So here is my code:
<?php $arr = array(array(2 => 5), array(3 => 4), array(7 => 10)); foreach ($arr as $v) { $k = key($v); if ($k > 5) { // unset this element from $arr array } } print_r($arr); // now I would like to get the array without array(7 => 10) member As you can see, I start with an array of single key => value arrays, I loop through this array and get a key of the current element (which is a single item array).
I need to unset elements of the array with key higher than 5, how could I do that? I might also need to remove elements with value less than 50 or any other condition. Basically I need to be able to get a key of the current array item which is itself an array with a single item.

Use unset() function to remove array elements in a foreach loop. The unset() function is an inbuilt function in PHP which is used to unset a specified variable. The behavior of this function depends on different things.
To remove element from array in forEach loop with JavaScript, we can use the array splice method. const review = ["a", "b", "c", "b", "a"]; review. forEach((item, index, arr) => { if (item === "a") { arr. splice(index, 1); } });
The program needs access to the iterator in order to remove the current element. The for-each loop hides the iterator, so you cannot call remove . Therefore, the for-each loop is not usable for filtering.
Using unset() Function: The unset() function is used to remove element from the array. The unset function is used to destroy any other variable and same way use to delete any element of an array. This unset command takes the array key as input and removed that element from the array.
foreach($arr as $k => $v) { if(key($v) > 5) { unset($arr[$k]); } } If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
