A little help with processing a string

[sierradog70]

Hey,

 

I have a form I am making for my site.  Lets say the form is on page1.php.  The user enters a domain on that form (ex domain-777.com)

It sends all this to page2.php

Now on page2.php I want the script to find out how many hiphens and numbers the entry has.  I want it to know they entered 1 hiphen and 3 numbers.

I believe I do this with the strstr function, but I am not sure.  Even if I do, I don't know exactly how to do it.

 

Please help

 

Thanks!

There's a function specifically for that:

 

http://sg.php.net/manual/en/function.count-chars.php

On that page, it has ($data, 1) <-- what does the 1 do?  Also, what does the variable $i go to?

[btherl]

The 1 selects the mode the function runs in.  There's a list on that page near the top.

 

The $i variable is the key.. the array returned looks like this:

 

array(

  'c' => 5,

  '.' => 1,

  '-' => 3,

);

 

That foreach loop sets $i to be the "key" or "index", which is the character, and $val to be the "value", which is the number of times character $i appears in the string.

 

Try the example script with a few input strings to get an idea of what's going on.
