Happy 4th! I've done a lot of looking around searched the forums, and google... can't find a solution.

 

Error:

Fatal error: Call to undefined function getDirectory() in C:\xampp\htdocs\project\session_var.php on line 22

 

<?php

							$dh = @opendir( $path ); 
							$i = -2;

							while( false !== ( $file = readdir( $dh ) ) && ( $i < 5) ) 
								{ 
									$i++;
									if( !in_array( $file, $ignore ) )
										{ 
											if(is_dir( "$path/$file" ) )

Because your function definition is inside of a conditional statement, the definition must come before the call to the function.

Thanks that worked, but I didn't read any resources that made that distinction.

Functions need not be defined before they are referenced, except when a function is conditionally defined as shown in the two examples below.

 

When a function is defined in a conditional manner such as the two examples shown. Its definition must be processed prior to being called.
