FIND Specific char and counting it..

[harris97]

Well i'd like to count how many dots are there in a sentence. example
$text="my name is joko. my mom is siti. and my father is jack."
Dots (.) in that sentence ($text) are 3. But how to count that in PHP?

thanks for anybody helping me

function countInstances($string, $char)
{
$instances = 0;
for ($i=0; $i<strlen($string); $i++)
{
if ($string[$i] == $char)
{
$instances++;
}
}

return $instances;
}

$text="my name is joko. my mom is siti. and my father is jack."

echo countInstances($text, '.');
