<function>array_push</function> treats
|
|
<parameter>array</parameter> as a stack, and pushes the passed
|
|
variables onto the end of <parameter>array</parameter>. The
|
|
length of <parameter>array</parameter> increases by the number of
|
|
variables pushed. Has the same effect as:

repeated for each <parameter>var</parameter>.

Returns the new number of elements in the array.

|
|
If you use <function>array_push</function> to add one element to the
|
|
array it's better to use <literal>$array[] = </literal> because in that
|
|
way there is no overhead of calling a function.
|
|
</simpara>

|
</note>
|
|
<note>
|
|
<simpara>
|
|
<function>array_push</function> will raise a warning if the first
|
|
argument is not an array. This differs from the
|
|
<literal>$var[]</literal> behaviour where a new array is created.
