獲取從文本

Question

在具體數值我有它

a:2:{i:0;a:17:{s:8:"quantity";i:1;s:10:"product_id";i:5196;s:11:"category_id";s:3:"209";s:5:"price";d:1;s:3:"tax";s:5:"18.00";s:6:"tax_id";s:1:"1";s:11:"description";s:0:"";s:12:"product_name";s:4:"test";s:11:"thumb_image";s:0:"";s:3:"ean";s:0:"";s:10:"attributes";s:6:"a:0:{}";s:16:"attributes_value";a:0:{}s:6:"weight";s:6:"0.0000";s:9:"vendor_id";s:1:"0";s:5:"files";s:6:"a:0:{}";s:14:"freeattributes";s:6:"a:0:{}";s:25:"dependent_attr_serrialize";s:6:"a:0:{}";}i:1;a:17:{s:8:"quantity";i:1;s:10:"product_id";i:4617;s:11:"category_id";s:3:"211";s:5:"price";d:1200;s:3:"tax";s:5:"18.00";s:6:"tax_id";s:1:"1";s:11:"description";s:74:"Машка блуза,EXTERRA ГТЦ 1 спрат и CITY MALL 1спрат";s:12:"product_name";s:0:"";s:11:"thumb_image";s:42:"thumb_e069100cef8553637664fc695df55c66.JPG";s:3:"ean";s:0:"";s:10:"attributes";s:6:"a:0:{}";s:16:"attributes_value";a:0:{}s:6:"weight";s:6:"0.0000";s:9:"vendor_id";s:1:"0";s:5:"files";s:6:"a:0:{}";s:14:"freeattributes";s:6:"a:0:{}";s:25:"dependent_attr_serrialize";s:6:"a:0:{}";}} 

該值的餅乾，我需要閱讀的價值和得到任何數字，是在數5196的文本中的位置，正確的在「product_id」之後;一世： 。所以有人有一個想法我怎麼能得到數字5196使用PHP？

Answer 1

如果可能的話，我會非常反對直接使用序列化數據。相反，我會使用unserialize反序列化數據，然後從結果數組中獲取值。

$data = 'a:2:{i:0;a:17:{s:8:"quantity";i:1;s:10:"product_id";i:5196...'; 
$rslt = unserialize($data); 

echo $rslt[0]["product_id"];

Answer 2

$str = 'a:2:{i:0;a:17:{s:8:"quantity";i:1;s:10:"product_id";i:5196;s:11:"category_id";s:3:"209";s:5:"price";d:1;s:3:"tax";s:5:"18.00";s:6:"tax_id";s:1:"1";s:11:"description";s:0:"";s:12:"product_name";s:4:"test";s:11:"thumb_image";s:0:"";s:3:"ean";s:0:"";s:10:"attributes";s:6:"a:0:{}";s:16:"attributes_value";a:0:{}s:6:"weight";s:6:"0.0000";s:9:"vendor_id";s:1:"0";s:5:"files";s:6:"a:0:{}";s:14:"freeattributes";s:6:"a:0:{}";s:25:"dependent_attr_serrialize";s:6:"a:0:{}";}i:1;a:17:{s:8:"quantity";i:1;s:10:"product_id";i:4617;s:11:"category_id";s:3:"211";s:5:"price";d:1200;s:3:"tax";s:5:"18.00";s:6:"tax_id";s:1:"1";s:11:"description";s:74:"Машка блуза,EXTERRA ГТЦ 1 спрат и CITY MALL 1спрат";s:12:"product_name";s:0:"";s:11:"thumb_image";s:42:"thumb_e069100cef8553637664fc695df55c66.JPG";s:3:"ean";s:0:"";s:10:"attributes";s:6:"a:0:{}";s:16:"attributes_value";a:0:{}s:6:"weight";s:6:"0.0000";s:9:"vendor_id";s:1:"0";s:5:"files";s:6:"a:0:{}";s:14:"freeattributes";s:6:"a:0:{}";s:25:"dependent_attr_serrialize";s:6:"a:0:{}";}}'; 
$ar = explode(";",$str); 
$ar2 = explode(":",$ar[4]); 
print_r($ar2[1]); 

Answer 3

使用一個正則表達式：

$cookie = 'value from your post'; 
preg_match('/.*"product_id";i:([^;]+)/', $cookie, $matches); 
$product_id = $matches[1]; 

Answer 4

該字符串是一個序列化的對象。如果你反序列化它，你可以遍歷它並找到具有product_id = 5196的數組，然後按照你的意願進行操作。得到它的其他值：

$str = 'a:2:{i:0;a:17:{s:8:"quantity";i:1;s:10:"product_id";i:5196;s:11:"category_id";s:3:"209";s:5:"price";d:1;s:3:"tax";s:5:"18.00";s:6:"tax_id";s:1:"1";s:11:"description";s:0:"";s:12:"product_name";s:4:"test";s:11:"thumb_image";s:0:"";s:3:"ean";s:0:"";s:10:"attributes";s:6:"a:0:{}";s:16:"attributes_value";a:0:{}s:6:"weight";s:6:"0.0000";s:9:"vendor_id";s:1:"0";s:5:"files";s:6:"a:0:{}";s:14:"freeattributes";s:6:"a:0:{}";s:25:"dependent_attr_serrialize";s:6:"a:0:{}";}i:1;a:17:{s:8:"quantity";i:1;s:10:"product_id";i:4617;s:11:"category_id";s:3:"211";s:5:"price";d:1200;s:3:"tax";s:5:"18.00";s:6:"tax_id";s:1:"1";s:11:"description";s:74:"Машка блуза,EXTERRA ГТЦ 1 спрат и CITY MALL 1спрат";s:12:"product_name";s:0:"";s:11:"thumb_image";s:42:"thumb_e069100cef8553637664fc695df55c66.JPG";s:3:"ean";s:0:"";s:10:"attributes";s:6:"a:0:{}";s:16:"attributes_value";a:0:{}s:6:"weight";s:6:"0.0000";s:9:"vendor_id";s:1:"0";s:5:"files";s:6:"a:0:{}";s:14:"freeattributes";s:6:"a:0:{}";s:25:"dependent_attr_serrialize";s:6:"a:0:{}";}}'; 
$unserialObj = unserialize($str); 
foreach($unserialObj as $item) { 
    if($item['product_id'] == 5196) { 
     echo $item['cateogry_id'] . ', '; 
     echo $item['price']; 
     //etc 
    } 
}
