php remove object from array of objects

Question

I'm trying to remove an object from an array of objects by its' index. Here's what I've got so far, but i'm stumped.

$index = 2;

$objectarray = array(
0=>array('label'=>'foo', 'value'=>'n23'),
1=>array('label'=>'bar', 'value'=>'2n13'),
2=>array('label'=>'foobar', 'value'=>'n2314'),
3=>array('label'=>'barfoo', 'value'=>'03n23')
);

//I've tried the following but it removes the entire array.
foreach ($objectarray as $key => $object) {
 if ($key == $index) {
   array_splice($object, $key, 1);
   //unset($object[$key]); also removes entire array.
 }
}

Any help would be appreciated.

Updated Solution

 array_splice($objectarray, $index, 1); //array_splice accepts 3 parameters 
    //(array, start, length) removes the given array and then normalizes the index
    //OR 
    unset($objectarray[$index]); //removes the array at given index
    $reindex = array_values($objectarray); //normalize index
    $objectarray = $reindex; //update variable 

Solution 1

    array_splice($objectarray, $index, 1); 
    //array_splice accepts 3 parameters (array, start, length) and removes the given 
    //array and then normalizes the index
    //OR 
    unset($objectarray[$index]); //removes the array at given index
    $reindex = array_values($objectarray); //normalize index
    $objectarray = $reindex; //update variable

Solution 2

You have to use the function unset on your array.

So its like that:

<?php

$index = 2;

$objectarray = array(
    0 => array('label' => 'foo', 'value' => 'n23'),
    1 => array('label' => 'bar', 'value' => '2n13'),
    2 => array('label' => 'foobar', 'value' => 'n2314'),
    3 => array('label' => 'barfoo', 'value' => '03n23')
);
var_dump($objectarray);
foreach ($objectarray as $key => $object) {
    if ($key == $index) {
        unset($objectarray[$index]);
    }
}

var_dump($objectarray);
?>

Remember, your array will have odd indexes after that and you must (if you want) reindex it.

$foo2 = array_values($objectarray);

Solution 3

in that case you won't need that foreach just unset directly

unset($objectarray[$index]);
