actully i get the folder and files from perticular path but its doesnt returns the value what i want.
im expecting the return value like:-
[{"filename":"19_0_0_0_0_1.jpg","RFI":19},
{"filename":"19_0_0_0_0_2.jpg","RFI":19},
{"filename":"19_20005_1_0_0_1.jpg","RFI":19},
{"filename":"19_20005_1_0_0_2.jpg","RFI":19},
{"filename":"19_20005_1_429_0_1.jpg","RFI":19},
{"filename":"19_20005_1_429_0_2.jpg","RFI":19},
{"filename":"19_20005_1_429_1_1.jpg","RFI":19},
{"filename":"19_20005_1_429_1_2.jpg","RFI":19},
{"filename":"19_20027_1_0_0_1.jpg","RFI":19}]
and its give me like this output :
[{"filename":[{"filename":"19_0_0_0_0_1.jpg","RFI":19},
{"filename":"19_0_0_0_0_2.jpg","RFI":19},
{"filename":"19_20005_1_0_0_1.jpg","RFI":19},
{"filename":"19_20005_1_0_0_2.jpg","RFI":19},
{"filename":"19_20005_1_429_0_1.jpg","RFI":19},
{"filename":"19_20005_1_429_0_2.jpg","RFI":19},
{"filename":"19_20005_1_429_1_1.jpg","RFI":19},
{"filename":"19_20005_1_429_1_2.jpg","RFI":19},
{"filename":"19_20027_1_0_0_1.jpg","RFI":19}],"RFI":19}]
this is my code:
$ldir = "D:\php\EIL_App\RFIImages";
$data = listFolderFiles($ldir,19);
print json_encode($data);
function listFolderFiles($dir,$pRFI)
{
$result = array();
foreach (new DirectoryIterator($dir) as $fileInfo){
if (!$fileInfo->isDot()){
$dataimg = $fileInfo->getFilename();
if($fileInfo->getFilename() == $pRFI){
if ($fileInfo->isDir()){
$dataimg = listFolderFiles($fileInfo->getPathname(),$pRFI);
}
array_push($result,array('filename'=>$dataimg,'RFI'=>$pRFI));
}
}
}
return $result;
}
Please give the suggestion what can i do???
Thanks in advance.
There's no need to complicate things
$prefix = 19;
$dir = "D:\php\EIL_App\RFIImages";
$data = glob("$prefix*.*",19); // it will give you array with all files matching pattern
// then you can do a loop
$arr = [];
foreach ($data as $filename) {
$arr[] = ['filename' => $filename, 'prefix' => $prefix];
}
echo json_encode($arr);
http://php.net/manual/en/function.glob.php
If you want to use iterator then use glob http://php.net/manual/en/globiterator.construct.php
Regarding your code
if ($fileInfo->isDir()) this makes no sense because it will never go to this if. It's because before you check if (!$fileInfo->isDot()){ and dot means either . or .. which applies to directories. If you want to do it recursively then you can use
Edit:
I've noticed you do some recursion if so then probably it'd be better to use ResursiveIterator
function listFolderFiles($dir, $prefix) {
$rii = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($dir));
$files = new RegexIterator($rii, "^$prefix.*", RegexIterator::GET_MATCH); // note prefix cannot have characters that are special to regex or they should be escaped
$arr = array();
foreach($files as $file) {
$arr[] = $file;
}
return $arr;
}

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"
}
}
public function CsvToJson($fileContent){
//Convert CSV To Json and Return
$all_rows = array();

//Extract csv data to array on \n

$header = explode(",",$array[0]);
//Remove Header Row From Main Data Array
array_shift($array);

