display string variable in web browser ( n characters per line)
Is it possible in php to display in web browser string variable with specified number of characters per line.
For example variable
s="44444444"
Is it possible to displays s in web browser with 2 characters per line?
Like this:
44
44
44
44
If you know how to do this, could you give exact code.

 

Use http://uk2.php.net/substr to break the string into 2 character sections and then echo each section on a new line.

Or use a function to insert /n or <BR> every 3rd character.

 

http://se.php.net/manual/en/function.wordwrap.php

Use this function to wrap a string into lines with a specified number of characters then use the nl2br function to insert <br>'s.
