PHP Change end of value? - php

I am having some trouble with php.
I have a variable $image that contains a url, like
$image='http://example.com/image.jpg'
I am trying to change the name of the image to this, meanwhile not changing the url:
$image='http://example.com/image01.jpg'
$image='http://example.com/image02.jpg'
$image='http://example.com/image03.jpg'
and so on..
Any idea how I can do this?
Or should I use some Javascript?

Code:
$link = 'http://example.com/image.jpg';
for($i=1;$i<=3;$i++) {
$array[] = str_replace('.jpg',sprintf("%02d",$i).'.jpg',$link);
}
print_r($array);
Result:
Array
(
[0] => http://example.com/image01.jpg
[1] => http://example.com/image02.jpg
[2] => http://example.com/image03.jpg
)
EDIT
This works regardless of extension:
$link = 'http://example.com/image.png';
for($i=1;$i<=3;$i++) {
$array[] = substr_replace($link,sprintf("%02d",$i),strripos($link,'.'),0);
}
print_r($array);
Result:
Array
(
[0] => http://example.com/image01.png
[1] => http://example.com/image02.png
[2] => http://example.com/image03.png
)

This will add numbering before last . whichever is the $image file extension
$image = 'http://example.com/image.jpg';
$pos = strripos($image, '.');
$head = substr($image, 0, $pos);
$tail = substr($image, $pos);
for($i=1; $i<=3; $i++) {
$image = $head.sprintf("%02d", $i).$tail;
}

Reading values from a file which contains associative array PHP

I need to read the content of a file called orders.log with PHP and use the variables. The log file is stored like this:
Array
(
[time] => 2099-99-99 00:00:00
[gateway] => Paypal
[gatewayOK] => Yes
[gatewayTransactionId] => XXXXXXX
[POST] => Array
(
[mc_gross] => 9.99
[protection_eligibility] => Eligible
[address_status] => confirmed
[payer_id] => XXXXX
[address_street] => XXXXX
[payment_date] => 00:00:00 Nov 11, 2018 PDT
[payment_status] => Completed
[charset] => windows-1252
)
)
I have tried reading it like this:
<?php
$orders=file_get_contents("orders.log");
echo $orders['time'];
echo $myarray[0]['gateway'];
echo $myarray[1]['mc_gross'];
?>
But the result does not work like intended. It throws "A" and "r" . Any help would be appreciated.
This assumes that each entry is 20 lines long, it reads in the log file and the splits it into 20 segments using array_chunk().
It then processes each segment, first splitting the lines by the => using explode() and adding the values to an associative array with the left hand side as the key. You can then use the key to access each value.
$input = file("log.txt", FILE_IGNORE_NEW_LINES);
$orders = array_chunk($input, 20);
foreach ( $orders as $order ) {
$split = [];
foreach ( $order as $line ) {
$info = explode("=>", $line);
if ( count($info) == 2){
$split[trim($info[0]," \t[]")] = trim ($info[1]);
}
}
echo "gateway-".$split['gateway'].PHP_EOL;
echo "mc_gross-".$split['mc_gross'].PHP_EOL;
}
If you wanted a list of all orders...
$input = file("log.txt", FILE_IGNORE_NEW_LINES);
$orders = array_chunk($input, 20);
$orderList = [];
foreach ( $orders as $order ) {
$split = [];
foreach ( $order as $line ) {
$info = explode("=>", $line);
if ( count($info) == 2){
$split[trim($info[0]," \t[]")] = trim ($info[1]);
}
}
$orderList[] = $split;
}
echo "gateway-".$orderList[0]['gateway'].PHP_EOL;
echo "mc_gross-".$orderList[0]['mc_gross'].PHP_EOL;
A third way which doesn't rely on the data being all the same format, this reads on a line by line basis and tries to work out the end of an element itself (just a line containing ))...
$fp = fopen("log.txt", "r");
$orderList = [];
$order = [];
while ( $line = fgets($fp)) {
// Remove extra data after content
$line = rtrim($line);
// If end of order (a line just starting with a ')')
if ( $line == ')' ) {
// Convert order into associative array
$split = [];
foreach ( $order as $line ) {
$info = explode("=>", $line);
if ( count($info) == 2){
$split[trim($info[0]," \t[]")] = trim ($info[1]);
}
}
// Add data to order list
$orderList[] = $split;
$order = [];
}
else {
// Add line to existing data
$order[] = $line;
}
}
print_r($orderList);
fclose($fp);

