Question

I’m trying to launch a CLI command from a PHP script:

in particular I wanna use this command convert a.png a.tif to convert an image to tiff.

When I launch this command from CLI it works as expected but if I launch from a PHP script with the following code it doesn’t create any tiff image in my folder:

$exec = "convert a.png a.tif";
exec($exec,$yaks,$err);
echo "<pre>";
print_r($yaks);
echo "$err";
echo "</pre>";

Moreover $yaks is empty and $err is set to 127.

I’m not an expert, why this doesn’t work as expected?

Best regards

UPDATE

I used this command instead $exec = "convert 4.png 4.tif 2>&1"; and I got in return [0] => sh: convert: command not found

This seems to me strange since I can use it from CLI!

FINAL UPDATE

Thanks a lot guys!

$exec = "/usr/local/bin/convert a.png a.tif";

This command solved the problem!
You’re great.

Answer 1

you should enter fullpath to “convert” and may be files.

err 127 – file not found
