[SOLVED] array or string search

[asmith]

how can i search a string or an array to find out how many a word or a value has been repeated ?

 

for example : 

 

$a = array ("a","b","c","a","a","c","d");

$b = "a,b,b,b,c,c,a,a,a,d";

 

how can i find how many "a" are in those ?

(actuallly with implode and explode , it will be one question)

preg_match_all will do this quite easily.

$a = array('a','b','c','a','a','c','d');
$b = array_count_values($a);
echo $b['a']; // number of a's
print_r($b);
