如何在mySQL中的REGEX中添加PHP变量

我的代码就像这样

SELECT count(product_id) as totalCount FROM ref_products WHERE misc REGEXP '(.*\"level_id\":\'".$course_level_id."'\.*)'     

Answer 1

假设您使用双引号字符串（“）：

$sql = "SELECT count(product_id) as totalCount FROM ref_products WHERE misc REGEXP '(.*\"level_id\":\'".$course_level_id."'.*)'";

假设您使用单引号字符串（'）：

$sql = 'SELECT count(product_id) as totalCount FROM ref_products WHERE misc REGEXP \'(.*\"level_id\":'.$course_level_id.'.*)\'';

Answer 2

感谢所有人的时间和时间。努力。这是我找到的正确答案。请检查

SELECT count(product_id) as totalCount FROM ref_products WHERE misc REGEXP '(.*\"level_id\":$course_level_id.*)'

Answer 3

SELECT count(product_id) as totalCount FROM ref_products WHERE misc REGEXP '(.*"level_id":"'.$course_level_id.'".*)'
