如何获得多个复选框的REAL值？

Question

I have a multiple checkbox in my html table with $number as index ">

I get the value of the multiple checkbox:

$checklist = $_POST['checkbox'];

The value of the $checklist are correct when i do echo.

$i = $checklist[0];
echo $i; // 2 for example

Now i try to get the node number $i (2) in my xml file

$participants = simplexml_load_file($fileName); Then this line echo $participants->participant[$i]->name; display blank

Or if define $j = 2; then echo $participants->participant[$j]->name; display the name of the participant 3 ($j + 1) and that is correct.

That mean $check or $i = $checklist[0]; don't give a simple number like $j, any idea please ? Thanks in advance.

Answer 1

The problem is just because php type the variable, so $check is not int type, $j is int type. Just do $i= (int)$check and it works well when doing $participants->participant[$i]->name; Thansk for your participation.
