Problemas Com Array_search

[danielpc]

Ae pessoal, é o seguinte: Não sei o que está acontecendo com o código abaixo:

<?php

$nome = array("ABC","ADE");

$b = array_search("E",$nome);

echo "<p>".$b."</p>";

?>

Ele deveria escrever <p>1</p> porque 1 é o índice da array $nome que contém "E", mas tá escrevendo <p></p>

alguém sabe o que pode ser?

[Error404]

A função array_search() não vai procurar dentro dos valores, cara, ela só vai ver se tem um valor que casa com aquele.

Faz um teste, põe pra procurar "ADE" ao invés de "E". Deve funcionar...

[danielpc]

Deu certo mesmo. Mas você não conhece alguma função que procura uma substring em uma string?

[Error404]

Hmm... não...

Você vai ter que montar uma que faça isso.

Com um foreach() e umas funções de procura em strings você consegue
