<?php

        //get the input value

        //all vowels in an array
        $vowels = array('a','e','i','o','u','A','E','I','O','U');
        
		//find length of the string
        $len = strlen($string);
        
		$num = 0;
        $only_vowels = '';
		
        //loop through each letter
        for($i=0; $i<$len; $i++){
            //if vowel letter found concat in $only_vowels;
			if(in_array($string[$i], $vowels))
            {
                $only_vowels .= $string[$i];
            }
        }
		
		//if vowels found
		if(strlen($only_vowels) > 0){
			//print all the vowels
			print "<b>Stripped vowels:</b><br>";
			print $only_vowels."<br><br>";
			
			//also print the counts of each vowel
			print "<b>Each vowel count: <br></b>";
			foreach(count_chars($only_vowels, 1) as $k=>$v){
				echo chr($k).' '. $v .' time(s) <br>';
			}
		}else{
			echo "No vowels found.";
		}
	}
 
?>

Just read the in-line comments to understand the script.

Example output of the above script: 

Input String: 
This is just an example

Stripped vowels:
iiuaeae

Each vowel count: 
a 2 time(s) 
e 2 time(s) 
i 2 time(s) 
u 1 time(s)
