    What do I replace the depreciated mysql_num_rows with ?

    Hi,

    I quite often use :

    PHP Code:
    $sql "SELECT page_id,page_type,cat_cd FROM pages WHERE assigned = 'n' ";
    $result mysql_query($sql)    or die("could not find SITE: $site_id"mysql_error());
    $num mysql_num_rows($result);

    if (
    $num ) { 
    I just noticed that the Manual says "mysql_num_rows - This extension is deprecated as of PHP 5.5.0"

    I write php in procedural style rather than OOP.

    What should I use instead of
    $num = mysql_num_rows($result);

    Thanks

    That one would be for statements, while from result you can use mysqli_num_rows. So it depends on if you are preparing a statement or querying directly.
    I should note that since there are two functions and you could do either statements or direct querying, you'd be better of using either the statement's get_result and pulling the mysqli_num_rows off of that, or even better, simply sticking to object oriented as both mysqli_stmt and mysqli_result contain a num_rows property on them.
    PHP Code:
    header('HTTP/1.1 420 Enhance Your Calm'); 
    Been gone for a few months, and haven't programmed in that long of a time. Meh, I'll wing it ;)

    depending on the case, SQL’s COUNT() function can be used to avoid the PHP row counting alltogether.
    The computer is always right. The computer is always right. The computer is always right. Take it from someone who has programmed for over ten years: not once has the computational mechanism of the machine malfunctioned.
