Php directly outputs json format

Php directly outputs the json format. many new users have a misunderstanding that echo json_encode ($ data) is used to output json data. If yes, the output text is in json format rather than json data, the correct statement should be followed by one sentence:

 
Example: JSON data formatting function. format JSON data in the string form into the indent form. the JSON string converted by json_encode is not indented. this method is much better. here, tab indentation is used by default. to change it to a space, replace the variable $ indentStr. the code is as follows:
/**  * Indents a flat JSON string to make it more human-readable. * @param string $json The original JSON string to process. * @return string Indented version of the original JSON string. */function indent($json) {    $result = '';    $pos = 0;    $strLen = strlen($json);    $indentStr = '';    $newLine = "\n";    $prevChar = '';    $outOfQuotes = true;    for ($i = 0; $i <= $strLen; $i++) {        // Grab the next character in the string.        $char = substr($json, $i, 1);        // Are we inside a quoted string?        if ($char == '"' && $prevChar != '\\') {            $outOfQuotes = !$outOfQuotes;            // If this character is the end of an element,            // output a new line and indent the next line.                    } else if (($char == '}' || $char == ']') && $outOfQuotes) {            $result.= $newLine;            $pos--;            for ($j = 0; $j < $pos; $j++) {                $result.= $indentStr;            }        }        // Add the character to the result string.        $result.= $char;        // If the last character was the beginning of an element,        // output a new line and indent the next line.        if (($char == ',' || $char == '{' || $char == '[') && $outOfQuotes) {            $result.= $newLine;            if ($char == '{' || $char == '[') {                $pos++;            }            for ($j = 0; $j < $pos; $j++) {                $result.= $indentStr;            }        }        $prevChar = $char;    }    return $result;}
Well, the json database output in this way is very beautiful and formatted. I will not give an example here. please refer to it without your defense.
