La nouvelle mouture du PHP, version 4.0.4 vient d'arriver à l'instant même.
Au programme, ajout de nouvelles fonctions (is_null(), get_defined_functions(), get_defined_vars(), constant(), array_sum(), etc...) mais aussi le support CORBA, Ovrimos, et de la version 3.0 de Solid.
Et plein d'autres bonnes choses que je vous laisses découvrir par vous même. (notamment des corrections de bug assez nombreuses).

PS: Seul les sources sont disponibles pour l'instant. Les binaires devraient arriver très rapidement). PHP 4.0 NEWS

19 Dec 2000, Version 4.0.4
- Allow assigning a newly created object by reference. This is needed only if
your constructor makes other data structures reference the $this object (for
example, $GLOBALS["foobar"] =& $this;)
The new syntax is $obj =& new MyClass(); (Andi, Zend Engine)
- Allow for three expression types to be sent to functions which are requesting
the function argument to be passed by reference (only c. was previously
a. func(new myclass());
b. func(func2()); where func2() returns a reference, i.e. is defined as
function &func2(...)
c. func($var); where func() is defined as function func(&$var) {...}
You CAN'T count on any other expressions to be passable by reference.

  • # Licence ?

    Posté par . Évalué à 0.

    Sans vouloir lancer de polémique, c'est quoi la licence exacte ? (pas du GPL il me semble).

    Qu'est-ce qui nous garantie qu'on pourra utiliser php sans problème dans le futur sans voir à payer de droits (style ce qui pourrait arriver pour mp3) ?

    A ce que j'ai compris c'est OK pour php3 mais pas pour php4. C'est bien ça ?
    • [^] # Re: Licence ?

      Je viens de lire la licence. Ce n'est effectivement pas du GPL, mais rien ne m'a choqué.

      J'ai l'impression, mais d'autre te confirmetons ou t'infirmerons, que ça ressemble plus à du BSD qu'à du GPL.

        d'après la fsf http:\\ c'est du "free software" mais pas compatible avec la gpl car non-copyleft (contrairement à php 3)
        explication là
        (il y a le détail de plein de type de licence, c'est assez instructif)

        sinon la licence de php 4.0 se rapproche de celle de bsd . Voila l'explication des problèmes a utiliser une telle licence (différence entre licence copyleft et non-copyleft)

          là je répond à moi-même ;)
          Par contre j'apprécie vraiment les évolutions qu'il y a eu entre php 3 et php 4 (notament au niveau performance).
          Et pour vous quel sont les points les plus positifs/négatifs de php 3 et de php 4 ?
          êtes-vous passé de php3 à php4 ? sinon pourquoi ? (exemple -> support sybase bien buggé...)

          voili, voilo
        • [^] # Re: Licence ?

          PHP 4 est donc un logiciel libre, on est bien d'accord.

          Savoir si la BSD est meilleur ou moins bonne que la GPL n'a que peux d'intérêt. Les deux sont là, faut bien faire avec.
          • [^] # Re: Licence ?

            Posté par . Évalué à 0.

            La licence BSD n'est pas un license pour le libre, le code peut être diffusé comme ne pas l'être et surtout ne plus l'être.

            La licence BSD modifié est libre mais déconseillé car elle prète à confusion.

            Ha oui, la petite phrase qui tue
            >Les deux sont là, faut bien faire avec.
            M$ est là et faut bien faire avec.

              Python a partir de la 1.6b1

      L'alternative interessante en GPL c'est PERL/DBI.

      L'édition française de Perl DBI par Descartes et Tim Bunce est disponible aux editions O'Reilly - Si j'ai le temps, je vous poste une petite description du livre.

    C un peu off-topic, mais quelqu'un aurait déjà utilisé le support XML via php (juste lire/ecrire des fichiers) ? pourrait-on me donner un lien vers une intro du XML via php ?

    Je trouve que 404, c'est un très bon numéro de version pour un machin de page web.
