trouble with for PHP for loop return value

[jepler]

I haven't created loops in PHP so I need some help. I'm trying to return a total arithematic value as items are looping.

[code]foreach($items as $item) {

if (strstr($row_Recordset1['schedule_id'], $item['id'])){ //if an item in the loop meets this condition
$number+10 ; //add +10 to the number
}
$number + 1;
}

echo $number; //this should be the total value returned from the loop
[/code]

I know the code above is terrible but hopefully it can reveal what I'm trying to do.thx.

You have to assign the value to the variable like so:

[code]
foreach($items as $item) {

if (strstr($row_Recordset1['schedule_id'], $item['id'])){ //if an item in the loop meets this condition
$number = $number+10 ; //add +10 to the number
}
$number = $number + 1;
}

echo $number; //this should be the total value returned from the loop
[/code]

[code]
<?php
foreach($items as $item) {
 if (strstr($row_Recordset1['schedule_id'], $item['id'])) {
   $number += 10;
 } else {
   $number += 1;
 }
}
echo $number;
?>
[/code]

thanks for your reply. Okay, got it. But I guess that's not going to help me do what I want to do. Instead of performing a running tally, I guess I need instead to return the total for each instance of the loop and then set the number back to 0, or something.

I want to do something like this:

[code]<input name="<?php echo $row_Recordset1['schedule_id']; ?>
" type="checkbox" id="<?php echo $row_Recordset1['schedule_id']; ?>"
value="<?php echo $row_Recordset1['class_name']; ?>"

<?

if the schedule_id number IS found somewhere in the array item,
echo "checked onClick=goSomeWhere";

if the schedule_id number is NOT found in the array item,
echo "onClick=goSomeWhereElse";

?>

after reviewing what i just posted, i see i left out the original code I had a question about!! Sorry about that! Maybe I'm approaching it the wrong way? I want an input checkbox field to be checked and an OnClick event to be available if the item is in the array; if it's not, I want a different onClick event to be available in the input checkbox field. Seems like I can get the first condition to work but the second onClick event shows up in every input box regardless.

<? <?php do { ?>
<input name="<?php echo $row_Recordset1['schedule_id']; ?>
" type="checkbox" id="<?php echo $row_Recordset1['schedule_id']; ?>"
value="<?php echo $row_Recordset1['class_name']; ?>"

<?php
foreach($items as $item) {
  if (strstr($row_Recordset1['schedule_id'], $item['id'])) { 
    $number += 10;
    echo "checked onClick=goSomeWhere"; //if the schedule_id number IS found somewhere in the array item check the box and print this onClick function;
  } else {
    $number += 1;
  }
}

if ($number > 10) {
    echo "onClick=goSomeWhereElse";  //if the condition is not met above print this other function;

?>
