Here’s a piece of code that extracts images from an URL. This only works if the images are displayed using the IMG tag (not CSS).

This script only shows images. It doesn’t download any. The src attribute must have a full url in order for the images to show.

<?php
/*
Credits: Bit Repository
URL: http://www.bitrepository.com/
*/

$url = 'http://www.microsoft.com/';

// Fetch page
$string = FetchPage($url);

// Regex that extracts the images (full tag)
$image_regex_src_url = '/<img[^>]*'.

'src=[\"|\'](.*)[\"|\']/Ui';

preg_match_all($image_regex, $string, $out, PREG_PATTERN_ORDER);

$img_tag_array = $out[0];

echo "<pre>"; print_r($img_tag_array); echo "</pre>";

// Regex for SRC Value
$image_regex_src_url = '/<img[^>]*'.

'src=[\"|\'](.*)[\"|\']/Ui';

preg_match_all($image_regex_src_url, $string, $out, PREG_PATTERN_ORDER);

$images_url_array = $out[1];

echo "<pre>"; print_r($images_url_array); echo "</pre>";

// Fetch Page Function

function FetchPage($path)
{
$file = fopen($path, "r"); 

if (!$file)
{
exit("The was a connection error!");
} 

$data = '';

while (!feof($file))
{
// Extract the data from the file / url

$data .= fgets($file, 1024);
}
return $data;
}
?>

NOTE: You can use this script to extract images from local files too (not necessarily URLs).
