SQL Like不工作字符串在php mysql中包含单引号

Question

SQL LIKE is not working when string contains single quote ',
Below is my php code

  $keysearch = "St.Joseph's"; // Searching keyword containing single quotes
  $sql =mysqli_query("select id,name from tbl where name LIKE '%$keysearch%'");

It returns no result,
How can I search a string contain single quotes?
Is there any effective operator except 'LIKE' for comparing single quotes value in DB?

Answer 1

Use addslashes() function of PHP as below,

$sql =mysqli_query($con,"select id,name from tbl where name LIKE '%".addslashes($keysearch)."%'");
