Hey guys I'm having some issues with the speed of my script. I'm a novice I know so getting past that - what suggestions would you have to speed up my script?
I was originally just reading
in the index.
php and then searching the <head> of the page for an
array of strings. Then I read about the get_meta_tags and went that way. Then I had issues with some sites having 300 redirects
in place so I used curl to check the URL existed and to speed up things but it's still taking 5 minutes or so to execute.
<?php
function url_exist($url){
$c=curl_init();
curl_setopt($c,CURLOPT_URL,$url);
curl_setopt($c,CURLOPT_HEADER,1);
curl_setopt($c,CURLOPT_NOBODY,1);
curl_setopt($c,CURLOPT_RETURNTRANSFER,1);
curl_setopt($c,CURLOPT_FRESH_CONNECT,1);
if(!curl_exec($c)){
return false;
}else{
return true;
}
curl_close($c);
}
function checkVersion($url){
$tags = get_meta_tags($url);
if (is_array($tags) && array_key_exists('generator', $tags))
{
$v = "<span style='background-color:#7BF55D;color:#A3A0A0'>".$tags['generator']."</span";
}else{
$v="<span style='background-color:#F55D67;color:#A3A0A0'>Metatag not found!</span>";
}
return $v;
}
$row = 1;
echo "<table>";
if (($handle = fopen("url.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
$num = count($data);
$row++;
for ($c=0; $c < $num; $c++) {
if(url_exist($data[$c])){
echo "<tr><td>".$data[$c]."</td><td>".checkVersion($data[$c])."</td></tr>";
sleep(2);
}else{
echo "<tr><td>".$data[$c]."</td><td><td><span style='background-color:#F55D5D;color:#A3A0A0'>URL not valid!<span></td></tr>";
}
}
}
fclose($handle);
}
echo "</table>";
?>
