用PHP将双引号放在mysql字符串中

Question

我在PHP中有这个代码：

$_pagi_sql='SELECT * FROM programas WHERE MATCH(titulo, texto,pais) AGAINST ('"$criterio"' IN BOOLEAN MODE) AND operador=34 And validez >= NOW()';

我想把这个字符串放在变量$ _pagi_sql：

中

SELECT * FROM programas WHERE MATCH(titulo, texto,pais) AGAINST ('"STH"' IN BOOLEAN MODE) AND operador=34 And validez >= NOW()

但是双引号没有正确存储在变量$ _pagi_sql

中

怎么做？

Answer 1

您可以在单引号前添加斜杠来输入双引号。

$_pagi_sql='SELECT * FROM programas WHERE MATCH(titulo, texto,pais) AGAINST (\'"$criterio"\' IN BOOLEAN MODE) AND operador=34 And validez >= NOW()';

Answer 2

用双引号替换右手柄侧的单引号：

$_pagi_sql="SELECT * FROM programas WHERE MATCH(titulo, texto,pais) AGAINST ('\"$criterio\"' IN BOOLEAN MODE) AND operador=34 And validez >= NOW()";

或者，摆脱引号，使用heredoc：

$_pagi_sql = <<<SQL
SELECT * FROM programas WHERE MATCH(titulo, texto,pais) AGAINST ('"$criterio"' IN BOOLEAN MODE) AND operador=34 And validez >= NOW()
SQL;
