Is it correct to put 'function' in front of chdir() -- an existing php function?

Actually, the solution is part of the error mesage:

Code:

PHP Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING, expecting '&' or T_VARIABLE in /home/username/php/project1.php on line 3

The clue is in the last part:

Quote:

expecting '&' or T_VARIABLE in /home/username/php/project1.php on line 3

Now, look at your code, what's on line 3?

Code:

function chdir("..");

The PHP parser says it's invalid syntax. The question you now need to ask yourself is: "why is that invalid?" and go from there

Hi i have been going through the project 1 php academy book and have come across and experiencing problems! May be i am making a simple fault.

I have got to page 22 and all work well! Got the right output at the terminal. When i got to page 23 and added the extra code i start to get error's when running the script.

This was the page 23 code i added to the script.

chdir("..");
subdir_scan(".")

This is the complete code and error's.

Code:

<?php

function chdir("..");
subdir_scan(".");

subdir_scan($dir){
$files = scandir($dir);
foreach($files as $files){
   if ($files==".")continue;
   if ($files=="..")continue;

   print "$dir/$files\n";

   if (is_dir("$dir/$files")){
      subdir_scan("$dir/$files");
      }
   }
}

subdir_scan(".")
?>

Error message.

Code:

PHP Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING, expecting '&' or T_VARIABLE in /home/username/php/project1.php on line 3

Any help in what i have done wrong would be great! I'm sure it's a simple mistake i've made but i have checked over and over again!

I am a simple newbie forgive me for not spotting the problem.
