Delete Element from Array in PHP Programming

2:29 AMSaturday, February 1, 2014

Delete  element in PHP array:-  If we wish to delete an item or element from PHP array then we have three choices first is remove the element  from starting position ,second is remove the elements  from last position and third is remove the element at any desire position of an array. Here following code is showing that how to implement above three operations.

Remove the element from starting position: - This can be possible to use  array_shift() PHP function. Syntax of this method is follows:-

mixed array_shift(array array);
this can be understood with the help of following code.
Let we  have an array 
$name =array(“weilems”, “jon”,”jacob”);

If we want  to remove the first name from this array then we can use array_shift() function such that
 Array_shift($name);
After execute this statement the start index value of this array is removed and the index of next elements is decremented by 1 this can be use for associative array.

Remove the element from ending position: - This can be possible to use array_pop() PHP function. Syntax of this method is follows:-

mixed array_pop(array target_array) 
this can be understood with the help of following code.
Let we  have an array 
$name =array(“jack”,“jon”,”jackren”);

If we want  to remove the last name from this array then we can use array_pop() function such that
 Array_pop($name);
After execute this statement the last index value of this array is removed. And the array becomes $name =array(“jack”,“jon”);

Remove the element at any desire position:- This is possible by using PHP unset() method. The syntax of this method is follows:-

unset(mixed vriable);
for example let we have an array such that
$branch=array(“CS”,”IT”,EE”);

And we want to remeove IT branch from this array then we can use unset() function in following way.
Unset ($branch [1]);
After execute this statement value stored at first index of array $branch will be unset and removed.
