sql將文本字符串存儲爲「數組」

Question

我發現了一個奇怪的錯誤，它只出現在我的許多表單中的一箇中，每個表單都以相同的方式使用，但$codering = ['RF-013.12'];在我的表中存儲「Array」？和它旁邊的字段應該是18，但存儲值爲0.
我想我在這裏錯過了一些東西。有人可以查看我的代碼嗎？謝謝！

Answer 1

這很正常。當你這樣做：

$codering = array('RF-013.12'); 

因此，如果您嘗試使用您的陣列像串，PHP寫陣列代替：

$codering = ['RF-013.12']; 

爲相同。

如果你想儲存[東西]（帶[]字符的字符串），你需要：

$codering = "[something]"; 

如果你真的需要存儲陣列，您可以同時連載了他。

實施例：

serialize

string serialize (mixed $value) 

或

json_encode

string json_encode (mixed $value [, int $options = 0 [, int $depth = 512 ]]) 

Answer 2

你可以改變這一點：

$codering = ['RF-013.12']; 
$revisie = ['18']; 

這樣：

$codering = 'RF-013.12'; 
$revisie = '18'; 

我認爲你不需要陣列到你的數據庫在這種情況下，如此改變數組變成簡單的字符串來解決你的問題

如果你要插入一個數組我勸數據庫您使用 json_encode

例子：

json_encode($yourArray); 

Answer 3

這裏您創建陣列。 []是數組語法

$codering = ['RF-013.12']; 
$revisie = ['18']; 

你需要傳遞的字符串這樣

$codering = 'RF-013.12'; 
$revisie = '18'; 

Answer 4

也許，因爲你傳遞一個包含一個元素到你的數據庫的數組。 你的桌子的結構說什麼？ 如果您嘗試存儲數組，請嘗試在現有表上使用帶有引用的外部表。

如果要將RF-013.12保存爲字符串，只需使用$codering = "RF-013.12";即可。 如果您有一個RF-013.12作爲密鑰的陣列，請嘗試引用該值。
