Expression régulière simple mais je bloque

[lambi521]

Bonjour à tous,

Pour faire simple, je dois trouver le dernier chiffre d'une série de chiffre séparés par un underscore :
$data = 52_103;

J'ai fait ceci :

preg_match("([0-9]{1,3})[^_]", $data, $matchs);

Mais ça ne fonctionne pas, quelqu'un peut m'aider ?

Il faut que ça fonctionne aussi si $data = 52 par exemple, donc pas de underscore dans $data

Pourquoi utiliser un regex pour ça ?

<span class="syntaxhtml"><br /><span class="syntaxdefault"><?php&nbsp;<br />$data&nbsp;</span><span class="syntaxkeyword">=&nbsp;</span><span class="syntaxstring">'52_42_80_103'</span><span class="syntaxkeyword">;<br />echo&nbsp;</span><span class="syntaxdefault">array_pop</span><span class="syntaxkeyword">(</span><span class="syntaxdefault">explode</span><span class="syntaxkeyword">(</span><span class="syntaxstring">'_'</span><span class="syntaxkeyword">,&nbsp;</span><span class="syntaxdefault">$data</span><span class="syntaxkeyword">));<br /></span><span class="syntaxdefault">?><br /></span></span>

Merci zeb pour le lien, j'ai refait un topic en expliquant plus "simplement"

@spout : merci pour ton code, je vais tester et je vous fait un retour. C'est sûr que ça prendra le dernier chiffre hein ?
Dsl d'insister mais les expressions régulières c'est vraiment pas mon truc !

Merci Spout, ça marche à la perfection, bonne idée le explode, pourquoi n'y ai-je pas pensé ?! A chaque fois tu me réponds en 2 lignes et ça marche toujours parfaitement, j'adore ! Dès que je suis millionnaire je t'embauche lol

Voici le code final qui traite mes URLs de catégories si ça peut aider quelqu'un qui passerais par là :
