在 Mysql 表格中插入变量不工作
原标题:insert variable into mysql table does not work

我试图在 Mysql 表格中插入变量, 但它不做我想要做的事( 没有错误, 它根本行不通 )

$string =  this is an example ;
mysql_query("insert into tablename (columnname) values ????");

谁能帮我在表格名中插入 $string ? 我试图替换 ????? <($string) , ("$string")。 , $string ,$string ,但所有这一切都没有在数据库中插入 $string 变量。

提前感谢!

最佳回答

您可以使用 " (一个逃避引用的引号)在查询中加入引号,例如:

$string =  this is an example ;
mysql_query("insert into tablename (columnname) values ("$string")");
问题回答

您忘记了引号 ( ), 您应该使用双字母的字符串分隔符 。

$string = "test abc";
mysql_query("insert into t (col) values ( $string )");
