Hello, I am making a grade calculation application, I was wondering if anyone could help me with some error handling examples, the code will be listed below.
--------------function page
function getTotal($input_text){
$lines = explode("newline", $input_text);
$total_marks = 0;
foreach ($lines as $line) {
$line_array = explode(",", $line);
$total_marks += $line_array[1];
}
return $total_marks;
}---------------------index.php page
<?php
header("Access-Control-Allow-Origin: *");
header("Content-type: application/json");
require('functions.inc.php');
$output = array(
"error" => false,
"string" => "",
"answer" => 0
);
$input_text = $_REQUEST['input_text'];
$answer=getTotal($input_text);
$output['string']=$input_text."=".$answer;
$output['answer']=$answer;
echo json_encode($output);
exit();
