php - php INSERT INTO database variable name

Question

When trying to use

$SomeTable = "SomeTable";
INSERT INTO "' . $SomeTable . '" SET ... 

instead of

INSERT INTO SomeTable SET ...

I am unsuccessful. Why am I unable to use a php variable to call a database name?

Answer 1

你需要使用这样的东西：

$SomeTable = "SomeTable";
$query = 'INSERT INTO `' . $SomeTable . '` SET ... ';

它使用 ` 字符而不是引号