I have been trying to solve this problem for the better part of two days with no success. I am trying combine/add to a json array that is stored in a .json file on my server using php.
This is a short version of what I'm trying to combine.
box.json:
[{"date":"25.4.2013 10:40:10"},{"comment":"some text"},{"comment":"some more text"}]
posted json:
[{"date":"25.4.2013 10:45:15"},{"comment":"another quote"},{"comment":"quote"}]
This is what I need.
[{"date":"25.4.2013 10:40:10"},{"comment":"some text"},{"comment":"some more text"},
{"date":"25.4.2013 10:45:15"},{"comment":"another quote"},{"comment":"quote"}]
This is what I get. (an array inside an array)
[{"date":"25.4.2013 10:40:10"},{"comment":"some text"},{"comment":"some more text"},
[{"date":"25.4.2013 10:45:15"},{"comment":"another quote"},{"comment":"quote"}]]
This is my code:
<?php
$sentArray = $_POST['json'];
$boxArray = file_get_contents('ajax/box.json');
$sentdata = json_decode($sentArray);
$getdata = json_decode($boxArray);
$sentdata[] = $getdata; /* I also tried array_push($sentdata, $getdata); */
$json = json_encode($sentdata);
$fsize = filesize('ajax/box.json');
if ($fsize <= 5000){
if (json_encode($json) != null) { /* sanity check */
$file = fopen('ajax/box.json' ,'w+');
fwrite($file, $json);
fclose($file);
}else{
/*rest of code*/
}
?>
Please help my sanity is starting to come in to question.
here is your problem
$sentdata[] = $getdata;
use foreach
foreach($getdata as $value)
$sentdata[] = $value;
UPDATE:
but i think you need this for $sentdata not $getdata
foreach($senttdata as $value)
$getdata[] = $value;
then put $getdata to your file.
$box = json_decode(file_get_contents('ajax/box.json'));
$posted = json_decode($_POST['json']);
$merge = array_merge ((array)$box,(array)$posted);
Casting (array) prevent error if $box or $posted become null or false, it will be an empty array
Instead of this:
$sentdata[] = $getdata; /* I also tried array_push($sentdata, $getdata); */
Try:
$combinedData = array_merge($sentData, $getData);
$json = json_encode($combinedData);
By using array_merge you're combining the arrays into one instead of adding one array as a value into the other.
Note that I changed the name of your resulting data - try to avoid variables with the same name and different capitalization, it will make things much easier to understand (for you and for future developers supporting your code).

