sql将文本字符串存储为“数组”答案

【问题标题】：sql stores text string as "Array"sql将文本字符串存储为“数组”
【发布时间】：2017-11-11 10:44:47
【问题描述】：

我发现了一个奇怪的错误，它只出现在我的许多表单中的一个中，每个表单都以相同的方式使用，但是$codering = ['RF-013.12']; 在我的表中存储“数组”？并且它旁边的字段应该是 18，但存储的值为 0。
我想我在这里遗漏了一些东西。有人可以查看我的代码吗？谢谢！

编码字段是文本 latin1_swedish_ci
了解prepared Statements以防止SQL注入
如果您启用错误报告并检查您的日志，我几乎可以保证您有“数组到字符串转换”错误。跨度>
您的错误是这样的：$codering = ['RF-013.12']; - 这是一个包含 1 个元素的数组，您可能需要 $codering = 'RF-013.12';。注意括号不见了。
"但是 $codering = ['RF-013.12']; 在我的表中存储 "Array"" - 这是正确的，这就是该语法的作用。 [] 是“数组”的语法。

【解决方案1】：

你可以改变这个：

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

到这里：

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

我认为在这种情况下您不需要将数组放入数据库中，因此请将数组变量更改为简单的字符串来解决您的问题

如果您想将数组插入数据库，我建议您使用 json_encode

例子：

json_encode($yourArray);

【解决方案2】：

这很正常。当你这样做时：

$codering = ['RF-013.12'];

等同于：

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

所以如果你尝试像字符串一样使用你的数组，php 写 array 代替。

如果你想存储 [something]（带有 [] 字符的字符串），你需要：

$codering = "[something]";

如果你真的需要存储一个数组，你可以序列化他。

例子：

serialize

string serialize ( mixed $value )

或

json_encode

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

【讨论】：

【解决方案3】：

这里是你创建的数组。 [] 是数组语法

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

你需要像这样传递字符串

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

【讨论】：

【解决方案4】：

也许，因为您将一个包含一个元素的数组传递给您的数据库。你的桌子的结构说明了什么？如果您尝试存储数组，请尝试在现有表上使用带有引用的外部表。

如果要将 RF-013.12 保存为字符串，只需使用 $codering = "RF-013.12";。如果您有一个以 RF-013.12 作为键的数组，请尝试引用该值。

问候。
