list of urls in associative array

My string looks like this:

http://localhost/layerthemes/wp-content/uploads/2014/05/46430454_Subscription_XXL-4_mini.jpghttp://localhost/layerthemes/wp-content/uploads/2014/05/Eddy-Need-Remix-mp3-image.jpghttp://localhost/layerthemes/wp-content/uploads/2013/03/static-pages.png

How do I extract each urls in array like this:

array( 
  0 => 'http://localhost/layerthemes/wp-content/uploads/2014/05/46430454_Subscription_XXL-4_mini.jpg' 

  1 => 'http://localhost/layerthemes/wp-content/uploads/2014/05/46430454_Subscription_XXL-4_mini.jpg' 

  2 => 'http://localhost/layerthemes/wp-content/uploads/2014/05/46430454_Subscription_XXL-4_mini.jpg' 
)

This is how i tried with no avail:

  $imgss = 'http://localhost/layerthemes/wp-content/uploads/2014/05/46430454_Subscription_XXL-4_mini.jpghttp://localhost/layerthemes/wp-content/uploads/2014/05/Eddy-Need-Remix-mp3-image.jpghttp://localhost/layerthemes/wp-content/uploads/2013/03/static-pages.png';

    preg_match_all(
        "#((?:[\w-]+://?|[\w\d]+[.])[^\s()<>]+[.](?:\([\w\d]+\)|(?:[^`!()\[\]{};:'\".,<>?«»“”‘’\s]|(?:[:]\d+)?/?)+))#",
        $imgss
    ); 

    foreach($imgss as $imgs){
        echo '<img src="'.$imgs.'" />';
    }

Any help would be appreciated. needless to say I am very weak in php

Thanks

Exploding is fine but perhaps you should also validate the inputted links, ive put together this which will let you know the inputted links need to be on a new line or have a space between them, then it will validate the links and create a new array of valid links that you can then do something with.

<?php
if($_SERVER['REQUEST_METHOD'] == 'POST' & !empty($_POST['links'])){

    //replace all \r\n and \n and space with , delimiter
    $links = str_replace(array(PHP_EOL, "\r\n", " "), ',', $_POST['links']);

    //explode using ,
    $links = explode(',', $links);

    //validate links by going through the array
    foreach($links as $link){

        //does the link contain more then one http://
        if(substr_count($link, 'http://') >1){
            $error[] = 'Add each url on a new line or separate with a space.';
        }else{

            //does the link pass validation
            if(!filter_var($link, FILTER_VALIDATE_URL)){
                $error[] = 'Invalid url skipping: '.htmlentities($link);
            }else{

                //does the link contain http or https
                $scheme = parse_url($link, PHP_URL_SCHEME);
                if($scheme == 'http' || $scheme == 'https'){
                    //yes alls good, add to valid links array
                    $valid_links[] = $link;
                }else{
                    $error[] = 'Invalid url skipping: '.htmlentities($link);
                }
            }
        }

    }

    //show whats wrong
    if(!empty($error)){
        echo '
        <pre>
        '.print_r($error, true).'
        </pre>';
    }

    //your valid links do somthing
    if(!empty($valid_links)){
        echo '
        <pre>
        '.print_r($valid_links, true).'
        </pre>';
    }

}?>
<form method="POST" action="">
    <textarea rows="2" name="links" cols="50"><?php echo (isset($_POST['links']) ? htmlentities($_POST['links']) : null);?></textarea><input type="submit" value="Submit">
</form>

Perhaps it will help.

Here's an example, if you have control over this entire process.

Your form:

<form id="myform" method="POST">

</form>

Your javascript (using jquery):

<script>

var myurls = getUrls();

$('<input>').attr({
    type: 'hidden',
    name: 'myurls',
    value: JSON.stringify(myurls),
}).appendTo('#myform');

// gathers your URLs (however you do this) and returns them as a javascript array
function getUrls() {

    // just return this as a placeholder/example
    return ["http://localhost/layerthemes/wp-content/uploads/2014/05/46430454_Subscription_XXL-4_mini.jpg", "http://localhost/layerthemes/wp-content/uploads/2014/05/Eddy-Need-Remix-mp3-image.jpg", "http://localhost/layerthemes/wp-content/uploads/2013/03/static-pages.png"];
}

</script>

Your PHP:

$myurls = json_decode($_POST['myurls']);

var_dump($myurls); // should be the array you sent

You could do this with AJAX too if you want. Or make the form automatically submit.

If there are no spaces in string you can use:

$string = 'http://localhost/layerthemes/wp-content/uploads/2014/05/46430454_Subscription_XXL-4_mini.jpghttp://localhost/layerthemes/wp-content/uploads/2014/05/Eddy-Need-Remix-mp3-image.jpghttp://localhost/layerthemes/wp-content/uploads/2013/03/static-pages.png';

$string = str_replace( 'http', ' http', $string );
$array = array_filter( explode( ' ', $string ) );


print_r( $array );

How about:

$input = "http://localhost/layerthemes/wp-content/uploads/2014/05/46430454_Subscription_XXL-4_mini.jpghttp://localhost/layerthemes/wp-content/uploads/2014/05/Eddy-Need-Remix-mp3-image.jpghttp://localhost/layerthemes/wp-content/uploads/2013/03/static-pages.png";
$exploded = explode("http://", $input);

$result;
for ($i = 1; $i < count($exploded); ++$i)
{
    $result[$i - 1] = "http://" . $exploded[$i];
}
