I have an index array

CODE

$array[0] = 10;
$array[1] = 12;
...

Its kinda late and I'm falling asleep now but I had a quick look through PHP.net, and could not find what I'm after, Maybe I'm too sleepy, sorry, but if anyone knows off the top of their head a way to removed members in that array based on its value, i.e. I wanna remove values 12. I don't really want to do a loop but if I cant find any existing function to do it, then I may have to.

Thanks for any help.

You may have to make your own function or set up for this. But i did a quicky function that should work fine for your needs:

CODE

function remove_element($arr, $val){
foreach ($arr as $key => $value){
if ($arr[$key] == $val){
unset($arr[$key]);
}
}
return $arr = array_values($arr);
}

You can rename the function if you want.

Thanks again for the help Truefusion. Its too bad PHP does not have a array function for this specific task itself, they seem to have many other functions for other kinds of array modifications.

Remove A Value From A Php Array Based On Its Value

This is really good... I needed a script to find the only file in a folder, but it returned '.' and '..' and then the file... Now I just do this:
<?php
$return = delete_value($return, '.');
$return = delete_value($return, '..');
?>
Thanks...

Remove A Value From A Php Array Based On Its Value

Replying to truefusion
Is there away to chop an array depending on the value of a sub-array?

I.E:
$array[0] = 10;
$array[1] = 12;
$allcontent = array("page1", "page2", array("page3a", "page3b"), "page4", "page5");

If my function finds "page3b" I want it to end the parent array at "page2"/
I.E.:
$allcontent = array("page1", "page2");

If this can't be done how about just removing the sub array?
I.E.: $allcontent = array("page1", "page2", "page4", "page5");
