timeout part of a script

Silly question

Im using

implode('', file($url);

in a loop to open pages and check for backlinks.

Is there a way to make it only check for 5 seconds and then go to the next $url?

 

You can use this with safe_mode ON only.

if(!ini_get('safe_mode')) {
    set_time_limit(240);
    ini_set('max_input_time', 300);
}

PHP:

If Safe Mode is on, then never mind that - I would be helpless.

You can check if safe_mode is on, in your php.ini or by using

php_info();

PHP:

 

I dont think that will work.

I want to do something like this:

while (looping though $urls){

while( <less than 5 seconds or $content is found> ){
$content = implode('', file($url));
}

}

is there a way to do that?

 

Well, there's no need to set a time limit, rather than how far microtime() can be delimited. Use something along these lines.

$time = microtime();
$startTime = // MICROTIME+HOWLONGFROMTHEN 
for ($i = $time; $i >= $startTime; $i--):

      if ($CONTENT) {
        echo "Something here.";
      } else {
        $startTime--;
        if ($startTime<=0):
          // Loop went out the back door
          break;   // escape from the for loop
        }
      }
}

PHP:

 

Look into moving to cURL for retrieving the pages. cURL has among other goodies, connection and read timeout arguments available.

 

Why aren't you using

file_get_contents($url)

PHP:

?

 

I believe he wants to return an array (file) instead of a string (file_get_contents) which is why he used implode later on in the code.

 

But he had implode('', file(__)) on a single line!
