I discovered a rather bad bug in my __json_encode function below. On versions prior to php 5.2.5,
all 'f' characters are escaped to '\f'. This is because addcslashes in php <
5.2 doesn't understand \f as "formfeed". The fix is simple:
<?php
# Change this line:
$string = '"' . addcslashes($data, "\"\\\n\r\t\f/" . chr(8)) .
'"';
# Into this:
# I also put the \\ character first, as suggested in comments on the 'addclashes'
page.
$string = '"' . addcslashes($data, "\\\"\n\r\t/" . chr(8) .
chr(12)) . '"';
?>
