Re: checkbox

Here's a possible solution.
Step 1, Create an empty array.
Step 2, Evaluate each checkbox in a loop. If empty, push a 0 into the array. Else, push a 1 into the array.
Step 3, Implode the array using a comma as the "string glue":

php Syntax (Toggle Plain Text)
<?php
if(isset($_REQUEST["submit"])){
$checkarray = array();
$numCheckBoxes = 5; //number of checkboxes to evaluate
	for($i=1; $i<=$numCheckBoxes;$i++){	
		if(empty($_REQUEST["check".$i])){
		array_push($checkarray,0);
		}else{
		array_push($checkarray,1);	
		}
	}
$checkstring = implode(",",$checkarray);//create comma separated string from array
echo $checkstring;//outputs:1,0,1,1,0 
}
?>
<?php
if(isset($_REQUEST["submit"])){
$checkarray = array();
$numCheckBoxes = 5; //number of checkboxes to evaluate
	for($i=1; $i<=$numCheckBoxes;$i++){	
		if(empty($_REQUEST["check".$i])){
		array_push($checkarray,0);
		}else{
		array_push($checkarray,1);	
		}
	}
$checkstring = implode(",",$checkarray);//create comma separated string from array
echo $checkstring;//outputs:1,0,1,1,0 
}
?>

This code assumes that the checkboxes are named check1,check2,check3,check4,check5...

Re: checkbox

(Toggle Plain Text)

echo RemoveComma($checkstring);

or just use.

$str = str_replace(',', '', $a); 

function RemoveComma($a) {
		 $str = str_replace(',', '', $a); 
		 return $str;
		 }

Re: checkbox

The way I would do for performance and speed is as follows:

php Syntax (Toggle Plain Text)
$tmp =$_REQUEST["check1"];
$tmp .=',' . $_REQUEST["check2"];
$tmp .=',' . $_REQUEST["check3"];
$tmp = str_replace(',,',',',$tmp);
 
//now to turn into an array
$darray = explode(',',$tmp);
 
//now to display the array
echo '<xmp>';
print_r($darray);
echo '</xmp>';
$tmp =$_REQUEST["check1"];
$tmp .=',' . $_REQUEST["check2"];
$tmp .=',' . $_REQUEST["check3"];
$tmp = str_replace(',,',',',$tmp);

//now to turn into an array
$darray = explode(',',$tmp);

//now to display the array
echo '<xmp>';
print_r($darray);
echo '</xmp>';
