Help with strings

[amrclutch1]

I need to count the number of characters from a word in a string with spaces.

 

EX:

 

Let the string be "user_cp".

 

perform a str_replace("_", " ", ucwords(trim(strtolower($string))))

 

Therefore I have "User cp".

 

Now I want to perform something that counts the number of words in it, excluding spaces, then checks if it has only 2 characters, if so, perform a

 

strtoupper($selectedword);

 

Then extracting it back to the string as "User CP".

 

I am looking forward to any help!

try using strpos to search

[darkfreaks]

<?php
$user = 'Selected cp';
$pos = strpos($user, 'c','p'); /// will return first occurence of 'cp'

$replace =  strupper($pos); /// replaces first occurence of cp with CP

?>

There is a PHP built in function "str_word_count"

[darkfreaks]

my code does the same thing but for the first occurence of it only

I can't use strpos, I need it to search for any words with 2 chars, not necessarily cp only, any other ideas?

[darkfreaks]

you should use eregi replace only other thing i can think of

Im certainly sure there's a simpler and faster method but this is what i came with:

 

<?php
$sentence = 'This is some text on a variable';
$words = explode(' ', $sentence);
for($i=0; $i<count($words); $i++){
if(strlen($words[$i]) == 2){
	$words[$i] = strtoupper($words[$i]);
}
}
$sentence = implode(' ', $words);
echo $sentence;
?>
