PHP Newbie: Proper handling of Error & Exception in PHP
Got a question from a friend today who is actually a great desktop programmer and just learn PHP since he believe that the future is in the web (hope you’re right dude). He asked me about how to handling error in PHP. Well i’ll write my answer here so can share with others and got feedback when I was wrong.
In PHP there are few options that you can use to handle errors & exceptions during script executions and as developer you must considering not the easiet but the most flexible approach which will help you when debugging your appllication, the more detail error message provided the faster you can fix it. Flexible means its easy for you to change the application behaviour when unexpected things happened during execution like: display error, logging error or even automatically notice you via email.

Use custom fonts, PHP, DOM & Javascript Image Replacements
Using custom fonts sometimes can give a different “soul” to the web page, but as a good web designer we shouldnt fully strict to the “looks & feels” but also the accessibility, cross compatibility, always try to make it present almost in the same way across different screen readers, browsers, and media. now days we also need to consider of SEO, and use image directly to the page to replace the important phrases is not a best practice.

Is there a secret behind file encoding in PHP?
Today i faced a strange warning message when executing a PHP file,
Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at file.php:1) in file.php on line 15
Well not the error message, but the reason that produce this message, i have tried to use different solutions to avoid this error:
- Put the session_start() command in the very first line
- Explicit set of session_save_path
- Change the permission (CHMOD 777)
- Reset the php.ini session auto start + Explicit set on the codes
but none of ‘em fix the error. Then i try to use unusual test, changing the file encoding from UTF-8 (i always save my file in UTF-8 encoding) to ANSI, and Booom! the error message gone 
.
Didnt really know how the file encoding can cause this error, because i always use UTF-8 and produce the same code and never get this error. Is there any secret of file encoding on PHP?, now you tell me , because within ANSI i could not produce foregin characters, so i need a better solutions, to kiss this error away and keep the UTF-8 encoding.
Any suggestions guys?
