    How do I solve database errors caused by quotes/apostrophes?

    Consider the following SQL statement:
    INSERT INTO articles SET title='The PHP Anthology';
    Perhaps the PHP script that made this query contained something like this:


    <?php
    $title = "The PHP Anthology";
    $sql = "INSERT INTO articles SET title='$title';";
    $result = mysql_query($sql, $dbConn);
    ?>
    No problem so far, but look what happens if we change the title:

    $title = "PHP's Greatest Hits";
    Notice the apostrophe in the title? When we place this in the SQL statement,
    the query MySQL receives will be as follows:

    INSERT INTO articles SET title='PHP's Greatest Hits';

    See the problem? When MySQL reads that statement, it will only get as far as
    this:

    INSERT INTO articles SET title='PHP'
    The rest of the statement will cause a syntax error and the query will fail. Its easy enough to avoid this problem when you write the title yourself, but what happens when your script gets the value from user input?

    Re: How do I solve database errors caused by quotes/apostrophes?

    I have moved my website to another host. The previous version of PHP was 5.2 and now it is 5.3 When I go to my website it shows an error and couldn't figure out what the problem is. Until I found an article on the Internet How to fix error "SyntaxError: Unexpected reserved word 'await' everything is described in detail there. I think this will help you if you cant figure something out like me.
