PHP Caching Method - Webmaster Forums - Webmaster forum for HTML, PHP, ASP, CSS and more

Hi guys,

I need to seek some advice from you in regards to the following questions:-

1) I found out there are many ways to cache a website content to make the website load faster. But I'm not sure which method is better than the others like for example HTTP Cookie and Server Caching. If a website like mine that uses MYSQL database and retrieve a lot of data to display on user's end, what caching solution is the best?

2) There are many PHP scripts available from the open source community and retail market. Some spec out the requirements and specifications in very details but unfortunately some don't. How can I be sure the script can support a big traffic site? Often I heard many scripts are written for website with small traffic in mind and they will start to behave strangely if the traffic started to grow.

Please do share your ideas and comments. Thank you.

Cheers,

The HTTP header is sent before you send any HTML to the client.

Thus, if you have a single space in your code... anything at all before you call a function that makes use of the HTTP header (i.e. the "session" call).... it will fail, as the header has already been sent.

For this, you need to make sure your document starts with <?php , without any data before it... then immediately call the "session" function, or whatever resource you are using that makes use of the HTTP header.
