Using PHP to decode a string

Question

I'm trying to decode a string using PHP but it doesn't seem to be returning the correct result.

I've tried using html_entity_decode as well as utf8_decode(urldecode())

Current code:

$str = "joh&#039;@test.com";
$decodeStr = html_entity_decode($str, ENT_COMPAT, "UTF-8");

Expected return is [email protected]

how did you encode it ? It seems your original string was joh'@test.com. — Istiaque Ahmed

It was encoded by the cms that I'm using - im not sure of the specifics of the encoding. — Stephanie Parker

I suppose your html entity code for character 'n' is wrong. Working example:

$str = "joh&#110;@test.com";
echo $decodeStr = html_entity_decode($str, ENT_COMPAT, "UTF-8");

Thanks for the reply - no it's correct that it should be an apostrophe.

If "it's correct that it should be an apostrophe", how do we interpret your "Expected return is [email protected]"?

The HTML entity code for n is n, whereas the entity code in your string is for a single apostrophe '. If you wanted to convert single quotes, the ENT_QUOTES flag must be used when calling html_entity_decode(), as the default is ENT_COMPAT | ENT_HTML401 (from the PHP docs) which doesn't convert single quotes. If you need additional flags, you can "add" them using the pipe | symbol like this: ENT_HTML401 | ENT_QUOTES.

If you're expecting [email protected]:

$str = "joh&#110;@test.com";
$decodeStr = html_entity_decode($str, ENT_COMPAT, "UTF-8");
echo $decodeStr;  // [email protected]

Or if you're expecting joh'@test.com:

$str = "joh&#039;@test.com";
$decodeStr = html_entity_decode($str, ENT_QUOTES, "UTF-8");
echo $decodeStr; // joh'@test.com

Shouldn't the entity for @ be @ instead of ' which is for an apostrophe?
