(PHP 4, PHP 5)
array_push вЂ” Push one or more elements onto the end of array
array_push() treats array as a stack, and pushes the passed variables onto the end of array . The length of array increases by the number of variables pushed. Has the same effect as:
$array = $var;
Returns the new number of elements in the array.
Example#1 array_push() example
$stack = array("orange", "banana");
array_push($stack, "apple", "raspberry");
The above example will output:
Array (  => orange  => banana  => apple  => raspberry )
Note: If you use array_push() to add one element to the array it's better to use $array = because in that way there is no overhead of calling a function.
Note: array_push() will raise a warning if the first argument is not an array. This differs from the $var behaviour where a new array is created.
