<?php
function makeCurlCall($url){
$curl = curl_init();
$timeout = 5;
curl_setopt($curl,CURLOPT_URL,$url);
curl_setopt($curl,CURLOPT_RETURNTRANSFER,1);
curl_setopt($curl,CURLOPT_CONNECTTIMEOUT,$timeout);
curl_setopt($curl,CURLOPT_USERAGENT,‘Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13’);
$output = curl_exec($curl);
curl_close($curl);
return $output;
}
function getImages($html) {
$matches = array();
$url_regex = ‘~http://somedomain.com/images/(.*?)\.jpg~i’;
preg_match_all($url_regex, $html, $matches);
foreach ($matches[1] as $img) {
saveImages($img);
}
}
function saveImages($name) {
$url = ‘http://somedomain.com/images/’.$name.‘.jpg’;
$data = makeCurlCall($url);
file_put_contents(‘photos/’.$name.‘.jpg’, $data);
}
$i = 1;
$l = 10;
while ($i < $l) {
$html = makeCurlCall(‘http://somedomain.com/id/’.$i.‘/’);
getImages($html);
$i += 1;
}
?>
