PHP: Get specific content of a website - php

Question

I want to get specific content of a website into an array.
I have approx 20 sites to fetch the content and output in other ways i like.Only the port is always changing (not 27015, its than 27016 or so...)
This is just one: SOURCE-URL of Content
For now, i use this code in PHP to fetch the Gameicon "cs.png", but the icon varies in length - so it isn't the best way, or? :-/
$srvip = '148.251.78.214';
$srvlist = array('27015');
foreach ($srvlist as $srvport) {
$source = file_get_contents('http://www.gametracker.com/server_info/'.$srvip.':'.$srvport.'/');
$content = array(
"icon" => substr($source, strpos($source, 'game_icons64')+13, 6),
);
echo $content[icon];
}
Thanks for helping, some days are passed from my last PHP work :P

Answer 1

You just need to look for the first " that comes after the game_icons64 and read up to there.
$srvip = '148.251.78.214';
$srvlist = array('27015');
foreach ($srvlist as $srvport) {
$source = file_get_contents('http://www.gametracker.com/server_info/'.$srvip.':'.$srvport.'/');
// find the position right after game_icons64/
$first_occurance = strpos($source, 'game_icons64')+13;
// find the first occurance of " after game_icons64, where the src ends for the img
$second_occurance = strpos($source, '"', $first_occurance);
$content = array(
// take a substring starting at the end of game_icons64/ and ending just before the src attribute ends
"icon" => substr($source, $first_occurance, $second_occurance-$first_occurance),
);
echo $content['icon'];
}
Also, you had an error because you used [icon] and not ['icon']
Edit to match the second request involving multiple strings
$srvip = '148.251.78.214';
$srvlist = array('27015');
$content_strings = array( );
// the first 2 items are the string you are looking for in your first occurrence and how many chars to skip from that position
// the third is what should be the first char after the string you are looking for, so the first char that will not be copied
// the last item is how you want your array / program to register the string you are reading
$content_strings[] = array('game_icons64', 13, '"', 'icon');
// to add more items to your search, just copy paste the line above and change whatever you need from it
foreach ($srvlist as $srvport) {
$source = file_get_contents('http://www.gametracker.com/server_info/'.$srvip.':'.$srvport.'/');
$content = array();
foreach($content_strings as $k=>$v)
{
$first_occurance = strpos($source, $v[0])+$v[1];
$second_occurance = strpos($source, $v[2], $first_occurance);
$content[$v[3]] = substr($source, $first_occurance, $second_occurance-$first_occurance);
}
print_r($content);
}
