getting json_encode to not escape html entities
Solution 1
Neither PHP 5.3 nor PHP 5.2 touch the HTML entities.
You can test this with the following code:
<?php
header("Content-type: text/plain"); //makes sure entities are not interpreted
$s = 'A string with & ۸ entities';
echo json_encode($s);
You'll see the only thing PHP does is to add double quotes around the string.
Solution 2
json_encode
does not do that. You have another component that is doing the HTML encoding.
If you use the JSON_HEX_
options you can avoid that any <
or &
characters appear in the output (they'd get converted to \u003C
or similar JS string literal escapes), thus possibly avoiding the problem:
json_encode($s, JSON_HEX_TAG|JSON_HEX_AMP|JSON_HEX_QUOT)
though this would depend on knowing exactly which characters are being HTML-encoded further downstream. Maybe non-ASCII characters too?
Solution 3
Based on the manual it appears that json_encode shouldn't be escaping your entities, unless you explicitly tell it to, in PHP 5.3. Are you perhaps running an older version of PHP?

I send
json_encoded
data from my PHP server to iPhone app. Strings containing html entities, like'&'
are escaped byjson_encode
and sent as&
.I am looking to do one of two things:
make
json_encode
not escape html entities. Doc says 'normal' mode shouldn't escape it but it doesn't work for me. Any ideas?make the iPhone app un-escape html entities cheaply. The only way I can think of doing it now involves spinning up a
XML/HTML parser
which is very expensive. Any cheaper suggestions?
Thanks!
