You already know that you can add elements to an array using square bracket syntax.
For example:
$myArray[] ="new value"; $myArray["newKey"] ="new value";
This syntax is fine for simple scenarios.
PHP has five useful functions that you can use to add and remove elements:
| Function | Description |
|---|---|
| array_unshift() | Adds one or more new elements to the start of an array |
| array_shift() | Removes the first element from the start of an array |
| array_push() | Adds one or more new elements to the end of an array |
| array_pop() | Removes the last element from the end of an array |
| array_splice() | Removes element(s) from and/or adds element(s) to any point in an array |
