What is PHP array_push() Function?
If you want to add one or more elements to the end of an array, use array_push() function.
Syntax:
array_push(array, value1, value2, …)
Parameters:
The Function has 1 required parameter and 1 or more optional parameters-
array (Required): The input array
value1, value2,… (Optional): It specifies one or more elements (values) that you want to add. Values are separated by comma. As it is an optional parameter, if you omit this, PHP will not throw any error. See example 2.
Return Values:
It doesn’t return the modified array, but, it adds the elements that you supplied to the function to the end of the input array. The function returns the number of elements in the modified array. See example 4.
