\nAvec l’arriv\u00e9e prochaine de la version 3.5 stable de joomla, il est temps de tester notre CMS favori avec PHP7. Jusqu’\u00e0 la version 3.4.8, Joomla n’est pas pr\u00eat pour cette version de PHP.<\/p>\n

Reinhard Kuchenbacker – Flickr<\/p>\n

Si on teste une distribution 3.4.8 avec PHP7, on r\u00e9cup\u00e8re cette Fatal error :
\nCannot use Joomla\\String\\String as String because ‘String’ is a special class name in \/libraries\/vendor\/joomla\/registry\/src\/Format\/Json.php on line 12
\nCeci a \u00e9t\u00e9 corrig\u00e9 dans la distribution 3.5. Et au moment o\u00f9 j’\u00e9cris, la version 3.5 Beta 2 est disponible ici ou ici. <\/p>\n

Serveurs et h\u00e9bergeurs
\nLes serveurs locaux
\n IMPORTANT : Comme vos sites Joomla sont encore fort probablement en J!3.4.8, il est \u00e9vident qu’il ne faut pas utiliser la m\u00eame pile que celle d\u00e9j\u00e0 install\u00e9e, \u00e9quip\u00e9e d’une version plus ancienne de PHP.
\nComme je travaille sur OSX, je m’appuie naturellement sur MAMP, qui a une fonctionnalit\u00e9 tr\u00e8s pratique : via les Pr\u00e9f\u00e9rences, on peut passer sans probl\u00e8me de PHP 5.xx \u00e0 PHP 7.xx et inversement, sans quitter l’appli.Il existe une version MAMP pour Windows, cependant, il est toujours recommand\u00e9 d’utiliser les installations natives (LAMP pour Linux, WAMP pour Windows, MAMP pour Mac, ou XAMPP pour une install cross-platforms.
\nDonc, pour tester PHP7, il faut d’abord que la pile\/stack utilis\u00e9e soit r\u00e9gl\u00e9e sur cette version de PHP.
\n Les piles les plus connues sont mises \u00e0 jour :
\n\u2022 XAMPP Installers https:\/\/www.apachefriends.org\/index.html
\n\u2022 EasyPHP http:\/\/www.easyphp.org\/
\n\u2022 WAMP http:\/\/www.wampserver.com\/
\n \u2022 MAMP https:\/\/www.mamp.info\/ <\/p>\n

La solution Bitnami
\nSi on ne veut pas toucher \u00e0 l’install serveur\/serveur MySQL d\u00e9j\u00e0 existante, super r\u00e9gl\u00e9e au petit poil, il existe toujours l’alternative Bitnami :
\n\u2022 Install WAMP Stack, Download WAMP Stack -> https:\/\/bitnami.com\/stack\/wamp\/installer
\n\u2022 Install MAMP Stack, Download MAMP Stack -> https:\/\/bitnami.com\/stack\/mamp\/installer
\n\u2022 Install LAMP Stack, Download LAMP Stack -> https:\/\/bitnami.com\/stack\/lamp\/installer
\nT\u00e9l\u00e9chargez celle \u00e9quip\u00e9e de PHP7.
\nLa pile Bitnami, contenue, peut parfaitement coexister avec n’importe quelle autre. Il suffit de ne pas les lancer en m\u00eame temps OU de changer les ports :
\n\u2022 Le port 3306 \u00e0 3307 pour MySQL
\n\u2022 Le port 8080 \u00e0 8081 pour le webserver
\n Nota : htdocs se trouve dans le dossier \/apache2\/ <\/p>\n

Les h\u00e9bergeurs
\nLes choses changent et les h\u00e9bergeurs principaux se sont mis \u00e0 jour d\u00e8s la sortie de PHP7.
\n\u2022 Test Joomla! 3.4 with PHP7 now (for advanced users) | 1&1 Community -> http:\/\/community.1and1.com\/joomla-3-4-php-7\/
\n\u2022 Que se cache-t-il sous le capot de PHP7 ? -> https:\/\/www.ovh.com\/fr\/a1948.php7-nouveautes-deja-le-moment-migrer
\n\u2022 O2swtich met en place php7 -> http:\/\/hebergeurs.xyz\/o2swtich-met-en-place-php7\/
\nTester J! 3.5 \u00e0 partir de J! 3.4.8
\nPour tester Joomla avec PHP7, il faut donc OBLIGATOIREMENT passer \u00e0 J!3.5.
\n 1) Mettre \u00e0 jour via la console admin
\nA partir du serveur en PHP 5.x, mettre \u00e0 jour par la console Admin :
\n IMPORTANT : Dans Configuration -> Serveur -> Rapport d’erreurs \u00e0 D\u00e9veloppement, bien entendu.
\nDans les param\u00e8tres de Mise \u00e0 jour de Joomla, r\u00e9gler Canal de mise \u00e0 jour \u00e0 Test.
\nApr\u00e8s Enregistrement, redirection vers cette page :<\/p>\n

