preg_replace? string formatting help

[triphis]

Hello I have tried to understand this function, but I just do NOT get it.

 

I have tried to look at the copious "format phone numbers" scripts available, but I can't seem to change it to work for what I need.

 

I actually need two forms:

 

First, I have a number like this: 3032 stored in a DB, and I need to format it 30 x 32 (pant sizes lol).

Also, a bit more complicated, I have either 325, or 32500 stored in a DB, and I need it to come out $325.00

 

This is for a little store website I am writing. Nothing in this store in less than $10 or more than $999, so basically, the first 2 or 3 digits will be the dollars.  If the number is 4 digits long (4595) I need it to know to do $45.95    Three digits long would need .00 ADDED (because nothing would be $X.XX)  5 digits would obviously be XXX.XX  and two digits would have .00 ADDED

 

 

Thank you, and if you can even link me to a good resource for this, that would be GREAT!

$num = 3032;
$len = substr($num, 0, 2);
$wid = substr($num, 2,2);

print $len . " " . $wid;

 

$price = 4595;

$price = number_format($price, 2, ".");

print $price

For your first question... take a look at substr.

 

As for your second... take a look at number_format.

I was actually going to ask why you chose to store your data this way instead of as a decimal field for the money, and a varchar field for the "size"?

Thank you frost and thorp

 

i will have to edit the price one a bit so that it adds the .00 where necessary, but that works just fine, thanks I didn't expect it to be so simple. obviously I am new to this

 

dough boy, I was not aware that there is a decimal field o.O  not "int" is it?

 

and I do actually have the size in a varchar field.  I guess I don't really know why I am making it more difficult on myself... I am clearly going to have to rethink my DB structure LOL
