In order to remove an element from an array, we can use unset() function which removes the element from an array and then use array_values() function which indexes the array numerically automatically.
Function Used:
-
unset(): This function unsets a given variable.
Syntax:void unset ( mixed $var [, mixed $... ] )
-
array_values(): This function returns all the values from the array and indexes the array numerically.
Syntax:array array_values ( array $array )
Example 1:
<?php $arr1 = array (
'geeks' , // [0]
'for' , // [1]
'geeks' // [2]
); // remove item at index 1 which is 'for' unset( $arr1 [1]);
// Print modified array var_dump( $arr1 );
// Re-index the array elements $arr2 = array_values ( $arr1 );
// Print re-indexed array var_dump( $arr2 );
?> |
Output:
array(2) { [0]=> string(5) "geeks" [2]=> string(5) "geeks" } array(2) { [0]=> string(5) "geeks" [2]=> string(5) "geeks" }
We can also use array_splice() function which removes a portion of the array and replaces it with something else.
Example 2:
<?php $arr1 = array (
'geeks' , // [0]
'for' , // [1]
'geeks' // [2]
); // remove item at index 1 which is 'for' array_splice ( $arr1 , 1, 1);
// Print modified array var_dump( $arr1 );
?> |
Output:
array(2) { [0]=> string(5) "geeks" [1]=> string(5) "geeks" }
