PHP反序列化和访问数组

Question

我有一些复杂的数据需要序列化。

当我尝试对其进行反序列化时，得到的结果是：

bool(false) bool(false) bool(false) bool(false) bool(false) bool(false) bool(false) bool(false) bool(false) bool(false)...etc...

这是序列化后的字符串：

a:6:{i:0;a:10:{s:6:"ItemID";s:1:"1";s:11:"ItemEventID";s:1:"1";s:7:"ItemCat";s:3:"REG";s:8:"ItemName";s:21:"Inscrição Masculina";s:8:"ItemCost";s:4:"9.00";s:12:"ItemCurrency";s:3:"EUR";s:8:"ItemFree";s:1:"N";s:9:"ItemStart";s:9:"2013-1-12";s:7:"ItemEnd";s:8:"2013-4-7";s:7:"ItemQty";s:1:"1";}i:1;a:10:{s:6:"ItemID";s:1:"3";s:11:"ItemEventID";s:1:"1";s:7:"ItemCat";s:3:"REG";s:8:"ItemName";s:36:"Inscrição Feminina (oferta jersey)";s:8:"ItemCost";s:4:"9.00";s:12:"ItemCurrency";s:3:"EUR";s:8:"ItemFree";s:1:"N";s:9:"ItemStart";s:9:"2013-1-12";s:7:"ItemEnd";s:8:"2013-4-7";s:7:"ItemQty";s:1:"0";}i:2;a:10:{s:6:"ItemID";s:1:"4";s:11:"ItemEventID";s:1:"1";s:7:"ItemCat";s:3:"MLS";s:8:"ItemName";s:8:"Almoços";s:8:"ItemCost";s:4:"5.00";s:12:"ItemCurrency";s:3:"EUR";s:8:"ItemFree";s:1:"N";s:9:"ItemStart";s:9:"2013-1-12";s:7:"ItemEnd";s:8:"2013-4-7";s:7:"ItemQty";s:1:"0";}i:3;a:10:{s:6:"ItemID";s:2:"13";s:11:"ItemEventID";s:1:"1";s:7:"ItemCat";s:3:"MDS";s:8:"ItemName";s:16:"Jersey Masculino";s:8:"ItemCost";s:5:"10.00";s:12:"ItemCurrency";s:3:"EUR";s:8:"ItemFree";s:1:"N";s:9:"ItemStart";s:9:"2013-1-13";s:7:"ItemEnd";s:8:"2013-4-7";s:7:"ItemQty";s:1:"0";}i:4;a:10:{s:6:"ItemID";s:2:"14";s:11:"ItemEventID";s:1:"1";s:7:"ItemCat";s:3:"MDS";s:8:"ItemName";s:35:"Calção Ciclismo Alusivo ao Evento";s:8:"ItemCost";s:5:"28.00";s:12:"ItemCurrency";s:3:"EUR";s:8:"ItemFree";s:1:"N";s:9:"ItemStart";s:9:"2013-1-16";s:7:"ItemEnd";s:8:"2013-4-7";s:7:"ItemQty";s:1:"0";}i:5;a:10:{s:6:"ItemID";s:2:"11";s:11:"ItemEventID";s:1:"1";s:7:"ItemCat";s:3:"DSC";s:8:"ItemName";s:72:"Desconto de 1€ por ter licença de Competição/Betetista/Cicloturista";s:8:"ItemCost";s:5:"-1.00";s:12:"ItemCurrency";s:3:"EUR";s:8:"ItemFree";s:1:"N";s:9:"ItemStart";s:9:"2013-1-13";s:7:"ItemEnd";s:8:"2013-4-7";s:7:"ItemQty";s:1:"0";}}

我试着用这个：

$temp = unserialize(utf8_encode($dataArr[6]));
var_dump($temp);

在这个站点中，当我粘贴我的序列化数据时，一切都很好：

谢谢

您必须删除utf8_encode。

如果$dataArr是您的字符串，那么在访问数组中的变量之前必须对其进行反序列化。

$dataArr = 'a:6:{i:0;a:10:{s:6:"ItemID";s:1:"1";s:11:"ItemEventID";s:1:"1";s:7:"ItemCat";s:3:"REG";s:8:"ItemName";s:21:"Inscrição Masculina";s:8:"ItemCost";s:4:"9.00";s:12:"ItemCurrency";s:3:"EUR";s:8:"ItemFree";s:1:"N";s:9:"ItemStart";s:9:"2013-1-12";s:7:"ItemEnd";s:8:"2013-4-7";s:7:"ItemQty";s:1:"1";}i:1;a:10:{s:6:"ItemID";s:1:"3";s:11:"ItemEventID";s:1:"1";s:7:"ItemCat";s:3:"REG";s:8:"ItemName";s:36:"Inscrição Feminina (oferta jersey)";s:8:"ItemCost";s:4:"9.00";s:12:"ItemCurrency";s:3:"EUR";s:8:"ItemFree";s:1:"N";s:9:"ItemStart";s:9:"2013-1-12";s:7:"ItemEnd";s:8:"2013-4-7";s:7:"ItemQty";s:1:"0";}i:2;a:10:{s:6:"ItemID";s:1:"4";s:11:"ItemEventID";s:1:"1";s:7:"ItemCat";s:3:"MLS";s:8:"ItemName";s:8:"Almoços";s:8:"ItemCost";s:4:"5.00";s:12:"ItemCurrency";s:3:"EUR";s:8:"ItemFree";s:1:"N";s:9:"ItemStart";s:9:"2013-1-12";s:7:"ItemEnd";s:8:"2013-4-7";s:7:"ItemQty";s:1:"0";}i:3;a:10:{s:6:"ItemID";s:2:"13";s:11:"ItemEventID";s:1:"1";s:7:"ItemCat";s:3:"MDS";s:8:"ItemName";s:16:"Jersey Masculino";s:8:"ItemCost";s:5:"10.00";s:12:"ItemCurrency";s:3:"EUR";s:8:"ItemFree";s:1:"N";s:9:"ItemStart";s:9:"2013-1-13";s:7:"ItemEnd";s:8:"2013-4-7";s:7:"ItemQty";s:1:"0";}i:4;a:10:{s:6:"ItemID";s:2:"14";s:11:"ItemEventID";s:1:"1";s:7:"ItemCat";s:3:"MDS";s:8:"ItemName";s:35:"Calção Ciclismo Alusivo ao Evento";s:8:"ItemCost";s:5:"28.00";s:12:"ItemCurrency";s:3:"EUR";s:8:"ItemFree";s:1:"N";s:9:"ItemStart";s:9:"2013-1-16";s:7:"ItemEnd";s:8:"2013-4-7";s:7:"ItemQty";s:1:"0";}i:5;a:10:{s:6:"ItemID";s:2:"11";s:11:"ItemEventID";s:1:"1";s:7:"ItemCat";s:3:"DSC";s:8:"ItemName";s:72:"Desconto de 1€ por ter licença de Competição/Betetista/Cicloturista";s:8:"ItemCost";s:5:"-1.00";s:12:"ItemCurrency";s:3:"EUR";s:8:"ItemFree";s:1:"N";s:9:"ItemStart";s:9:"2013-1-13";s:7:"ItemEnd";s:8:"2013-4-7";s:7:"ItemQty";s:1:"0";}}';

$temp = unserialize($dataArr);

//Now you can access every element with its index.
var_dump($temp[0]);
var_dump($temp[1]);
var_dump($temp[2]);
var_dump($temp[3]);
var_dump($temp[4]);
var_dump($temp[5]);
