[SOLVED] exec() issue on my Mac

[ultrus]

Hi,

The following works fine:

<?php
$command = 'ls';
exec($command, $output);
print_r($output); //all files and folders are listed in my current php file directory
?>

 

However, when I try to run a 3rd party program of any kind from command line, nothing happens. No errors. No results either. I can echo out the command I'm running, copy, paste into terminal, and it runs fine.

 

I'm thinking it's some kind of user permission issue? Any guess on how to resolve this?

 

I'm using MAMP.

 

Thanks much.

What is the command you are running? Make sure you are using the FULL path to the file. Also, try running it like this:

/full/path/to/file 2>&1

that will send any output that is going to STDERR to STDOUT

Hello rhodesa,

Thanks for the quick feedback. Your tip returned an error message array.

 

command:

swift "test" 2>&1

 

output:

Array

(

    [0] => dyld: Symbol not found: __cg_jpeg_resync_to_restart

    [1] =>  Referenced from: /System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/ImageIO.framework/Versions/A/ImageIO

    [2] =>  Expected in: /Applications/MAMP/Library/lib/libJPEG.dylib

    [3] =>

)

 

What's supposed to happen is the computer will say "hello" using Cepstral's text-to-speech engine and command line program they call Swift.

 

Not sure what this has to do with jpegs. Any thoughts?: I'll start digging around.

Can you post the actual PHP code you are executing?

[ultrus]

Sure thing. Here it is in full:

 

<?php
class Swift {
public $defaultVoice; //not used yet

public function __construct() {
	//stuff soon
}

public function sayHello() {
	$output = "";

	$command = 'swift "test" 2>&1';

	exec($command, $output);
	print_r($output);

	return true;
}
}

//example usage:
$swift = new Swift();
$swift->sayHello();
?>

[ultrus]

Ah got it!

 

It's a MAMP bug. The solution is this:

 

export DYLD_LIBRARY_PATH=""; swift "test"

 

Thanks again for your help.
