PHP de base : echo

Invité · 27/04/2014, 15h54

Bonjour.
les 2 lignes php ne sont pas lues par Wampserver. Je ne comprends pas quoi mettre après écho.
Dans le premier cas une chaine de caractères entre 2 apostrophes devrait être lu.
Dans le second une fonction n'a pas besoin de guillemets, ni d'apostrophe.
Pourquoi mon résultat n'est pas celui attendu ?
Merci de votre aide.

Bonjour.
Oui j'ai regardé. Un peu trop sans doute.
Merci de m'indiquer les énormités et surtout pourquoi ce sont des énormités.

Ton php n'a pas l'air d'être interprété, le code est syntaxiquement correct.

Pour vérifier si ton php est bien interprété, créer une page php vide et met y uniquement le code suivant :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

<?php phpinfo(); ?>

Les détails du serveur web doivent apparaître.

si tu est sous windows, vérifie que le fichier "basique_pHp.php" ne s'appelle pas en réalité "basique_pHp.php.txt" et que windows ne te cache pas "les extensions de fichiers connues"

Invité · 29/04/2014, 09h29

Bonjour.
C'est effectivement une erreur que j'ai déjà faite et que je referai probablement, mais là, je pense que si il y avait un problème d'extension, les balises HTML n'auraient pas été lues non plus et la phrase "Contenu de la page" n'apparaîtrat pas correctement dans le navigateur.
Il semble ici que seul le script php n'ait pas été lu. Probablement pour une raison évidente mais je débute et les évidences...
Alain.

var_dump($a);
?>

Un code PHP non interprété s'affiche en général en clair dans la page. Et visiblement, l'interprétation fonctionne vu que le phpinfo() t'a bien renvoyé les infos.
Comme te l'a suggéré mathieu, regarde la source de la page générée dans ton navigateur : il est possible que le code soit bien interprété, soit présent dans la page, mais non visible pour une quelconque raison de balises HTML.

C'est ce qu'il a fait. C'est bizarre, le code n'a pas l'air interprété... Et il ne s'affiche pas pour autant.

Invité · 29/04/2014, 20h13

Salut.
Donc c'est bien ce que j'ai envoyé et on constate que le php n'a pas été interprété ? Why ?

**jisig** · 30/04/2014, 12h38

Si il a été interpreté, mais mal dirait-on, je te conseille plutôt d'utiliser xampp (qui lui respecte la casse au passage, ce qui t'amènera moins de problème par la suite.)

**Celira** · 30/04/2014, 13h16

J'ai copié-collé ton code dans un fichier sur mon WampServer et ça fonctionne très bien

Si tu refais le même fichier sans les balises html, genre avec juste les echo, est-ce que ça fonctionne ?

Invité · 30/04/2014, 21h35

Bonjour et merci Celira.
Genre juste echo, ça marche...mais moi, je ne comprends plus rien.

On dirait que ton serveur n'accepte pas de php dans ta structure html

Essaie là dedans ça devrait aller sans problème.

Merci.
D'où l’intérêt du doctype.
