The International PHP Magazine has posted the results from their latest poll where they asked their readers "which is the most common PHP database problem?"

The options were:

• Using MySQL directly
• Not using auto-increment functionality
• Using multiple databases
• Not using relations
• The n+1 pattern

And coming out on top (with 27.5%) was "Not using relations" in the SQL statements made. Following close behind was "Using MySQL directly" and falling in last was "Not using auto-increment functionality".

Be sure to vote in this week's poll that asks "Which is Truest?" - given several popular opinions on PHP, pick the one that you think is the most true.
