Bonjour,
J'ai un petit souci avec la fonction in_array().
Tout d'abord voici le tableau $T:

Array ( [0] => 0 [1] => 20004 [2] => 20005 [3] => 20101 [4] => 20107 [5] => 20108 [6] => 20109 [7] => 21007 [8] => 22102 [9] => 22103 [10] => 22202 [11] => 22206 [12] => 22207 [13] => 22307 [14] => 22311 [15] => 22312 [16] => 22403 [17] => 22503 [18] => 22705 [19] => 22706 [20] => 22707 [21] => 22708 [22] => 23008 [23] => 23009 [24] => 23010 [25] => 23011 [26] => 23105 [27] => 23106 [28] => 23203 [29] => 23302 [30] => 23304 [31] => 23406 [32] => 23407 [33] => 23409 [34] => 23410 [35] => 24002 [36] => 24004 [37] => 24005 [38] => 25001 [39] => 25003 [40] => 25004 [41] => 25005 [42] => 25204 [43] => 25205 [44] => 25206 [45] => 25207 [46] => 25209 [47] => 25401 [48] => 25407 [49] => 25408 [50] => 25508 [51] => 25509 [52] => 25511 [53] => 25512 [54] => 25514 [55] => 31101 [56] => 31209 [57] => 31305 [58] => 31306 [59] => 31406 [60] => 32103 [61] => 32204 [62] => 32206 [63] => 32207 [64] => 32318 [65] => 32320 [66] => 32321 [67] => 32322 [68] => 32323 [69] => 32324 [70] => 32406 [71] => 33102 [72] => 33104 [73] => 33105 [74] => 33203 [75] => 33414 [76] => 33415 [77] => 33602 [78] => 34301 [79] => 34302 )

Celui-ci me sert à vérifier une données issue de la base. J'effectue une requete de type select et je récupère une données $data. Puis je vérifie à chaque itération que cette donnée $data est présente dans le tableau $T.
Pour vérifier la valeur de la fonction in_array je lance le code suivant à chaque itération:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
5
6
 
echo"\$data = $data<br>";
print_r($T);
echo"<br>";
echo"in_array(\$data = ,\$T) = ".in_array($data = ,$T);
echo"<br>";

Voici le début de l'affichage (3 premières itérations):

$data = 32323
Array ( [0] => 0 [1] => 20004 [2] => 20005 [3] => 20101 [4] => 20107 [5] => 20108 [6] => 20109 [7] => 21007 [8] => 22102 [9] => 22103 [10] => 22202 [11] => 22206 [12] => 22207 [13] => 22307 [14] => 22311 [15] => 22312 [16] => 22403 [17] => 22503 [18] => 22705 [19] => 22706 [20] => 22707 [21] => 22708 [22] => 23008 [23] => 23009 [24] => 23010 [25] => 23011 [26] => 23105 [27] => 23106 [28] => 23203 [29] => 23302 [30] => 23304 [31] => 23406 [32] => 23407 [33] => 23409 [34] => 23410 [35] => 24002 [36] => 24004 [37] => 24005 [38] => 25001 [39] => 25003 [40] => 25004 [41] => 25005 [42] => 25204 [43] => 25205 [44] => 25206 [45] => 25207 [46] => 25209 [47] => 25401 [48] => 25407 [49] => 25408 [50] => 25508 [51] => 25509 [52] => 25511 [53] => 25512 [54] => 25514 [55] => 31101 [56] => 31209 [57] => 31305 [58] => 31306 [59] => 31406 [60] => 32103 [61] => 32204 [62] => 32206 [63] => 32207 [64] => 32318 [65] => 32320 [66] => 32321 [67] => 32322 [68] => 32323 [69] => 32324 [70] => 32406 [71] => 33102 [72] => 33104 [73] => 33105 [74] => 33203 [75] => 33414 [76] => 33415 [77] => 33602 [78] => 34301 [79] => 34302 )

Comme vous pouvez le constatez, la fonction in_array ne retourne aucun résultat alors que la 1ère valeur de $data est bien présente dans la liste des valeurs du tableau $T.
Pourriez-vous me dire pourquoi cette fonction ne retourne rien?

Merci

PS : in_array('32323 ' ,$T) retourne comme valeur : 1

Bonjour,

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

in_array($data = ,$T)

A quoi sert le signe = derrière $data?????

[nicoaix]

C'est juste une faute de frappe...
Voilà c'est modifié.

[Mr N.]

pourrais-tu utiliser var_dump au lieu de print_r ?

[Mr N.]

et faire un var_dump($data) également

[nicoaix]

le var_dump à la place du print_r donne:

array(80) { [0]=> string(1) "0" [1]=> string(5) "20004" [2]=> string(5) "20005" [3]=> string(5) "20101" [4]=> string(5) "20107" [5]=> string(5) "20108" [6]=> string(5) "20109" [7]=> string(5) "21007" [8]=> string(5) "22102" [9]=> string(5) "22103" [10]=> string(5) "22202" [11]=> string(5) "22206" [12]=> string(5) "22207" [13]=> string(5) "22307" [14]=> string(5) "22311" [15]=> string(5) "22312" [16]=> string(5) "22403" [17]=> string(5) "22503" [18]=> string(5) "22705" [19]=> string(5) "22706" [20]=> string(5) "22707" [21]=> string(5) "22708" [22]=> string(5) "23008" [23]=> string(5) "23009" [24]=> string(5) "23010" [25]=> string(5) "23011" [26]=> string(5) "23105" [27]=> string(5) "23106" [28]=> string(5) "23203" [29]=> string(5) "23302" [30]=> string(5) "23304" [31]=> string(5) "23406" [32]=> string(5) "23407" [33]=> string(5) "23409" [34]=> string(5) "23410" [35]=> string(5) "24002" [36]=> string(5) "24004" [37]=> string(5) "24005" [38]=> string(5) "25001" [39]=> string(5) "25003" [40]=> string(5) "25004" [41]=> string(5) "25005" [42]=> string(5) "25204" [43]=> string(5) "25205" [44]=> string(5) "25206" [45]=> string(5) "25207" [46]=> string(5) "25209" [47]=> string(5) "25401" [48]=> string(5) "25407" [49]=> string(5) "25408" [50]=> string(5) "25508" [51]=> string(5) "25509" [52]=> string(5) "25511" [53]=> string(5) "25512" [54]=> string(5) "25514" [55]=> string(5) "31101" [56]=> string(5) "31209" [57]=> string(5) "31305" [58]=> string(5) "31306" [59]=> string(5) "31406" [60]=> string(5) "32103" [61]=> string(5) "32204" [62]=> string(5) "32206" [63]=> string(5) "32207" [64]=> string(5) "32318" [65]=> string(5) "32320" [66]=> string(5) "32321" [67]=> string(5) "32322" [68]=> string(5) "32323" [69]=> string(5) "32324" [70]=> string(5) "32406" [71]=> string(5) "33102" [72]=> string(5) "33104" [73]=> string(5) "33105" [74]=> string(5) "33203" [75]=> string(5) "33414" [76]=> string(5) "33415" [77]=> string(5) "33602" [78]=> string(5) "34301" [79]=> string(5) "34302" }

[Mr N.]

et pour $data ?

[nicoaix]

Je viens de trouver le problème. C'est tout con... C'est juste que les données que je sors de la base sous SQL Server contiennent 10 caractères maximum et lorsque ce champ contient par exemple que 5 caractères, il est complété avec des espaces.
Php comparait donc, par exemple "32323 " avec le "32323" contenu dans le tableau $T.
Merci pour votre aide, je pense que le var_dump m'a bien mis sur la voie.
