WampServer

I am using wamp on a windows machine and just wanted to invoke an exe on this via a php web page. When I am launching the php from commandline on server its working fine but when invoke same php via browser from other machine it does not work and waits forever. My php file is like this

<?php
exec("calc.exe";
?>
When I access this from client (http://localhost/exec.php) it waits forever. I know its a permission issue with apache on windows, but not sure how to fix this.

your code will execute 'calc.exe' on the server and not on the client machine where you are running the web page. So I imagine calc.exe is sitting there waiting for someone to play with it.

hey i didn't get the right answer can you please enlighten me how to solve the problem

Call exec() with all the parameters and check for errors.

And by the way this is not a PHP coder assistance site its just for those that cannot get wampserver itself running.

Hi,

It seems that you want to use "exec()" as an application launcher. Sorry, but that's not how it works.
All PHP functions able to run an executable file:
- exec()
- passthru()
- shell_exec()
- system()
do not have this executable in a window as would be done with Windows and double-click.
You MUST use the implementing return parameters and test their content.
Example:

$command = 'start /b /wait httpd.exe -v | find "built"';
$output = exec($command, $result);
if(strpos($output, "32-bit" ) !== false)
	$Apache = "32 bit version";
elseif(strpos($output, "64-bit" ) !== false)
	$Apache = "64 bit version";

or

$command = 'start /b /wait httpd.exe  -t -D DUMP_VHOSTS';
ob_start();
passthru($command);
$output = ob_get_contents();
ob_end_clean();
if(!empty($output)) {
 ... Processing command output
}

And if I put a link to the OFFICIAL documentation of the exec() function, it is for you to read it. This, a priori, you did not do, or you would understand why you want to do WILL NOT WORK.
And by the way this forum is not a PHP coder assistance site.

Use VirtulaHost: WAMPServer 2.5 Homepage the Your Projects Menu and Virtual Hosts

See errors or warnings in log files (wamp\logs\php_error.log). It is the first thing to do when code does not work.

[13-Apr-2015 11:28:02 UTC] PHP Warning: PHP Startup: Unable to load dynamic library 'c:/wamp/bin/php/php5.5.12/ext/php_intl.dll' - The specified module could not be found.

its the error am getting in the log files

This can be cleared by doing this using the wampmanager menus

wampmanager -> Apache -> Version -> 2.4.9 (Click on the version number, yours maybe different)
