php json_encode bug patch

Question

i have data in text file which i load to array rows wise , but recently i have noticed that when "µ" come in data then json_encode retrun blank response ,and when i remove "µ" from data then json_encode function work

i have php version 5.5.3

$dat = array("0"=>"hello","1"=>"world");
echo json_encode($dat);   // work

$data = array("0"=>"hello","1"=>"180.00 10µH");
echo json_encode($data);  // blank response ..

i searched for json_enocde function on github php page , but its all in C ,

so any idea how to patch this function

Just tossing this out there, from the json_encode() documentation page: "All string data must be UTF-8 encoded." That being said, the JSON_UNESCAPED_UNICODE bitmask option sounds promising. — Spencer D

Use the following code:

function utf8_converter($array) {
    array_walk_recursive($array, function(&$item, $key) {
        if (!mb_detect_encoding($item, 'utf-8', true)) {
            $item = utf8_encode($item);
        }
    });

    return $array;
}

$data = array("0"=>"hello","1"=>"180.00 10µH");
$data = utf8_converter($data);
echo json_encode($data, JSON_PARTIAL_OUTPUT_ON_ERROR);

Your code output: ["hello","180.00 10\u00b5H"]. Notice the µ converted to respective special characters(\u00b5).

@BhavikShah yes, right. It will do it. But whenever you are converting it back using json_decode it will come back to it's origin form. So don't worry about it.

Try this:

$dat = array("0"=>"hello","1"=>"world");
echo json_encode($dat);   // work

$data = array("0"=>"hello","1"=>"180.00 10µH");
echo json_encode($data, JSON_UNESCAPED_UNICODE);
