need help writing a list to a new file

[dcardena]

Hi,

I'm trying to generate a page via fopen() & fwrite(). I'm getting the page opened and am able to write two of three variables, but am not getting the third-

In the code below, everything's working, but I'm not getting the result I need- (I'm sure I'm just not asking for the right thing) I'm trying to write a list of files in a directory to a new file. I was hoping to store the result of the function "list_files()" as a variable, but that doesn't seem to be working.

Can you please show me where I'm going wrong?

here's the code:

<?php

// cycle through files in a directory and write image file names as js array
function list_files($folder){
	$i = '1';
	if ($handle = opendir($folder)) {
	    while (false !== ($f = readdir($handle))) { 
	        if ($f != '.' && $f != '..') {
				$grep = ereg('DS_Store$|php$|html$|htm$',$f);
				if (!$grep) {
					echo "theImages[$i] = '$f';\n";
					$i++;
				}
	        } 
	    } 
	   closedir ($handle);
	}
}

// write an include to file that pulls in first x lines
$index_top = "<?php include '../clickthrough-start.inc'?>\n"; 
// write the js array built with list_files() ||| THIS ISN'T WORKING |||
$index_middle = list_files($dest_folder_name);
// write an include to file that pulls in last x lines
$index_bottom = '<?php include "../clickthrough-stop.inc"?>';
// concatenate all three vars
$index_content = $index_top.$index_middle.$index_bottom; 
// open the file
$index_file = fopen($destination_parent_dir.$dest_folder_name.'/index.php','w'); 
// write the content
fwrite($index_file, $index_content);

?>

You should read up on functions. Storing it as a variable as-is won't do anything, because you're not returning anything from the function. You're just echoing the results within the function. You should store them as an array, then return the array, and you'll be able to do this.

thanks for your reply- Any chance you could show me a simple example?

[LordShryku]

function numbers() {
   $num = array(0,1,2,3);
   return $num;
}


$numbers = numbers();
print_r($numbers);
