[SOLVED] Remove element from array

[PHPTOM]

Say I have

<?PHP
$ar = array("test", "php", "freak");
?>

How could I remove the test element from it? So then its only

<?PHP
$ar = array("php", "freak");
?>

 

Thanks :)

look at array_pop and array_shift

Or something like.

<?PHP
$ar = array("test", "php", "freak");

foreach ($ar as $k => $v)
{
if ($k == "test")
unset($ar[$k]) ;
}
?>

Or just unset()

don't use the foreach method that is looping through a whole array which could be 10 thousand items long just to extract 1 item.

 

Unset works too but then the keys don't reset

There are many ways this can be done. No specific way is correct. Many variations just depends on what you want to use it for.

If you want to search for an element, and then remove it, you can use array_search().

 

<?php
$ar = array("test", "php", "freak");
$rem = 'test';
unset($ar[array_search($rem)]);
//$ar == array("php", "freak");
?>

 

And it will only work for the first occurrence of the searched string. If you want to remove all occurrences of an element, read up on using array_keys() with the optional search_value parameter.

THanks for all the responses. Basically I had a range from 1-80, then I had to do a while from the database to remove certain numbers. So then I could select  a random number what hasn't already been chosen. Unset works fine, because  I shuffle it afterwords. Thanks again!
