i would like to execute a script every 2 minutes until i close the window.My script am executing every 2 minutes writes to a file. My script is not writing to the file. please see my interval script.
<?php
$interval = 1; //minutes
set_time_limit (0);
while (true)
{
$now=time ();
echo $now . "<BR>";
sleep ($interval * 1 - (time () - $now));
}
?>
Try
<?php
function do_stuff(){
// do something
sleep(20); // wait 20 seconds
do_stuff(); // call this function again
}
?>
You probably need to add flush() after each echo. Also sleep want time in seconds, not in minutes, so your $interval should probably be set to 60 rather than to 1.
sleep() is definitely not the solution (I wonder why is is even considered here ...) After a lot of experimenting I have arrived to the following solution: Execute "timed" PHPs (i.e. executed at intervals) via an HTML file containing a javascript timer and a frame:
<html>
<head>
<script type='text/javascript'>
var obj;
var interval = {interval_msecs};
var PHP_to_execute = "http://localhost/Work/{yourPHP}.php";
var timer = setInterval(function(){exec()}, interval);
function exec() {
obj = document.getElementById("PHParea");
obj.src = PHP_to_execute;
}
</script>
</head>
<body>
<iframe id="PHParea" src=""></iframe>
</body>
</html>
This is the basis (using a localhost). You can add whaterever feature you want to it.
<?php
set_time_limit(0);
$interval=1; //minutes
echo str_repeat(" ", 1024);
while(true) {
$now=time();
echo $now."<BR>";
sleep($interval * 60);
flush();
}
?>
sleep(120)...?
