php我的无限循环在630到660秒之间停止

Question

i wrote a site crawler and i use while loop to crawl whole web site but my loop stop after about 660 seconds .

i set set_time_limit ( 0 ) and use flush to echo output and i use sleep function,i thought my code is wrong but i test a simple while loop in my code :

        while ( 1 ) {
        sleep ( 30 );
        echo "Crawling on the go ..." . time ();
        echo "<br />";
        echo str_pad ( " ", 4096 );
        flush ();

    }

But this simple while stop too after about 660 seconds!i don't know what's my problem ! I checked WHM Process Manager on my server and i saw that my process killed ! i wanna know server firewall kill my process because of something like CPU or RAM usage ? plz help me!

You need to write set_time_limit(0); at top of the page after PHP opening tag. This has worked for me .. I hope this will also work for you too..
