Asynchronous shell exec in PHP

Question

I\'ve got a PHP script that needs to invoke a shell script but doesn\'t care at all about the output. The shell script makes a number of SOAP calls and is slow to complete,

Answer 1

I used this...

/** 
 * Asynchronously execute/include a PHP file. Does not record the output of the file anywhere.  
 * Relies on the PHP_PATH config constant.
 *
 * @param string $filename  file to execute
 * @param string $options   (optional) arguments to pass to file via the command line
 */ 
function asyncInclude($filename, $options = '') {
    exec(PHP_PATH . " -f {$filename} {$options} >> /dev/null &");
}

(where PHP_PATH is a const defined like define('PHP_PATH', '/opt/bin/php5') or similar)

It passes in arguments via the command line. To read them in PHP, see argv.
