!!@%%#! count() problem

[zzyzxx]

Can anyone help me figure out what's wrong with this?
count() returns 1, but print_r shows there are 3 elements in the array! how can i properly count the array elements?
tia.

$string = "fa199.33.222.11sdbsdf56.333.22.666sdfa44.22.333.44";

preg_match_all("/[0-9]{1,3}[.][0-9]{1,3}[.][0-9]{1,3}[.][0-9]{1,3}/", $string, $matches);
$num=count($matches);
echo 'number of matches= '.$num;
echo '<br />';

print_r($matches);

it's because $matches has 1 element in it; this element is itsself an array of 3 elements. Not sure why this is happening, not too good with pregs, but change the following line and you'll see what i mean

$num=count($matches[0]);

zend debugger gives the following output with this line changed as above

number of matches= 3
<br />
Array
(
[0] => Array
(
[0] => 199.33.222.11
[1] => 56.333.22.666
[2] => 44.22.333.44
)

)

see?

yes, thanks very much, weekender.

i'm having some sort of conceptual difficulty with these arrays in php...😕 i'll have to do a bit more reading to figure these little buggers out.

thanks again.
