How to use wget in PHP script

[jpoltora]

Hi,

I would like to run script to send few requests per secend to the server just for testing.
I have been told that I can use wget like this

eg

<?php
while(true)
{
wget http://server.com
sleep(3);
}
?>

But is giving me error on line wget http://server.com

Could someone tell me what I'm doing wrong.

Thanks

hi,
because u wanna run an external program (wget) u gotta use the system function (www.php.net/system) to execute wget. also read the docu on usin backticks (http://de.php.net/manual/en/language.operators.execution.php), which could be an alternative way for u. Also check the 'see also' links on these pages.

So how do you use system function?

Something like this
system(wget http://server.com);

[Natty_Dreadlock]

u gotta put the command into quotes:
system("wget http://server.com");
System will pass-through any outputs of wget, so also have a look at the backtick operator which will allow u to store the output in some var:

$output = `wget [url]http://server.com[/url]`;
echo "<pre>$output</pre>";
