htmlentities not working on single quote

Question

I am trying to do a simple convert of single quote ( ' ) to html entity ( ' ) but can not figure out why this is not working.

$test = "Bob's House";

echo htmlentities($test,ENT_QUOTES);

echo htmlspecialchars($test,ENT_QUOTES);

Both examples still return: Bob's House

I have tried a combination of flags: ENT_IGNORE, ENT_SUBSTITUTE, etc with no success.

I suspect it has something to do with my charset. If so how do I display my default charset & alter it for this seemingly simple code to work.

Answer 1

It is working. You are outputting Bob's House (or similar).

But since you're in a browser, it sees the ' and replaces it with ' .

Want proof? Right-click and View Source.

More proof? echo strlen($test) . " -- " . strlen(htmlentities($test,ENT_QUOTES));
