双引号的str_replace根本不起作用

I've used str_replace for many characters and it works perfectly. For the life of me it does not work with double quotes. It simply doesn't do anything:

$value = str_replace('"', '', $value);

This does not remove double quotes. Is there some Apache or PHP setting that stops this from working?

Edit: trim($value, '"') also does not work! I think i'm going mad.

Edit 2: AbraCadaver got it! Thanks it needed "

$value = str_replace(""", "", $value);

Thanks AbraCadaver

You can use that, but first convert the quotes you have which are non-ASCII "curly" quotes to ASCII quotes with this:

$content = iconv("UTF-8", "cp1252//TRANSLIT", $content);

See also: Can I use iconv to convert multi-byte smart quotes to extended ASCII smart quotes?

Just reiniterating what someone else suggested, as it worked for both me and the original poster:

$value = str_replace(""", "", $value);

Although, I was dealing with a single quote issue. What is odd is that the output from my php variable produced a ' in the code, not a &apos;. If it were &apos; that output, it wouldn't break the html attribute I was loading it into. Example: <element attr='&apos;'>

Not sure myself how to explain. But, glad it got fixed. Hope the original question gets upvoted as it seems not trivial or without effort, but a confusing situation and understandably so.

Here's a related gotchya. I was searching for id=" based on what Chrome DevTools was showing, that being id="identifier"

After loads of time wasted, I did View Source. The generated code was surrounded by single quotes, not double, i.e. id='identifier'
