PHP cron作業重疊

您好我寫了幾個月前的腳本在Perl檢查的工作重疊PHP cron作業重疊

use Fcntl ':flock'; 
INIT { 
    my $waitcount=12; # possible attemtps to run script 
    my $waitseconds=300; # wait for $waitseconds each attempt 
    my $lockstatus=0;#no lock was attained 
    while ($waitcount > 0){ 
      if (open LH, $0){ 
       while ($waitcount > 0){ 
        if (flock LH, LOCK_EX|LOCK_NB){ 
         $waitcount=0;#signal end of waiting 
         $lockstatus=1;#lock was attained 
        } 
        else{ 
         --$waitcount;#decrement waitcount 
         print "waiting to be able to lock $0\n"; 
         sleep $waitseconds; 
        }#end else 
       }#end while 
      }#end if 
      else{ 
       --$waitcount;#decrement waitcount 
       print "waiting to be able to open $0\n"; 
       sleep $waitseconds; 
      }#end else 
    }#end while 
    if ($lockstatus == 0){ 
     die "no lock was attained\n"; 
    }#end if 
}

我想知道，如果我們能做到在PHP中類似的事情..

如何整合與您正在運行的PHP作業的一部分目前的PHP代碼？
