<function>array_push</function> considera <parameter>array</parameter>
|
|
como una pila, y apila las variables <parameter>values</parameter> al final de <parameter>array</parameter>.
|
|
La longitud del array <parameter>array</parameter> aumenta en consecuencia.
|
|
Esto tiene el mismo efecto que:

<programlisting role="php">

<![CDATA[
|
|
<?php

$array[] = $var;

</programlisting>

repetido para cada valor.

|
|
<note>
|
|
<simpara>
|
|
Si se utiliza la función <function>array_push</function> para añadir un
|
|
elemento a un array, es preferible reemplazarla por el operador
|
|
<literal>$array[] = </literal> que evita el paso por una función.
|
|
</simpara>
|
|
</note>
|
|
<note>
|
|
<simpara>
|
|
<function>array_push</function> emitirá una alerta si el primer argumento
|
|
no es un array. Esto difiere del comportamiento de
|
|
<literal>$var[]</literal> donde un nuevo array era creado, anteriormente a PHP 7.1.0.

Anteriormente, se requerían al menos dos parámetros.
