13 - array_search - recherche dans un tableau multidimensionnel
in (PHP 5 >= 5.5.0) you don't have to write your own function to search through a multi dimensional array
ex :
$userdb=Array
(
(0) => Array
(
(uid) => '100',
(name) => 'Sandra Shush',
(url) => 'urlof100'
),
(1) => Array
(
(uid) => '5465',
(name) => 'Stefanie Mcmohn',
(pic_square) => 'urlof100'
),
(2) => Array
(
(uid) => '40489',
(name) => 'Michael',
(pic_square) => 'urlof40489'
)
);
simply u can use this
$key = array_search(40489, array_column($userdb, 'uid'));

59 - variables dynamiques (dont le nom est une variable)
(via HollandaisVolant)
Faire des variables dynamiques en JS.
Un trop dont je ne me sert jamais, mais là ouais.
// En gros, si t’as ça :
var variable = 'machin';
var machin = document.getElementById('id');
// on peut faire :
eval(variable).style.display = 'block';
// variable contient « machin ».
// en faisant le eval(), c’est comme si le contenu de "variable" devenait une variable. Ici, donc, le #id aura comme display un « block ».
// Pratique si on n’a pas envie de faire un « getElementById » pour 50 blocs à la fois, mais qu’on peut écrire dans un boucle avec ça.
Ça existe aussi en PHP :
$var = nombre;
$nombre = 137;
$$var = 42;

76 - Lire/écrire dans un fichier en compressant/décompressant en une instruction
#En PHP, il y a plusieurs moyens pour lire et écrire dans un fichier (fopen). De même pour en compresser son contenu (gzcompress).
#Seulement, vous pouvez vous simplifier la vie en utilisant UNE seule instruction pour stocker du contenu sous forme compressée :
file_put_contents("compress.zlib://$filename", $content);
#Ensuite, pour lire ce fichier compressé, UNE instruction également :
$content = file_get_contents("compress.zlib://$filename");
#"compress.zlib://" est en fait ce qu'on appelle un wrapper ; il en existe plusieurs autres en PHP. Celui-ci permet de dire que le fichier sera compressé grâce à la bibliothèque Zlib.
#ATTENTION : avec file_get_contents(), si la lecture échoue, il renvoie le booléen "false" ! Or, il est indispensable de bien tester le retour à l'aide de l'égalité de #type (=== ou !==), car si le fichier contient, par exemple, 0 et que vous testez avec l'égalité simple (== ou !=), alors il considérera que c'est faux, donc que la #lecture a échoué ! C'est normal : 0 == false (même valeur) mais 0 !== false (pas le même type) !
#Donc il faut tester comme suit : if ($content !== false) { //OK, do something... }
