web - Difference between in PHP shell-scripts and PHP on MAMP? -

this weird me. wonder why. wrote php script validate syntax of php script named test.php

 <?php     print("hello world");     ?>

the validating script index.php is:

#!/usr/bin/env php <?php exec("php -l test.php", $error, $retcode); echo($retcode . "<br />"); var_dump($error); ?>

when run on command line php index.php, generates output:

0<br />array(1) {   [0]=>   string(37) "no syntax errors detected in test.php" }

this looks me. however, when run on localhost generates output:

#!/usr/bin/env php 5 array(0) { }

why $retcode set 5? also, i'm on php5.3

okay, figured out.

the problem have use php interpreter on mamp, is:

exec("/applications/mamp/bin/php/php5.3.6/bin/php -l $file",$error,$retcode);

the 1 used before php interpreter on os x.
