In some cases you can use this. <FORM ACTION="receiver.php" METHOD=POST> <INPUT TYPE=CHECKBOX NAME="arreglo[]" value="1">Thing #1 <INPUT TYPE=CHECKBOX NAME="arreglo[]" value="2">Thing #2 <INPUT TYPE=CHECKBOX NAME="arreglo[]" value="3">Thing #1 <INPUT TYPE=CHECKBOX NAME="arreglo[]" value="4">Thing #4 <INPUT TYPE=SUBMIT> </FORM> In the case you mark two (1 & 3) you will have that result: sizeof($_POST[arreglo]) -> 2 the different is that you can use: for($i=0; $i<sizeof($_POST[arreglo]); $i++) Because the array is like that: $_POST[arreglo]=array( '0'=> '1', '1' => '3'); Another thing. If you have an array with null values, use this: count(array_keys($array)); ---- Server IP: 130.206.1.5 Probable Submitter: 84.77.100.3 ---- Manual Page -- http://www.php.net/manual/en/function.sizeof.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+61809 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+61809&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+61809&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+61809&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+61809&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+61809&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+61809&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+61809&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+61809&report=yes Search -- http://master.php.net/manage/user-notes.php