PHP group certain results from foreach on array into another array

I have an array that looks something like this:
$array = array( [0] => FILE-F01-E1-S01.pdf
[1] => FILE-F01-E1-S02.pdf
[2] => FILE-F01-E1-S03.pdf
[3] => FILE-F01-E1-S04.pdf
[4] => FILE-F01-E1-S05.pdf
[5] => FILE-F02-E1-S01.pdf
[6] => FILE-F02-E1-S02.pdf
[7] => FILE-F02-E1-S03.pdf );
Basically, I need to look at the first file and then get all the other files that have the same beginning ('FILE-F01-E1', for example) and put them into an array. I don't need to do anything with the other ones at this point.
I've been trying to use a foreach loop finding the previous value to do this, but am not having any luck.
Like this:
$previousFile = null;
foreach($array as $file)
{
if(substr_replace($previousFile, "", -8) == substr_replace($file, "", -8))
{
$secondArray[] = $file;
}
$previousFile = $file;
}
So then $secondArray would look like this:
Array ( [0] => FILE-F01-E1-S01.pdf [1] => FILE-F01-E1-S02.pdf
[2] => FILE-F01-E1-S03.pdf [3] => FILE-F01-E1-S04.pdf
[4] => FILE-F01-E1-S05.pdf)
As my result.
Thank you!
You can use array_filter combined with strpos:
$result = array_filter($array, function($filename) {
return strpos($filename, 'FILE-F01-E1') === 0;
});
Are you sure this will be the naming format? That is crucial information to have to construct a regexp or something to check for being a substring of the following strings.
If we can assume this and that the "base" name is always at index 0 then you could do something like.
<?php
$myArr = [
'FILE-F01-E1-S01.pdf',
'FILE-F01-E1-S02.pdf',
'FILE-F01-E1-S03.pdf',
'FILE-F01-E1-S04.pdf',
'FILE-F01-E1-S05.pdf',
'FILE-F02-E1-S01.pdf',
'FILE-F02-E1-S02.pdf',
'FILE-F02-E1-S03.pdf'
];
$baseName = '';
$allSimilarNames = [];
foreach($myArr as $index => &$name) {
if($index == 0) {
$baseName = substr($name, 0, strrpos($name, '-'));
$allSimilarNames[] = $name;
}
else {
if(strpos($name, $baseName) === 0) {
$allSimilarNames[] = $name;
}
}
}
var_dump($allSimilarNames);
This will
Check at index one to get the base name to compare against
Loop all items in the array and match all items, no matter where in the array they are, that are similar according to your naming convention
So if you next time have an array that is
$myArr = [
'FILE-F02-E1-S01.pdf',
'FILE-F01-E1-S01.pdf',
'FILE-F01-E1-S02.pdf',
'FILE-F01-E1-S03.pdf',
'FILE-F01-E1-S04.pdf',
'FILE-F01-E1-S05.pdf',
'FILE-F02-E1-S02.pdf',
'FILE-F02-E1-S03.pdf'
];
this will return all the items that match FILE-F02-E1*.
You could also make a small function of it for easier use and not have to rely on the element at index 0 having to be the "base" name.
<?php
function findMatches($baseName, &$names) {
$matches = [];
$baseName = substr($baseName, 0, strrpos($baseName, '-'));
foreach($names as &$name) {
if(strpos($name, $baseName) === 0) {
$matches[] = $name;
}
}
return $matches;
}
$myArr = [
'FILE-F01-E1-S01.pdf',
'FILE-F01-E1-S02.pdf',
'FILE-F01-E1-S03.pdf',
'FILE-F01-E1-S04.pdf',
'FILE-F01-E1-S05.pdf',
'FILE-F02-E1-S01.pdf',
'FILE-F02-E1-S02.pdf',
'FILE-F02-E1-S03.pdf'
];
$allSimilarNames = findMatches('FILE-F01-E1-S01.pdf', $myArr);
var_dump($allSimilarNames);
Run a simple foreach with strpos() which looks for an occurrence of a string within a string.
$results = array();
foreach($array as $item){
if (strpos($item, 'FILE-F01-E1') === 0) {
array_push($results, $item);
}
}
You could get the first item from the array and use explode and implode to get the part from the filename without the last hyphen and the content after that.
Then use array_filter and use substr using 0 as the start position and the length of the $fileBeginning as the length to check if the string starts with FILE-F01-E1:
$array = [
'FILE-F01-E1-S01.pdf',
'FILE-F01-E1-S02.pdf',
'FILE-F01-E1-S03.pdf',
'FILE-F01-E1-S04.pdf',
'FILE-F01-E1-S05.pdf',
'FILE-F02-E1-S01.pdf',
'FILE-F02-E1-S02.pdf',
'FILE-F02-E1-S03.pdf',
"TESTFILE-F01-E1-S03.pdf"
];
$parts = explode('-', $array[0]);
array_pop($parts);
$fileBeginning = implode('-', $parts);
$secondArray = array_filter($array, function ($x) use ($fileBeginning) {
return substr($x, 0, strlen($fileBeginning)) === $fileBeginning;
});
print_r($secondArray);
Result
Array
(
[0] => FILE-F01-E1-S01.pdf
[1] => FILE-F01-E1-S02.pdf
[2] => FILE-F01-E1-S03.pdf
[3] => FILE-F01-E1-S04.pdf
[4] => FILE-F01-E1-S05.pdf

