help for inserting value to the array...

cjung1021

Is anybody knows that how to insert value to existed array? For example, there is an array which has five valuables already. And I want to insert one value to the array position "0".

Please give me your help if you know how to do... Thanks. 🙂

$array[0] = 'value';

If I understand you right. you simply wanna replace the value in index 0 right?

If you want to add an element into beginning (and preserve everything) you can use array_push_with_a_twist()

function array_push_with_a_twist($array) {
	$array = array_reverse($array);
	array_push($array,'H');
	$array = array_reverse($array);
	return $array;
}

I know how to replace array value ... My question is howto insert a value to the array. Let's say... $a = array("hello", "good", "hi");

I want to insert the text "great" in the array position "0". Final output I am expecting is following:

array("great", "hello", "good", "hi");

I hope to get some help. Thanks....

I believe array_shift() also performs a stack-like push.

array_unshift() is what you are looking for I think...

bretticus

array_unshift($array, "great");

Bah, PHP library has too many functions, takes away all the fun 😛
