Felix Ker's blog

Lately I touched more PHP than felixker.com. (Notice that I blog less!)

I’ll keep this entry short and simple since it’s 12am and I should be in bed by now.

Some in-built functions I found very useful.

urlencode

This is a must-use function if you’re going to use query strings ($_GET) to pass variable to another page! Remember to use urldecode when using the variable!

Example:
$string = “i have a cute & tiny dog!”
header(”Location: http://felixker.com/foo?bar=));

htmlentities

Wonderful function to use if you’ve got a page with form submission. Prevents users from playing tricks!

Example:
$str = “A ‘quote’ is <b>bold</b>”;

// Outputs: A ‘quote’ is &lt;b&gt;bold&lt;/b&gt;
echo htmlentities($str);

Conclusion

I must end this entry. I need to sleep.

There are many more functions I used, but I just cannot remember them. Most of them are functions that I cannot find built into VB.net. (Correct me if I’m wrong.)

Good night.
