Strings

[Phoenix_Down]

I need some help with with strings:

1. How do I make a string insert a space after a certain number of characters?

2. How do I check if a string has at least one letter or number?

Can you be more specific with what you want to do on #1. Will you be doing the replace only once, or something like every 5 characters add in a character?

For your second question, you would use the function strlen()

The 2 functions you're going to need are:

1. http://www.php.net/substr
2. http://www.php.net/ereg

If you need any help implementing them, post again, we'll see what we can do 😉

Every xx characters add in a character is what I want to do.

For #2 would this work to check if $variable has at least one letter or number?

if(eregi('^[_a-zA-Z][0-9]$',$variable)  { 
// code here
}

Thanks for the replies! 🙂

Okay, I got the eregi thing to work:

if (eregi("[a-zA-Z0-9]", $field2)) {
       echo "blah";
}

Can someone help me with my first question?
