_I want to group this array_ What does that mean? Group on what criteria? all elements are the same... what have you tried? — B001ᛦ, Nov 14 '17 at 13:20
Do you mean [`array_unique`](http://php.net/manual/en/function.array-unique.php)? — iainn, Nov 14 '17 at 13:22

Look at array_unique which will remove duplicates from the array.

<?php
// Assuming your array is stored as $arr
$arr = array(
    '[email protected]',
    '[email protected]',
    '[email protected]'
);
// Remove the duplicates
$arr = array_unique($arr);
// Print to test
echo '<pre>'.var_export($arr, TRUE).'</pre>';

I assume you wish to remove duplicates, luckily PHP has a function called array_unique

Use it like so:

$array = array( "[email protected]", "[email protected]", "[email protected]" );

$array = array_unique( $array );
