Question

I am trying do multi-driver support for my Framework, which basically means I can use MySQL, MySQLi or PDO(MySQL) with ease.

So, let’s say I have an array of values I want to insert.

array('Manuel', 'StackOverflow');

and I have this query..

mysql_query("INSERT INTO users(name, fav_site) VALUES(?, ?)");

So, I’d like to replace the question marks with those values in order, so Manuel goes first and then goes StackOverflow. Remembering that I need to add -> ‘ <- at the sides of these values so MySQL doesn’t throw an error.

I have tried searching if someone has asked this and had no luck.

Any help is appreciated!

NOTE: I know I shouldn’t even bother with MySQL, but hey! A feature is a feature.

<?php
$query = "INSERT INTO users(name, fav_site) VALUES(?, ?)";
$args = array('joe', 'google goggles');
while(strpos($query, '?') !== FALSE)
{
  $query = preg_replace('/\?/', your_quoting_func(array_shift($args)), $query, 1);
}
echo $query;

Basically, this says…while there is still a ? remaining in the string, delete the first question mark and replace it with a quoted (use your own function or mysql_real_escape_string and surround with single quotes) string, and shift that item off the array. You should probably substr_count the ? marks versus the number of arguments for error checking.

I used preg_replace because it accepts an argument specifying how many values to replace, whereas str_replace does not.
