Echo'ing end of array

Hi Guys.

I'm having problems with the below code. When I try and echo the end of the array 'echo end($i);' I don't have anything echo'ed.

I've tried test using:
$i = array(2,6,4,3,56,3);
echo end($i);

This works I get '3' echo'ed.

Can anyone see what I'm doing wrong?


Many thanks

<?php

$next_p = $_GET['next_p'];
	
$filePath = $PATH .'../images/gallery';

$dir = opendir($filePath);

while ($file = readdir($dir)) { 

if (eregi("\.jpg", $file)) { 
  
$string  .= $file . ',';
}}

$i = explode(',', $string);
   
echo end($i);

?>

Trying print_r($i); First to make sure you aren't doing anything wrong with the array.

 

Try echoing $string just to make sure it has the correct string you want, it looks like it should work.

 

<?php

$next_p = $_GET['next_p'];
	
$filePath = $PATH .'../images/gallery';

$dir = opendir($filePath);

while ($file = readdir($dir)) { 

if (eregi("\.jpg", $file)) { 
  
$string  .= $file . ',';
}}
$string = substr_replace($string ,"",-1);
$i = explode(',', $string);

echo end($i);

?>

PHP:

simple the last character of your string is "," so when u explode it last array will be empty so we remove last ",".

 

Alternatively you could just do this...

<?php

$next_p = $_GET['next_p'];
   
$filePath = $PATH .'../images/gallery';

$dir = opendir($filePath);

while ($file = readdir($dir)) {

if (eregi("\.jpg", $file)) {
 
$files[] = $file;
}}

$string = implode(',',$files);
echo array_pop($files);

?>

remember there is always more than one way to do things.
