ereg and img tag

Hi experts

I need to retreive the value of the "src" from the tag "img" into an html string.

for exemple:
html -> this is a test <img src='test.jpg'> test
also html -> this is a test <img src="test.jpg"> test
It should return "test.jpg"

<?php

$text = "this is a test <img src='test.jpg'> test";
$pattern = "(.*)<img src='(.+)'>(.*)";
$matches = array();

ereg( $pattern, $text, $matches );

print_r($matches);
echo "<br/>";
echo "The text you what is in the 2nd group and is '". $matches[2] . "'";
?>

Note: The pattern used above (.*)<img src='(.+)'>(.*) expects <image and src=' to be separated by one space and for thesrc to be delimited by apostrophes rather than double quotes.

First, you shouldn't be using the ereg function, it's on its way out. Use PCRE functions instead... preg_match()

Here's a regular expression that actually works, and actually capture all the images if needed...
<?php
 
$html = array(
    'blah test <img alt="blue"
src ="image.jpg" width="12" /> test message',
    '<img src=\'test.jpg\'>',
    '<p>some text<img lowsrc="blackwhite.gif" src="fullcolor.jpg" title="Low/Res"/> <img src="icon.png" height="12"></p>',
);
 
 
 
$re = '/<img\s*[^>]*\s+src\s*=\s*([\'"])([^"\']+)\1\s*[^>]*>/im';
 
foreach ($html as $h) {
    // Capture all the <img> information
    preg_match_all($re, $h, $matches);
 
    echo "\r\n".$h.' ===> ';
    print_r($matches[2]);
    echo "\r\n";
 
    // Captures only the first match
    preg_match($re, $h, $matches);
 
    echo "\r\n".$h.' ===> '.$matches[2]."\r\n";
 
}
 
?>
