PHP function to convert only words in UPPERCASE to Startcase

I needed a function in PHP that would convert words in uppercase to Startcase, i.e. the first letter of the word in uppercase and the rest in lowercase. A combination of ucwords with strtolower can do that, however, I only wanted the words that were fully in uppercase to be converted, not the other words.

To give a example, I wanted
SHINKANSEN SAKURA 555 naar Hiroshima (treinpas valideren in Shinagawa station)
to be converted to
Shinkansen Sakura 555 naar Hiroshima (treinpas valideren in Shinagawa station)
(and not to)
Shinkansen Sakura 555 Naar Hiroshima (treinpas Valideren In Shinagawa Station)

You can do that relatively easily with preg_replace_callback:

This replaces any word of least 2 capital letters to a word with only the first letter capitalized.

Dealing with UTF-8 text using the PHP mail()-function

On one of my PHP-based websites, users can send mails via a simple text form. I had a problem with special characters in the subject or message body. The webpage has a <meta charset=”utf-8″ />-tag, which causes problems when people enter special characters, like é or € or “smart quotes”. They get sent via the mail()-function and show up like Ã³ or Ã© or â€™.

Deep down in the user comments in the documentation on the mail()-function, I found a small function that solved this easily:

Just use mail_utf8() instead of mail() on a UTF-8 page and a proper UTF-8 mail will be sent out.

Windows 7 + IIS 7.5 + php 5.3.1 + MySQL 5.1: no good combination

I recently installed Windows 7 on my laptop. I also configured IIS 7.5 on it, installed php 5.3.1 and MySQL 5.1.

Everything seemed to be installed correctly: I could see the IIS 7 Welcome screen, I could look at the php configuration with phpinfo() and I could see the MySQL tables using the MySQL Administrator GUI.

But when I tried to use phpMyAdmin, I got stuck: after trying to load the homepage of phpMyAdmin for 20-30 seconds, I got an HTTP Error 500. I searched the internet for hours, trying to find somebody with a similar experience, but I did not find any valuable resources.

Even a very simple test-script like

generated a HTTP 500-error, after a 20-30 seconds wait.

Eventually, I decided to look at what I had installed when I was still using Vista. The difference seemed to be php: on my previous system, php 5.2.10 was installed.

I finally uninstalled MySQL and php 5.3.1, and then reinstalled php 5.2.11 and MySQL 5.1.41. That combination seemed to work without issues.

Conclusion: IIS 7.5 + php 5.3.1 + MySQL 5.1 does not seem to be a workable solution (for now). Stick to the 5.2-branch of php if you want to use it on Windows 7/IIS 7.5.
