TalkPHP - View Single Post - some problem in array_search and the use of unset

array_splice is used to replace content and it doesn't throw an exception, so there is no need to put it on a try-catch block.

to delete an element (the value and the index too) you can use this:

PHP Code:


			
$arr = array('4', 'sdf', 'seoij', 'sodifj');



$arr = array_values(array_diff($arr, array('sdf')));

so you can make it a function:

PHP Code:


			
function array_remove($arr, $value){

    return array_values(array_diff($arr, array($value)));

}



//then you can use this function like this

$arr = array('4', 'sdf', 'seoij', 'sodifj');

$arr = array_remove($arr, 'sdf');

print_r($arr);

/*

Array

(

    [0] => '4'

    [1] => 'soeij'

    [2] => 'sodifj'

)

*/

Now in the example you gave, you are trying to apply this function to an array that is part of an object. I don't know how to help you on that since I don't know how the class of that object is structured.
But I hope this helps.
