can u count how many a's in a string...

[brown2005]

if i have

$reply = "Yes I am able to go to the pub tommorrow";

can i count how many a's are in it....

so $reply_count_a = "2";

Look at the substr_count function in the manual!!

[code]<?php
$letter = "a";
$reply = "Yes I am able to go to the pub tommorrow";
$number = substr_count($reply, $letter);
echo $number; // echos 2
?>[/code]

Another way that comes to mind is preg_match_all(), but it may be overkill for what you're after:
[code]
<?php
$String = "Yes I am able to go to the pub tommorrow";
preg_match_all('|a|i', $String, $matches, PREG_SET_ORDER);
echo count($matches) . " a's found!";
?>
[/code]

Try it and see... I haven't actually tested it yet :(

here´s another way

[CODE]<?php

$reply = "Yes I am able to go to the pub tommorrow";
echo strlen(preg_replace('/[^a]/is', '', $reply));

?>[/CODE]
