counting an array

[iulian.ilea]

Hi,

How can I count how many variables are in an array. I give an example
to make my self clear enough:
$arr[0]="fds";
$arr[1]="fdfs";
$arr[2]=null;
$arr[3]="213";

count($arr) will return 3. I searched on php.net and I couldn't find a
function that return 4 (in this example).

$arr = array();
$arr[0]="fds";
$arr[1]="fdfs";
$arr[2]=null;
$arr[3]="213";
echo count($arr); // Returns 4 on my system

Re: counting an array

Returns 4 on my system too.
I have this code:
function font($_text, $_face=null, $_color=null, $_size=null,
$_class=null)
{
/*************** **
text, face, color, size
$_SESSION["vars"][3]
$_SESSION["vars"][1]
$_SESSION["vars"][4]
*************** **/
$var=Array();
$var[0][0] = $_text;
$var[0][1] = $_text;
$var[1][0] = $_face;
$var[1][1] = "face";
$var[2][0] = $_color;
$var[2][1] = "color";
$var[3][0] = $_size;
$var[3][1] = "size";
$var[4][0] = $_class;
$var[4][1] = "class";
$result = "<font ";

for ($i=1; $i<count($var); $i++)
if (!empty($var[$i][0])) $result = $result . $var[$i][1] . "=\"" .
$var[$i][0] . "\" ";

$result = $result . ">" . $_text . "</font>";
return $result;
}
}

try return $count(var).
