php exec无法通过脚本运行，但可通过命令行运行

Question

I try to execute command

convert -geometry x30 C:\xampp\htdocs\schuleweise\engine\Shopware\../../media/image\3573349700001A.jpg C:\xampp\htdocs\schuleweise\engine\Shopware\../../media/image\thumbnail\3573349700001A_30x30.jpg

Which works from command line, but not from the script with exec($command). can anybody help me here ?

Answer 1

exec() commands require full path to command in order to work in php.

Try it like this,

exec('usr/bin/convert -geometry x30 ..', $output);

Answer 2

Try to alternate function to exec()

system($shell_command, $response_var);

So in your case:

system("convert -geometry x30 C:\xampp\htdocs\schuleweise\engine\Shopware\../../media/image\3573349700001A.jpg C:\xampp\htdocs\schuleweise\engine\Shopware\../../media/image\thumbnail\3573349700001A_30x30.jpg", $output);
