php declare statement

[dennismonsewicz]

can someone explain what the declare statement is used for?

 

I read about it in the PHP manual but I am not fully grasping the concept.

It's used to make a date a constant meaning it never changes which is available throughout the script without a need to use the global.

 

It's mainly used on config files for you database connection data for example.

hmmm ok... is it really a helpful function?

[nuttycoder]

it can be, I din't use it at all until recently I use it a lot to store things like file paths.

 

Instead if having to pass variables to a functions it's already available. I recommend giving it a try.

but how does this function differe from using the define function?

Youre right.. declare() and define() are different

 

I've never used declare() before but the tick option looks useful for debugging or monitoring something. Not really sure how to use the encoding part either..

 

Maybe someone else can shed some light on this.

 

But this is something you probably woudnt use much, if ever..

oh sorry I misread your first post I thought you said define when you said declare, I've never used declare.
