I want extract the path of images from a html page using PHP-preg_match_all(), the pattern is as follows

 <img width="148" height="110" src="https://link1">
 <img width="104" height="129" src="https://link2">
 <img width="150" height="129" src="https://linkn">

I want to all the image path in an array.

Try:

preg_match_all("/<img .*?(?=src)src=\"([^\"]+)\"/si", $html, $m); 
print_r($m);

OR

preg_match_all("/<img .* src=\"([^']*?)\">/", $html, $m);
echo "<pre>";
print_r($m[1]);

It outputs some html content before the array - Alfred Francis 2012-04-04 04:51
you could use the second on - Sudhir Bastakoti 2012-04-04 07:35

You can use simple regex to do that,

Use:

preg_match_all('/<img .*?(?=src)src=\"([^\"]+)\"/si', $imglink, $result, PREG_PATTERN_ORDER);

$imglink is each of your image link

and

$result is the result in array.

with looping:

<?php 
$subject  = array (
     '<img width="148" height="110" src="https://link1">'
    , '<img width="104" height="129" src="https://link2">'
    , '<img width="150" height="129" src="https://linkn">'
);

foreach ($subject as $imglink) {
preg_match_all('/<img .*?(?=src)src=\"([^\"]+)\"/si', $imglink, $result, PREG_PATTERN_ORDER);
$link[] = $result[1];
}

echo "<pre>";
print_r ($link);

 ?>
