Question

I have some Data like this in PHP:

NumberOfPeople.php
<?php
$numberOfPeople = 5;
?>

How do I convert that variable into a JSON Object and then output it into an HTML file.

Something like this:

RandomHTMLFile.html
<script type="text/javascript">
  var NumberOfPeople = JSON VARIABLE FROM THE PHP FILE
</script>

This is the type of thing JSON is for right?

Notice that the Output file is in an HTML file and not a PHP File, so it has to be completely Javascript based.

Also the HTML file will be on a different server than the PHP file.

Answer 1

Change it into a PHP array and use json_encode() function

$jsonArray = array('numberOfPeople' => 5); //Now the value will be accessible under `numberOfPeople` json index
$json = json_encode($jsonArray);
echo $json;