my Current json code :
{"Results":[{"username":"test","password":"test"},{"username":"test","password":"test"},{"username":"google","password":"test"},{"username":"yahoo","password":"test"},{"username":"hotmail","password":"test"}]}
i want to remove this :
{"username":"google","password":"test"}
from the code using php.
i tried deleting by decoding json to array but cant get it done.
any solution ?
$json_obj = json_decode($json_string);
$unset_queue = array();
foreach ( $json_obj->Results as $i => $item )
{
if ($item->username == "google")
{
$unset_queue[] = $i;
}
}
foreach ( $unset_queue as $index )
{
unset($json_obj->Results[$index]);
}
// rebase the array
$json_obj->Results = array_values($json_obj->Results);
$new_json_string = json_encode($json_obj);
<?php
$JSON = '{"Results":['
. '{"username":"test","password":"test"},'
. '{"username":"test","password":"test"},'
. '{"username":"google","password":"test"},'
. '{"username":"yahoo","password":"test"},'
. '{"username":"hotmail","password":"test"}'
. ']}';
// use json_decode to parse the JSON data in to a PHP object
$jsonInPHP = json_decode($JSON);
// now iterate over the results and remove the one that's google
$results = count($jsonInPHP->Results);
for ($r = 0; $r < $results; $r++){
// look for the entry we are trying to find
if ($jsonInPHP->Results[$r]->username == 'google'
&& $jsonInPHP->Results[$r]->password == 'test'){
// remove the match
unset($jsonInPHP->Results[$r]);
// now we can either break out of the loop (only remove first match)
// or you can use subtract one from $r ($r--;) and keep going and
// find all possible matches--your decision.
break;
}
}
// now that we removed items the keys will be off. let's re-order the keys
// so they're back in-line
$jsonInPHP->Results = array_values($jsonInPHP->Results);
// dump the new JSON data, less google's entry
echo json_encode($jsonInPHP);
Would be how I approach it. I like to avoid foreach(...){} statements when I need to modify the array itself. The above code, by the way, leaves you with:
{
"Results":[
{"username":"test","password":"test"},
{"username":"test","password":"test"},
{"username":"yahoo","password":"test"},
{"username":"hotmail","password":"test"}
]
}
$json = '
{
"Results":[
{"username":"test","password":"test"},
{"username":"test","password":"test"},
{"username":"google","password":"test"},
{"username":"yahoo","password":"test"},
{"username":"hotmail","password":"test"}
]
}';
$arr = json_decode($json, true);
array_filter($arr, function($v) {
return !($v['username'] == 'google' && $v['password'] == 'test');
});
$json = json_encode($arr);
$input='{"Results":[{"username":"test","password":"test"},{"username":"test","password":"test"},{"username":"google","password":"test"},{"username":"yahoo","password":"test"},{"username":"hotmail","password":"test"}]}';
$json = json_decode($input,true);
$match = array('username'=>'google', 'password'=>'test');
unset($json['Results'][array_search($match,$json['Results'])]);
To do it without a foreach but assuming you know the exact values you want to remove
Old question, formatting your JSON differently would help a lot.
Each result entry should have a unique key to identify it.
This makes it easy when needing to remove or update that result.
No reason to iterate over entire JSON this way.
Code would look like this
<?php
$jsonString = '{"Results":{'
.'{"username1":{"username":"google","password":"test1"}}'
.'{"username2":{"username":"yahoo","password":"test2"}}'
.'{"username3":{"username":"msonline","password":"test3"}}'
. '}}';
$jsonInPHP = json_decode($jsonString);
$password = $jsonInPHP["username1"]["pasword"];//Returns test1
$username = $jsonInPHP["username1"]["username"];//Returns google
?>
$myArray=json_decode($theJSONstring);
unset($myArray['Results'][2]);
I want to convert a big yaml file to PHP array source code. I can read in the yaml code and get back a PHP array, but with var_dump($array) I get pseudo code as output. I would like to print the array as valid php code, so I can copy paste it in my project and ditch the yaml.
You're looking for var_export.
You could use var_export, serialize (with unserialize on the reserving end), or even json_encode (and use json_decode on the receiving end). The last one has the advantage of producing output that can be processed by anything that can handle JSON.
Don't know why but I could not find satisfying code anywhere.
Quickly wrote this. Let me know if you find any errors.
function printCode($array, $path=false, $top=true) {
$data = "";
$delimiter = "~~|~~";
$p = null;
if(is_array($array)){
foreach($array as $key => $a){
if(!is_array($a) || empty($a)){
if(is_array($a)){
$data .= $path."['{$key}'] = array();".$delimiter;
} else {
$data .= $path."['{$key}'] = \"".htmlentities(addslashes($a))."\";".$delimiter;
}
} else {
$data .= printCode($a, $path."['{$key}']", false);
}
}
}
if($top){
$return = "";
foreach(explode($delimiter, $data) as $value){
if(!empty($value)){
$return .= '$array'.$value."<br>";
}
};
return $return;
}
return $data;
}
//REQUEST
$x = array('key'=>'value', 'key2'=>array('key3'=>'value2', 'key4'=>'value3', 'key5'=>array()));
echo printCode($x);
//OUTPUT
$array['key'] = 'value';
$array['key2']['key3'] = 'value2';
$array['key2']['key4'] = 'value3';
$array['key2']['key5'] = array();
Hope this helps someone.
An other way to display array as code with indentation.
Tested only with an array who contain string, integer and array.
function bo_print_nice_array($array){
echo '$array=';
bo_print_nice_array_content($array, 1);
echo ';';
}
function bo_print_nice_array_content($array, $deep=1){
$indent = '';
$indent_close = '';
echo "[";
for($i=0; $i<$deep; $i++){
$indent.=' ';
}
for($i=1; $i<$deep; $i++){
