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" }
