Question

i use mysql_real_escape_string php function for escape data recieved from a form. my code for recieve form data is :

$std_id     =   mysql_real_escape_string($_POST['std_id']);
$name       =   mysql_real_escape_string($_POST['name']);
$family     =   mysql_real_escape_string($_POST['family']);

for example if enter O’reilly string in name form field , this function work fine and my query done too.but when i go to mysql and my table , see that this string is inserted like O’reilly and not O\’reilly.
my query is :

$sql    =   "insert into student set 
            std_id  =   $std_id,
            name    =   '$name',
            family  =   '$family',
            ";

this happens when use addslashes() function too.

Answer 1

This is exactly what is supposed to happen. You want to insert the string O'reilly into the database, not O\'reilly, right?

The slashes merely tell MySQL that the next ' is supposed to be a literal apostrophe, and not the apostrophe/single quote denoting the end of the string.

PS: You might want to consider using PDO and prepared statements, which offer a much cleaner syntax.
