PHP Regex Matching Image URLs

Question

This is my Image Url PHP Code.

$GetImage = 'https://lh6.ggpht.com/hWXw7YRl9DpSMewd29xT9rvxcgnmGXeXSY9FTaPc3cbBCa-JO8yfwSynmD5C1DLglw=w124';

preg_match_all("/https://\w\w\d.\w+.com/[\w-]+=\w\d{2,3}/", $GetImage, $Result, PREG_SET_ORDER);

its working for me, but i want to extract "[\w-]" pattern results, in other words, i want to extract "hWXw7YRl9DpSMewd29xT9rvxcgnmGXeXSY9FTaPc3cbBCa-JO8yfwSynmD5C1DLglw" this string from my image Url...

Please anybody help my to solve this problem....

thanks

Em, you did read the documentation of preg_match? You did try putting braces (()) around that [\w-]+ sequence? — arkascha

I feel it's overkill to try to match the entire URL using a regular expression. I suggest you parse the URL first using PHP's built-in function parse_url().

<?php

$str = 'https://lh6.ggpht.com/hWXw7YRl9DpSMewd29xT9rvxcgnmGXeXSY9FTaPc3cbBCa-JO8yfwSynmD5C1DLglw=w124';

// Parse the URL before applying a regex. Only get the path part. Use substring to remove the leading slash
$path = substr( parse_url( $str, PHP_URL_PATH ), 1 );

$pattern = '/([^=]+)/';
$matches = array();

if ( preg_match( $pattern, $path, $matches ) ) {
    // Regex matched

    $id = $matches[1];

    // Outputs: string 'hWXw7YRl9DpSMewd29xT9rvxcgnmGXeXSY9FTaPc3cbBCa-JO8yfwSynmD5C1DLglw' (length=66)
    var_dump( $id );
}

?>

Note that the snippet does not check the domain name. You can easily adjust the script to do so by not limiting the parse_url() function to only return the path, but also the other parts.

Try like this

$GetImage = 'https://lh6.ggpht.com/hWXw7YRl9DpSMewd29xT9rvxcgnmGXeXSY9FTaPc3cbBCa-JO8yfwSynmD5C1DLglw=w124';
preg_match_all('#https://.*\.com/([\w-]+=\w\d{2,3})#iU', $GetImage, $match, PREG_SET_ORDER);
print_r($match);
