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.
The array_keys() function returns an array containing the keys.
Answer: Use the PHP unset() Function If you want to delete an element from an array you can simply use the unset() function. The following example shows how to delete an element from an associative array and numeric array.
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.
Although an array in PHP is "a type that associates values to keys" and some say it's not possible to remove the keys, you might, in a sense, remove the keys from an array either replacing the keys or replacing the array with another array.
I suppose you would like to change the array to an array equivalent to an array initialized without explicit keys. For instance, you might have this array:
$arr = array(2 => 'a', 3 => 'b', 4 => 'c');
But you'd like it to be equivalent to:
$arr = array('a', 'b', 'c');
It's possible to do it using the function "array_values", like this:
$arr = array_values($arr);
Notice, though, the array still has keys: 0, 1, 2, and 3.
It's important to note that the integer keys are not the same as the array indexes. For instance, this piece of code:
<?php
$arr = array(3 => '', 4 => '', 1 => '', 2 => '');
foreach($arr as $k => $v):
echo "$k ";
endforeach;
will output:
3 4 1 2
The function "array_values" might be used to make sure the keys values and indexes are the same:
<?php
$arr = array(3 => '', 4 => '', 1 => '', 2 => '');
foreach(array_values($arr) as $k => $v):
echo "$k ";
endforeach;
// outputs: 0, 1, 2, 3
I explained how to "remove" the keys, but you might want to implement a class for the topics, make an interface for topic contents (animations, images, etc.) and check the SPL data structures.