J’ai d\u00fb tester un quinzaine de distributions et en g\u00e9n\u00e9ral, la mise \u00e0 jour se passe bien (hors extensions tierces). Il arrive que des erreurs SQL soient affich\u00e9es. Retournez simplement au panneau d’administration.
\nRien qui ne se r\u00e8gle par Extensions -> G\u00e9rer -> Base de donn\u00e9es -> Corriger. Il faut parfois activer la Correction une deuxi\u00e8me fois pour que le message attendu s’affiche (La structure des tables de la base de donn\u00e9es est \u00e0 jour.)
\n 2) Mettre \u00e0 jour comme une extension, via Extensions -> Installation. <\/p>\n

J! 3.5 et les extensions tierces
\nA l’heure o\u00f9 j’\u00e9cris, les extensions tierces les plus connues se mettent progressivement \u00e0 jour, quand c’est n\u00e9cessaire. Cependant, certains d\u00e9veloppeurs attendent la sortie de J! 3.5 stable pour adapter leur extension. Auquel cas, les erreurs les plus courantes sont celles-ci :
\nFatal error: Cannot use Joomla\\String\\String as String because ‘String’ is a special class name in \/libraries\/vendor\/joomla\/registry\/src\/Format\/Json.php on line 12
\nM\u00eame erreur que je signale plus haut pour J!3.4.8. Et perte d’acc\u00e8s au back-end. Pour r\u00e9cup\u00e9rer l’acc\u00e8s au back-end, j’ai remplac\u00e9 partout dans l’extension Joomla\\String\\String par Joomla\\String\\StringHelper.
\nOp\u00e9ration r\u00e9ussie et… d\u00e9sinstallation de l’extension coupable. Mais ce n’est pas une solution durable !
\nDeprecated: Methods with the same name as their class will not be constructors in a future version of PHP;
\nDans PHP7, la nom de la classe doit \u00eatre diff\u00e9rent du nom de la m\u00e9thode\/fonction. En ce cas, l’astuce (souffl\u00e9e par Peter van Westen, de nonumber.nl) est simple. Prenons l’exemple d’un module.
\nclass modMonmoduleMachin
\nassoci\u00e9 \u00e0 :
\npublic function modMonmoduleMachin (&$params)
\nLa correction :
\npublic function __construct (&$params)
\nCette modification r\u00e9tablit la fonctionnalit\u00e9 de l’extension sous PHP 7 et \u00e9vite les Warning(s). Mais encore une fois, laissons aux d\u00e9veloppeurs le soin d’adapter leur travail aux conditions requises par PHP7.
\nArray to string conversion
\nIci, juste une Notice. Mais l’acc\u00e8s au back-end peut \u00eatre perturb\u00e9. La correction :
\nif (isset($node->$nodes[$i]))
\ndevient
\nif (isset($node->{$nodes[$i]}))
\n R\u00e9sultat des courses
\nCe sont les principales erreurs que j’ai rencontr\u00e9es. Vous en rencontrerez certainement d’autres, surtout si le\/les d\u00e9veloppeur(s) des extensions n’ont pas mis \u00e0 jour depuis longtemps.
\n{loadposition pub-j3pour-tous}
\nConclusion
\nLe chemin de la mise \u00e0 niveau vers PHP7 n’est pas sem\u00e9 de roses, mais c’est jouable car J!3.5.x (hors extensions) est param\u00e9tr\u00e9 pour cette version de PHP. Je recommande, pour le moment, et m\u00eame quand J!3.5 Stable sortira, de proc\u00e9der avec pr\u00e9caution, et pas \u00e0 pas, en installant d’abord le package puis, progressivement vos extensions sur des sites test, que ce soit en local ou en distant. J’ai un site test qui tourne en PHP7 sur 1&1, pas de souci jusqu’\u00e0 maintenant.
\nAvertissement
\nA ce jour, la sortie de J!3.5.0 Beta 3 est encore dans les tuyaux. Je trouve que c’est une belle version, avec un soin particulier apport\u00e9 \u00e0 l’am\u00e9lioration de l’affichage du back-end.<\/p>\n

\u00a0
\n PS : Joomla Beta 3 est sorti le 18 f\u00e9vrier et cette version de teste est disponible ici : https:\/\/github.com\/joomla\/joomla-cms\/releases\/tag\/3.5.0-beta3<\/p>\n","protected":false},"excerpt":{"rendered":"
