Array Remove

Is there an acutal function in PHP for removing an element of an array?

eg: array1 = ("zero", "one", "two", "three");
array1 = remove_element( array1, 2 );
// array1 now contains ("zero", "one", "three");

I have been trying the unset method but this seems to be corrupting my
array (which is holding a set of objects);

I can knock something together with aray_merge, array_splice and
similar but just didn't want to reinvent the wheel.

Thanks,

Unset() is the method given in the manual.

In what way is it corrupting your array?

What's wrong with using array_splice($array, $index, 1)?

I was getting a message basically telling me that PHP could not use my
objects corectly. I got it working by using array_merge after unset.

No idea why it suddenly works after array_merge though but it will do.

My question was really just if anyone knew of a method/funciton to
remove them without having to mess around with splitting and merging
arrays.

re: Array Remove

There is no native PHP process to do the equivalent of "array_remove()"
as of yet. Your best would be to slap together a function using
unset($array['element']), as I've had to do.

Bear in mind that in future additions to PHP an "array_remove()"
function might someday exists, it's best that when you create it to
wrap the function around a "function_exists()" conditional block:

if (!function_exists('array_remove')) {
function array_remove($element, &$array, $willSearchKeys) {
// EXERCISE LEFT TO THE STUDENT!
}
}
