Example
A runnable snippet:
// Ignore user aborts and allow the script // to run forever ignore_user_abort(true); set_time_limit(0); echo 'Testing connection handling in PHP'; // Run a pointless loop that sometime // hopefully will make us click away from // page or click the "Stop" button. while(1) { // Did the connection fail? if(connection_status() != CONNECTION_NORMAL) { break; } // Sleep for 10 seconds sleep(10); } // If this is reached, then the 'break' // was triggered from inside the while loop // So here we can log, or perform any other tasks // we need without actually being dependent on the // browser.
