how to solve json encoding problems with php.

Hello again..if you ever work with json in php..maybe you ran into some problems with json_encode() function like me wink.

so in this tutorial i like to share two problems i ran into.and how to solve them

1-First problem when json_encode return not valid code on chrome and work good with firefox or other browsers
The answer : go to notebad++ , choose the "Encoding" menu, then "Encode in UTF-8 without BOM" or with phpstorm go to “file”,then  remove bom

2- the second problem with jeson_encode function to return not valid code when try to convert array which has contained special characters or html tags .
The answer :  use the second parameter to add constants to define and convert these tags

$a = array('<foo>',"'bar'",'"baz"','&blong&', "\xc3\xa9");

echo "Normal: ",  json_encode($a), "\n";
echo "Tags: ",    json_encode($a, JSON_HEX_TAG), "\n";
echo "Apos: ",    json_encode($a, JSON_HEX_APOS), "\n";
echo "Quot: ",    json_encode($a, JSON_HEX_QUOT), "\n";
echo "Amp: ",     json_encode($a, JSON_HEX_AMP), "\n";
echo "Unicode: ", json_encode($a, JSON_UNESCAPED_UNICODE), "\n";
echo "All: ",     json_encode($a, JSON_HEX_TAG | JSON_HEX_APOS

Also if you want to trace json errors and you dont know where it comes from you can use json_last_error with json_last_error_msg to show and trace the error
