Convert String back into an array PHP

Question

I have two different torrent scrapping classes and I want to combine them, they are working fine separately but the only problem is, when I convert my string into an array, it does not work.

That's the codes I am using so far.

<?php
require 'scraper.php';
require 'tor-info.php';

$scraper = new Scrapeer\Scraper();
$torrent = new Torrent( './test.torrent' );

$hashix = $torrent->hash_info();
var_dump($torrent->scrape()); // shows trackers list like this array(21) { ["udp://tracker4.piratux.com:6969/announce"]=> bool(false) ["udp://tracker.trackerfix.com:80/announce"]=> bool(false) ["udp://tracker.pomf.se:80/announce"]=> bool(false) ["udp://torrent.gresille.org:80/announce"]=> bool(false) so on..

$trackers = array( "udp://tracker4.piratux.com:6969/announce", "udp://tracker.trackerfix.com:80/announce", "udp://tracker.pomf.se:80/announce" ); // now here we need that trackers list
$hash = array( $hashix );
$info = $scraper->scrape( $hash, $trackers );

//print_r( $info );

echo '<br><hr>';

foreach ($info as $key => $value) {
echo 'SEEDS :' .$value['seeders'].'<br />';
echo 'LEECHES :' .$value['leechers'].'<br />';
}

?>

In the first part I converted the array into String to get the readable result, and then in the second part I needed to convert that string back into single array to produce the result.

I need to get recombining like this $trackers = array ("udp://tracker4.piratux.com:6969/announce","udp://tracker.trackerfix.com:80/announce") — Aliza

It displays the result like this array ( 0 => '"udp://tracker4.piratux.com:6969/announce"', 1 => '"udp://tracker.trackerfix.com:80/announce"', 2 => '"udp://tracker.pomf.se:80/announce"' ) — Aliza

yes, its the expected result the only problem is the Converting string back into single array, after it is converted into string — Aliza

I need those to work like this $trackers = array($tracker); $hash = array($hashix); $info = $scraper->scrape( $hash, $trackers ); — Aliza

Why don't you just make them an array to begin with?

<?php
require 'scraper.php';
require 'tor-info.php';

$scraper = new Scrapeer\Scraper();
$torrent = new Torrent( './test.torrent' );    
$hashix = $torrent->hash_info();
$trackers = array_keys($torrent->scrape());

$hash = array( $hashix );
$info = $scraper->scrape( $hash, $trackers );

echo '<br><hr>';

foreach ($info as $key => $value) {
   echo 'SEEDS :' .$value['seeders'].'<br />';
   echo 'LEECHES :' .$value['leechers'].'<br />';
}

ok I have tried like this

$trackerArray = []; foreach($torrent->scrape() as $trackx => $k) {     $trackerArray[] = $trackx; } $tracker = '"'.implode('","',$trackerArray).'"'; $trackers = array($tracker); $info = $scraper->scrape( $hash, $trackers );

but still not working

@Aliza the point was to have the array since you needed it for $scaper->scrape($hash, $trackersArray); See the update.

Ok I have tried like this now

$trackerArray = array_keys($torrent->scrape()); 	$tracker = '"'.implode('","',$trackerArray).'"'; 	$trackers = array($tracker);	 	$hash = array('40e22987e52a8a90b2513792266905dae84cb29f'); 	$info = $scraper->scrape( $hash, $trackers );

but still doesn't work

It works like this,

$trackers = array("udp://tracker4.piratux.com:6969/announce","udp://tracker.trackerfix.com:80/announce"); 	 	$hash = array('40e22987e52a8a90b2513792266905dae84cb29f'); 	$info = $scraper->scrape( $hash, $trackers );

but when we use that string into a single array, it does not work, and i need to convert that string into an array, because that string is dynamic

Since your string looks like this (from comment) : "udp://tracker4.piratux.com:6969/announce","udp://tracker.trackerfix.com:80/announce" you could use PHP's explode() function like so:

$recombined = explode(',', str_replace('"', '', $trackers));

thanks for your kind response, but if I don't use quotes around the string, it does not work in the array.
