost identical 'something[something' may be confused. It's occurrence will be zero, so I left it.
Test:
var_dump(parse_str_clean("code.1=printr%28hahaha&code 1=448044&test.mijn%5B%5D%5B2%5D=test%20Roemer&test%20mijn%5B=test%202e%20Roemer"));
yields correctly
array(4) {
["code.1"]=>
string(13) "printr(hahaha"
["code 1"]=>
string(6) "448044"
["test.mijn"]=>
array(1) {
[0]=>
array(1) {
[2]=>
string(11) "test Roemer"
}
}
["test[mijn"]=>
string(14) "test 2e Roemer"
}
whereas the original parse_str only yields, with the same string:
array(2) {
["code_1"]=>
string(6) "448044"
["test_mijn"]=>
string(14) "test 2e Roemer"
}
I am using PL/pgsql RETURNS TABLE to get the below output using pg_fetch_all in PHP
array(4) {
[0]=> array(1)
{ ["not_actual_values"]=> string(88) "("var1","var2",var3,var4,date1,int,int,int,var5,int,int,int,int)" }
[1]=> array(1)
{ ["not_actual_values"]=> string(89) "("var1","var2",var3,var4,date1,int,int,int,var5,int,int,int,int)" }
[2]=> array(1)
{ ["not_actual_values"]=> string(88) "("var1","var2",var3,var4,date1,int,int,int,var5,int,int,int,int)" }
[3]=> array(1)
{ ["not_actual_values"]=> string(89) "("var1","var2",var3,var4,date1,int,int,int,var5,int,int,int,int)" }
}
I am unable to use the above output in HTML. I tried using php explode but it didnt work I got zero array. Also, What confuses me I am getting quotes in first two variable and not in others.
Update
I used below function but I got zero array
function pgArrayToPhp($text) {
if(is_null($text)) {
return array();
} else if(is_string($text) && $text != '{}') {
$text = substr($text, 1, -1);// Removes starting "{" and ending "}"
if(substr($text, 0, 1) == '"') {
$text = substr($text, 1);
}
if(substr($text, -1, 1) == '"') {
$text = substr($text, 0, -1);
}
// If double quotes are present, we know we're working with a string.
if(strstr($text, '"')) { // Assuming string array.
$values = explode('","', $text);
} else { // Assuming Integer array.
$values = explode(',', $text);
}
$fixed_values = array();
foreach($values as $value) {
$value = str_replace('\\"', '"', $value);
$fixed_values[] = $value;
}
return $fixed_values;
} else {
return array();
}
}
How can i do this ?
Your inner values are arrays, not strings, you need to take that into account:
function pgArraytoPhp($array) {
foreach ($array as $row) { // $row is an inner array here!
actuallyDoParsing($row[0]); // Parse row's first element,
// which will be the string you want.
}
}
Depending on what you need, you'll return the accumulated result of all of those actuallyDoParsing() calls.
This is the answer that I have come up with. Though it is not neat but it seems to be working as expected now
$fetch=pg_fetch_all($query); //fetching data from postgresql
$count=count($fetch);
for ($j=0;$j<$count;$j++) {
$a = $fetch[$j]['not_actual_values'];
$b = array(explode("," , $a));
$count2=count($b[0]);
foreach ($b as $f) { echo '<tr>';
for ($i=0;$i<$count2;$i++){
echo '<td><input type="text" readonly value='.$f[$i].'>';
} } }
But now the problem is raw data contains noise as in "(" so that is spoiling the output.
Thank you all for your efforts.
I am trying to create a new instance of Imagick:
$original = new Imagick($array);
I do this in two different instances. One way always works, and the other way always fails, but they use the same exact array (the array isn't always identical, but for ease of explanation, I am showing an example that happens to use identical arrays). Here is a var_dump of each array:
Working Array:
array(3) { [0]=> string(20) "image_files/bbb0.jpg" [1]=> string(20) "image_files/bbb1.jpg" [2]=> string(20) "image_files/bbb2.jpg" }
Failing Array:
array(3) { [0]=> string(20) "image_files/bbb0.jpg" [1]=> string(20) "image_files/bbb1.jpg" [2]=> string(20) "image_files/bbb2.jpg" }
As you can see, they are identical, so why is my PHP dying at
$new = new Imagick($array);
Is there something different about the second array that I'm not seeing?
EDIT: Here's the code that constructs the array that is failing:
$n = $_GET["n"];
$city = preg_replace("/[0-9]/", "", $n);
$num = preg_replace("/".$city."/","",$n);
// create an array to hold directory list
$results = array();
// create a handler for the directory
$directory = '../image_files';
$handler = opendir($directory);
while ($file = readdir($handler)) {
// if file isn't this directory or its parent, add it to the results
if ($file != "." && $file != "..") {
// check with regex that the file format is what we're expecting and not something else
if (preg_match("/^".$city."[1-9][0-9]\.jpg$/i",$file)) {
if (preg_match("/^".$city.$num."\.jpg$/i",$file)) {
unlink("../image_files/".$file);
} else {
$results[] = "../image_files/" . $file;
}
} else if (preg_match("/^".$city."[0-9]\.jpg$/i",$file)) {
if (preg_match("/^".$city.$num."\.jpg$/i",$file)) {
unlink("../image_files/".$file);
} else {
$results[] = "../image_files/" . $file;
}
}
}
}
sort($results);
$i = 0;
$newResults = array();
foreach( $results as $key => $value ) {
$old = $value;
//echo "old: " . $old . " ";
if (preg_match("/[1-9][0-9]/",$value)) {
$newstr = preg_replace("/[1-9][0-9]/", $i."temp", $value);
} else if (preg_match("/[0-9]/",$value)) {
$newstr = preg_replace("/[0-9]/", $i."temp", $value);
}
$newResults[] = $newstr;
//echo "new: " . $newstr . "<br>";
rename($old,$newstr);
$i++;
}
// create an array to hold directory list
$results = array();
// create a handler for the directory
$directory = '../image_files';
$handler = opendir($directory);
while ($file = readdir($handler)) {
// if file isn't this directory or its parent, add it to the results
if ($file != "." && $file != "..") {
$old = $file;
$new = preg_replace("/temp/", "", $file);
rename("../image_files/".$old,"../image_files/".$new);
}
}
$finalResults = array();
foreach( $newResults as $key => $value ) {
$newstr = str_replace("../", "", $value);
$newstr = str_replace("temp","",$newstr);
$finalResults[] = $newstr;
}
sort($finalResults);
createMontage($finalResults,"-a",$city);
The problem was in the directory structure of the PHP files.
The "working array" is being created from the base directory.
The "failing array" is being created from a directory named actions.
It doesn't matter where the script you're running exists, it matters what loaded that script (ie. Was it loaded from the root dir via include or require? Or was is called directly www.example.com/scripts/script.php). This will determine how to construct your path to other files.
