To change MySQL databases within code use the mysql_select_db() function like this:

<?php
 mysql_select_db(‘db_2′, $mysql_link);
$query = “SELECT username from user where userid = ‘$user_id’”;
$result = mysql_query($query,$mysql_link);
        if(mysql_num_rows($result)) {
                $row = mysql_fetch_row($result);
                $username = $row[0];

Finding out the number of days elapsed from a UNIX timestamp is actually pretty straightforward. If you only know two dates then first you’ll need to convert the date to a UNIX timestamps and then subtract the most recent timestamp from the older timestamp like this:

<?php
$old_timestamp = 1102971600;

$string = “?This is a test that should be in single quotes quotes?”;
$text = preg_replace(”/(\?([^\?]+)\?)/”,”‘\\2′”,$string);

I wanted this program to remember what year of our anniversary it was without me having to remind it: a great use for […]

So you are getting a weird parser error at a line of code that doesn’t have any errors? Here are some tips and tricks I’ve compiled over the 6+ years I’ve been doing PHP scripting for tracing various PHP errors in source code:
1. Start commenting out code near the parser error line number. Start by […]
