Permission denied on PHP as a shell script

Question

I'm trying to follow the instructions here: http://www.php.net/manual/en/features.commandline.usage.php

• I created a file named "vardump"

• Added this code to the file:

  #!/usr/bin/php
  <?php
  var_dump($argv);
  ?>
  

• did chmod +x vardump

• but I'm getting a permission denied error when executing the file:

  shiki@Etna:~/projects/tests$ ./vardump
  bash: ./vardump: Permission denied
  shiki@Etna:~/projects/tests$ sudo ./vardump
  sudo: unable to execute ./vardump: Permission denied
  

What could be the problem? I'm running Ubuntu 10.04.

Executing it like this works though:

shiki@Etna:~/projects/tests$ php vardump
array(1) {
  [0]=>
  string(7) "vardump"
}

Here are the file permissions:

shiki@Etna:~/projects/tests$ ls -l
-rwxrwxrwx 1 root root   41 2010-06-23 07:25 vardump

shiki@Etna:~/projects/tests$ ls -l /usr/bin/php
lrwxrwxrwx 1 root root 21 2010-06-02 15:34 /usr/bin/php -> /etc/alternatives/php

Solved it. Based on all your answers, I suspected the problem is not in php at all. I'm running the script on a NTFS mount so I tried to move it to the root mount and it worked there. So I added exec to /etc/fstab and it worked.

This answer also gave me the clue for it. Thanks a lot for all your help!