PHP Result Data Spilt / Explode with assign value

I am new to PHP and working to get some results but failing to achieve my target. I have text file which contains data like this,
APAC|AU|enable|SYD1925|8|20150929|WORKING
APAC|AU|disable|ADL7235|3|20120123|RESIGNED
APAC|NZ|disable|NZ1356|6|20110123|RESIGNED
APAC|NZ|enable|NZ1356|3|20130123|WORKING
I am trying to search "AU" && "enable" for this text, line by line and I am a bit successful in it. Here is my Code example;
public function scan1()
{
$file = FCPATH.'uploads/example.txt';
// the following line prevents the browser from parsing this as HTML.
header('Content-Type: text/plain');
$search1 = "AU";
$search2 = "enable";
$lines = file($file);
foreach($lines as $line)
{
if(stristr($line,$search1) && stristr($line,$search2))
echo $line;
}
}
Now, I am trying to explode/split output data and assign variable / array to save in database but I am failing to do so, can someone please help or give me some direction to achieve this. Thank you
Please show us your_table scheme.
If '$db' is a handle of the db connection :
foreach($lines as $line)
{
if(stristr($line,$search1) && stristr($line,$search2))
{
$arr = explode("|", $line);
$query = "INSERT INTO your_table VALUES ('".$arr[0]."', '".$arr[1]."', '".$arr[2]."', '".$arr[3]."', '".$arr[4]."', '".$arr[5]."')";
$db->query($query);
}
}
First, obtain the file contents with file_get_contents:
$str = file_get_contents(FCPATH.'uploads/example.txt');
Then, use the regex (preg_match_all) to find all portion of text you're looking for:
preg_match_all("/APAC\\|(\w{2}\\|\w+)/", $str, $matches);
Then adapt the array so the 'AU' and 'enabled' are separated (array_map, explode):
$matches = array_map(function ($v) { return explode('|', $v); }, $matches[1]);
So, print_r($matches); returns:
Array
(
[0] => Array
(
[0] => AU
[1] => enable
)
[1] => Array
(
[0] => AU
[1] => disable
)
[2] => Array
(
[0] => NZ
[1] => disable
)
[3] => Array
(
[0] => NZ
[1] => enable
)
)
Finally, the foreach loop:
foreach($matches as $k => $kv)
{
$search1 = $kv[0]; // AU
$search2 = $kv[1]; // enabled
}
This works as expected:
public function scan1()
{
$file = FCPATH.'uploads/example.txt';
// the following line prevents the browser from parsing this as HTML.
header('Content-Type: text/plain');
$search1 = "AU";
$search2 = "enable";
$lines = file($file);
foreach($lines as $line)
{
if(strpos($line,$search1) !== false && strpos($line,$search2) !== false)
echo $line;
}
}
using strpos function for detection.

