Pass an multi variables array from php file to javascript external file

[Nati Aizikovitz]

php code:

$array = array($variable-1, $variable-2, $variable-3, ….. variable-n);

echo jason_encode($array);

 

javascript code:

var ar = new XMLHttpRequest();

ar.onreadystatechange = function(){

if(this.readyState == 4 && this.status == 200){
 var obj = JSON.parse(this.responseText);
             document.forms["form1"]["fnameMsg"].value = obj[0];
             document.forms["form1"]["lnameMsg"].value = obj[1];
             document.forms["form1"]["mphoneMsg"].value = obj[2];

}

}

The above code create an error:

Uncaught SyntaxError: Unexpected token < in JSON at position 0

Can someone help me to understand what is wrong with the above code and how to correct it.

Thanks.

Your PHP code is calling an undefined function, so it's showing an error message which is not valid JSON.
