[PHP] Finding last entry in a foreach() process

Question

Simple one guys.

I have an XML parsed using simplexml_load_file().

The following code:

<?php
    foreach($xml->actors->actor as $actors) {
        echo $actors.", ";
    }
?>

Gives the following result:

John Smith, Amy Adams, Charlie Doe,

How do I modify the code such that it gives:

John Smith, Amy Adams, Charlie Doe

This needs to apply across any number of entries in the array. Thanks!

Answer 1

I usually solve this problem with a simple array:

<?php
$names = array();
foreach($xml->actors->actor as $actors) {
    $names[] = $actors;
}
echo implode(", ", $names);
?>

As a matter of fact why not just say

<?php
    echo implode(", ", $xml->actors->actor);
?>

Answer 2

print implode(',',$xml->actors->actor);

Answer 3

You can get the current index in a foreach:

<?php
    foreach($xml->actors->actor as $key => $actors) {
     if ($key == (count($actors)-1) echo "Last entry!";
    }
?>

In cases like this, however, I prefer to create a temporary array with the entries first, and then implode it:

echo implode(",", $names);

Answer 4

Use the implode function.

echo implode(", ", $xml->actors->actor);

Answer 5

Did you try This solution ?

Answer 6

You can either implode the array as many people above have suggested, or assign the actor's names to a variable and concatenate that variable with each iteration, and then perform a rtrim operation on the resulting array to remove the last comma.

But for simplicity's sake, go with an implode.