Parsing complex URLs

I try to parse a list of url strings, after two hours of work I don't reach any result, the list of url strings look like this:
$url_list = array(
'http://google.com',
'http://localhost:8080/test/project/',
'http://mail.yahoo.com',
'http://www.bing.com',
'http://www.phpromania.net/forum/viewtopic.php?f=24&t=7549',
'https://prodgame10.alliances.commandandconquer.com/12/index.aspx',
'https://prodgame10.alliances.commandandconquer.ro/12/index.aspx',
);
Output should be:
Array
(
[0] => .google.com
[1] => .localhost
[2] => .yahoo.com
[3] => .bing.com
[4] => .phpromania.net
[5] => .commandandconquer.com
)
The first thing what induce me in the error zone is more than 2 dots in the url.
Any algorithm example?
This is what I try:
$url_list = array(
'http://google.com',
'http://localhost:8080/test/project/',
'http://mail.yahoo.com',
'http://www.bing.com',
'http://www.phpromania.net/forum/viewtopic.php?f=24&t=27549',
'https://prodgame10.alliances.commandandconquer.com/12/index.aspx',
);
function size($list)
{
$i=0;
while($list[++$i]!=NULL);
return $i;
}
function url_Host($list)
{
$listSize = size($list)-1;
do
{
$strSize = size($list[$listSize]);
$points = 0;
$dpoints = 0;
$tmpString = '';
do
{
$currentChar = $list[$listSize][$strSize];
if(ord('.')==ord($currentChar))
{
$tmpString .= '.';
$points++;
}
else if(ord(':')==ord($currentChar))
{
$tmpString .= ':';
$dpoints++;
}
}while($list[$listSize][--$strSize]!=NULL);
print $tmpString;
$strSize = size($list[$listSize]);
$tmpString = '';
do
{
$slice = false;
$currentChar = $list[$listSize][$strSize];
if($dpoints > 2)
{
if(ord('\\')==ord($curentChar)) $slice = true;
$tmpString .= '';
}
}while($list[$listSize][--$strSize]!=NULL);
print $tmpString."<br />";
}while($list[--$listSize]);
}
url_Host($url_list);
You can use the built-in function parse_url() as follows:
function getDomain($url)
{
$domain = implode('.', array_slice(explode('.', parse_url($url, PHP_URL_HOST)), -2));
return $domain;
}
Test cases:
foreach ($url_list as $url) {
$result[] = getDomain($url);
}
Output:
Array
(
[0] => google.com
[1] => localhost
[2] => yahoo.com
[3] => bing.com
[4] => phpromania.net
[5] => commandandconquer.com
[6] => commandandconquer.ro
)
As for the dots, you can manually prepend them to string, like so:
$result[] = "." . getDomain($url);
I'm not sure why you need to do this, but this should work.
Demo!
Look at parse_url. For example:
$url = 'http://www.phpromania.net/forum/viewtopic.php?f=24&t=7549';
$host = parse_url($url, PHP_URL_HOST);
First the result for localhost is no sense, but try this:
$result =array();
foreach($url_list as $u){
$arr = explode('//',$u);
$arr2 = explode('.', $arr[1]);
if($arr2[0] == 'www')
array_push($result, $arr2[1]);
else
array_push($result, $arr2[0]);
}
We can also use array_map() with an arrow function to simplify the code.
I'm refactoring #Alessandro Minoccheri's code here.
$domains = array_map(fn($url) => implode('.', array_slice(explode('.', parse_url($url, PHP_URL_HOST)), -2)),$urls);
var_dump($domains);

