PHP4 : count_chars() function (or something like that).
PHP3:
<?php
$text = "How many p's are there in apple?";
$len = strlen($text);
for ($index = 0; $index < $len; $index++){
$char = $text[$index];
if (!isset($counts[$char])){
$counts[$char] = 0;
}
$counts[$char]++;
}
while (list($char, $count) = each($counts)){
echo "$char: $count<BR>\n";
}
?>
