search string using case sensitive

[epots9]

sorry in advance, i'm just tried..

ok, i need to search a string for something and i want it to return the location of where in the string it is (like the function strpos()), but i need to know the location of where a lowercase letter is immediately followed (no space, no thing between) by a uppercase letter.

I have a feeling it has to done using regular expressions (not sure), and i'm not the greatest at those right now....

open to all suggestions,

Thank You.

Ideal here
use

strtolower() function to convert everything in lower case
then use ucfist() to convert the first letter in a string as an upper case.

You will know that the second letter is in lower case.

Regular expressions unfortunately won't help a whole lot because there's no preg_pos function. But you can do this:

[code=php]
$array = preg_split('/[a-z][A-Z]/', $string, 1);
if(empty($array[1]))
// Not found
else
$offset = strlen($array[0]);
[/code]

If your $string were '012345nG89' (expected return value will be 6), then preg_split would divide the string into:

[code=php]
array(
0 => '012345'
1 => '89'
)
[/code]

If you strlen() the 0th element of that array, you get 6.

[EDIT: Not sure if $array[1] will be set if the target pattern is at the end of the string (e.g., '012345nG').]
