Quick summary and next steps (clarifies and answers )

The little check posted by only detects whether PHP’s exec-style functions are permitted — it does not “turn them on.” Those functions are controlled by the php.ini setting disable_functions and other server-level settings; to allow them you must edit the active php.ini (or ask your host) and restart the web server. Use phpinfo() in a test page to see the “Loaded Configuration File” so you edit the correct php.ini. (php.net)

Windows-specific gotchas to verify before trying to run an .exe from PHP

The webserver process runs under a specific Windows account (IIS application-pool identity, Apache service account, etc.). That account must have filesystem access to the exe and to any data files you pass. Also, processes started by a service won’t show a GUI (Session 0 isolation) — server-side runs must be headless/console-mode or run via a scheduled task/service. Grant the app-pool identity the proper NTFS rights or use a dedicated identity with the needed permissions. (learn.microsoft.com)

Practical, safer approach and troubleshooting checklist

Prefer proc_open() (or the array-form command that bypasses cmd.exe) so you can capture stdout/stderr and control quoting; on older PHP builds wrap each argument with the proper escaping function before passing to a shell. Always quote/escape user data to avoid injection. Example pattern (replace variables with your paths and test from CLI first):

// build command as an array (PHP 7.4+ lets proc_open accept array to avoid cmd.exe)
$cmd = [$exePath, '-f', $dataFile];
$options = ['bypass_shell' => true];
$descriptors = [['pipe','r'], ['pipe','w'], ['pipe','w']];
$proc = proc_open($cmd, $descriptors, $pipes, null, null, $options);
// read $pipes[1] (stdout) and $pipes[2] (stderr), then proc_close()

If you must pass a single string command through the shell, escape each argument with the appropriate helper (use the platform-aware escaping function). Test the command on the server CLI as the same user the webserver uses, check return/code/output, and if the app is long-running consider queuing it (Task Scheduler/service) rather than blocking the PHP request. (php.net)

Troubleshooting tips: confirm php.ini location with phpinfo(), check disable_functions, run the exe from an elevated command prompt as the webserver identity (or give that identity rights), and check Windows Event Log for failures.

You will need to compile or allow the option to execute on the server with in php.

Check to see if php allow the exec command.

<?php
function exec_enabled() {
  $disabled = explode(', ', ini_get('disable_functions'));
  return !in_array('exec', $disabled);
}
?>

You will need to add executable permissions to the file.

You can then:

<?php
exec("C:\\PATH\\TO\\FILE.exe")
?>

Hope that helps, its not really a very safe thing to have enabled, do not allow users to pass directly to this command.

For more info check the php man pages.
