我有這樣的數(shù)組

array(2) { [0]=> object(stdClass)#20       (4) {            ["id"]=> string(1) "1"            ["name"]=> string(6) "robert"            ["height"]=> string(3) "165"            ["weight"]=> string(2) "81" } [1]=> object(stdClass)#21       (4) {            ["id"]=> string(1) "2"            ["name"]=> string(4) "mike"            ["height"]=> string(3) "175"            ["weight"]=> string(2) "69" } }

因此,我想更改數(shù)組值.

例如,我想更改[[height]]和[[weight]]的所有值.我將身高和體重按如下數(shù)字分類：

高度

1 = 150 ………. 170

2 = 171 ………. 190

重量

1 = 50 ……….. 70

2 = 71 ……….. 80

array(2) { [0]=> object(stdClass)#20       (4) {            ["id"]=> string(1) "1"            ["name"]=> string(6) "robert"            ["height"]=> string(1) "1"            ["weight"]=> string(1) "2" } [1]=> object(stdClass)#21       (4) {            ["id"]=> string(1) "2"            ["name"]=> string(4) "mike"            ["height"]=> string(1) "2"            ["weight"]=> string(1) "1" } }

我的數(shù)組是動態(tài)的,因此值可以隨時更改.當(dāng)然,[“ name”]不會改變,因為我沒有給出分類.您能幫我解決這個問題嗎？

解決方法:

給定您的示例數(shù)組為：

//example people array$people = [      //robert      (object)[            "id" =>"1",            "name"=> "robert",            "height" => "165",             "weight" => "79",            ],      //mike      (object)[        "id" => "2",        "name"=> "mike",        "height"=> "175",         "weight" =>"69",        ]  ];

您可以在稍作比較之后遍歷數(shù)組并修改每個對象.請注意,我不會檢查所有可能的范圍以保持簡潔(應(yīng)該再檢查幾下)

//walk the array array_walk($people, function($person){  //test height and assign category  if($person->height <= 190 && $person->height > 170)    $person->height = "2";  else    $person->height = "1";  //test weight and assign category  if($person->weight <= 80 && $person->weight > 70)    $person->weight = "2";  else    $person->weight = "1";});

可以產(chǎn)生期望的結(jié)果,您可以實時檢查"1", "name"=> "robert", "height" => "165", "weight" => "81", ], //mike (object)[ "id" => "2", "name"=> "mike", "height"=> "175", "weight" =>"69", ] ]; //walk the array array_walk($people, function($person){ //test height and assign category if($person->height <= 190="" &&="" $person-="">height > 170) $person->height = "2"; else $person->height = "1"; //test weight and assign category if($person->weight <= 80="" &&="" $person-="">weight > 70) $person->weight = "2"; else $person->weight = "1";}); print_r($people);" rel="nofollow">here(運行CTRL ENTER)
