which page loads faster? .php .htm or .shtml

[jaymoore_299]

Earlier I had a shtml file and included some php code in it, and within that code there was a setcookie command. Whenever I ran this code everything in the included php code ran fine except for the setcookie. I had to change my .shtml page into a php page and have the section with the setcookie code written out in that page to get it working.

However, I was wondering now that I changed my page to .php , will it load slower than if it was a shtml or an html ?

Well the php needs to be parsed but you wouldn't normally notice any difference. Were talking miliseconds.

servers are configured to parse specicifc file types for specific directives. if your server is setup to parse .php files for PHP code and you have file that you know contains no PHP then you should name it with another extension (.html) as the server will not have to waste time parsing it for PHP. simliarly, if your server is setup to parse .shtml files for SSI directives and you have file that you know contains no SSI then you should do the same. if you wish to mix PHP and SSI within the same file you must name it with an extension that your server has been configured to parse for both.

i will add (as thorpe suggested) that the differences are probably neglible (in a real world situation).
