Question

I have the following code which encodes json in php

$arr = array('htmlOutput' => $htmloput, 'no_rows' => 'blah');
    echo json_encode($arr);

$htmloput contains html mark up.

For some reason, there is a lot of \r\n\t\t\t\t\t\t\t in the output. Also, do single quotes or double quotes in the markup cause any proples when you encode in JSON?

Answer 1

Those characters are text-representations of whitespace characters. \r is carriage-return. \n is newline. And \t is tab. Quotes shouldn’t matter.

Some others (from the string docs):

• “\t” (ASCII 9 (0x09)), a tab.
• “\n” (ASCII 10 (0x0A)), a new line (line feed).
• “\r” (ASCII 13 (0x0D)), a carriage return.
• “\0” (ASCII 0 (0x00)), the NUL-byte.
• “\x0B” (ASCII 11 (0x0B)), a vertical tab.
