## 例

`

     int array_push ( array &$array , mixed $var [, mixed $... ] )

`

## 説明

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:
<`?php$array[] = $var;?`>
repeated for each var. 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.

## 戻り値

Returns the new number of elements in the array.