Query string like parameters regex

From a text like:
category=[123,456,789], subcategories, id=579, not_in_category=[111,333]
I need a regex to get something like:
$params[category][0] = 123;
$params[category][1] = 456;
$params[category][2] = 789;
$params[subcategories] = ; // I just need to know that this exists
$params[id] = 579;
$params[not_category][0] = 111;
$params[not_category][1] = 333;
Thanks everyone for the help.
PS
As you suggested, I clarify that the structure and the number of items may change.
Basically the structure is:
key=value, key=value, key=value, ...
where value can be:
a single value (e.g. category=123 or postID=123 or mykey=myvalue, ...)
an "array" (e.g. category=[123,456,789])
a "boolean" where the TRUE value is an assumption from the fact that "key" exists in the array (e.g. subcategories)
This method should be flexible enough:
$str = 'category=[123,456,789], subcategories, id=579, not_in_category=[111,333]';
$str = preg_replace('#,([^0-9 ])#',', $1',$str); //fix for string format with no spaces (count=10,paginate,body_length=300)
preg_match_all('#(.+?)(,[^0-9]|$)#',$str,$sections); //get each section
$params = array();
foreach($sections[1] as $param)
{
list($key,$val) = explode('=',$param); //Put either side of the "=" into variables $key and $val
if(!is_null($val) && preg_match('#\[([0-9,]+)\]#',$val,$match)>0)
{
$val = explode(',',$match[1]); //turn the comma separated numbers into an array
}
$params[$key] = is_null($val) ? '' : $val;//Use blank string instead of NULL
}
echo '<pre>'.print_r($params,true).'</pre>';
var_dump(isset($params['subcategories']));
Output:
Array
(
[category] => Array
(
[0] => 123
[1] => 456
[2] => 789
)
[subcategories] =>
[id] => 579
[not_in_category] => Array
(
[0] => 111
[1] => 333
)
)
bool(true)
Alternate (no string manipulation before process):
$str = 'count=10,paginate,body_length=300,rawr=[1,2,3]';
preg_match_all('#(.+?)(,([^0-9,])|$)#',$str,$sections); //get each section
$params = array();
foreach($sections[1] as $k => $param)
{
list($key,$val) = explode('=',$param); //Put either side of the "=" into variables $key and $val
$key = isset($sections[3][$k-1]) ? trim($sections[3][$k-1]).$key : $key; //Fetch first character stolen by previous match
if(!is_null($val) && preg_match('#\[([0-9,]+)\]#',$val,$match)>0)
{
$val = explode(',',$match[1]); //turn the comma separated numbers into an array
}
$params[$key] = is_null($val) ? '' : $val;//Use blank string instead of NULL
}
echo '<pre>'.print_r($params,true).'</pre>';
Another alternate: full re-format of string before process for safety
$str = 'count=10,paginate,body_length=300,rawr=[1, 2,3] , name = mike';
$str = preg_replace(array('#\s+#','#,([^0-9 ])#'),array('',', $1'),$str); //fix for varying string formats
preg_match_all('#(.+?)(,[^0-9]|$)#',$str,$sections); //get each section
$params = array();
foreach($sections[1] as $param)
{
list($key,$val) = explode('=',$param); //Put either side of the "=" into variables $key and $val
if(!is_null($val) && preg_match('#\[([0-9,]+)\]#',$val,$match)>0)
{
$val = explode(',',$match[1]); //turn the comma separated numbers into an array
}
$params[$key] = is_null($val) ? '' : $val;//Use blank string instead of NULL
}
echo '<pre>'.print_r($params,true).'</pre>';
You can use JSON also, it's native in PHP : http://php.net/manual/fr/ref.json.php
It will be more easy ;)
<?php
$subject = "category=[123,456,789], subcategories, id=579, not_in_category=[111,333]";
$pattern = '/category=\[(.*?)\,(.*?)\,(.*?)\]\,\s(subcategories),\sid=(.*?)\,\snot_in_category=\[(.*?)\,(.*?)\]/';
preg_match($pattern, $subject, $matches, PREG_OFFSET_CAPTURE, 3);
print_r($matches);
?>
I think this will get you the matches out... didn't actually test it but it might be a good starting point.
Then you just need to push the matches to the correct place in the array you need. Also test if the subcategories string exists with strcmp or something...
Also, notice that I assumed your subject string has that fixe dtype of structure... if it is changing often, you'll need much more than this...
$str = 'category=[123,456,789], subcategories, id=579, not_in_category=[111,333]';
$main_arr = preg_split('/(,\s)+/', $str);
$params = array();
foreach( $main_arr as $value) {
$pos = strpos($value, '=');
if($pos === false) {
$params[$value] = null;
} else {
$index_part = substr($value, 0, $pos);
$value_part = substr($value, $pos+1, strlen($value));
$match = preg_match('/\[(.*?)\]/', $value_part,$xarr);
if($match) {
$inner_arr = preg_split('/(,)+/', $xarr[1]);
foreach($inner_arr as $v) {
$params[$index_part][] = $v;
}
} else {
$params[$index_part] = $value_part;
}
}
}
print_r( $params );
Output :
Array
(
[category] => Array
(
[0] => 123
[1] => 456
[2] => 789
)
[subcategories] =>
[id] => 579
[not_in_category] => Array
(
[0] => 111
[1] => 333
)
)
