Following several other posts with the "common mistakes PHP developers make" theme, Bruno Skvorc has posted his own list of seven things he sees developers doing over and over.
Back at the end of June, TopTal, the freelance marketplace, published a post about 10 Most Common Mistakes PHP Programmers Make. The list wasn't exhaustive, but it was well written and pointed out some very interesting pitfalls one should be wary of - even if I wouldn't personally list the mistakes as very common. I encourage you to give it a thorough read - it has some truly valuable information you should be aware of - especially the first eight points.
His additions to the list of common mistakes includes:
- Using the mysql extension
- Not rewriting URLs
- Assigning in Conditions
- Being Too Transparent
You can read the full list and summaries of each in the rest of the post.
