TalkPHP - View Single Post - how to delete an element from an array without knowing its index position

Yes. That's another way to do it, which is pretty much as below. Although I added them into a function for him.

php Code:

while (($iKey = array_search($szSearch, $aArray)) !== false)
{
    unset($aArray[$iKey]);
}

Then he also wanted to delete all the items whilst supplying many values, too. Which is just a loop inside a loop:

php Code:

foreach ($mSearch as $szSearch)
{
    while (($iKey = array_search($szSearch, $aArray)) !== false)
    {
        unset($aArray[$iKey]);
    }
}

Unless array_keys allows you to pass in an array, then you're also going to need a loop inside a loop.
