String Search for Quotations ? \" ?

[soma56]

Does/can php reconize quotations beyond the simple example I have below:

 

$quote = "\"";

if(strstr($test, $quote)){
echo "quote found";
}

 

I'd like to detect any instance of a quote. Should I be including html such as " and/or other html quote symbols? Or does the simple example I have above suffice?

I'm going through one of those moments where everything logically looks like it should work but it isn't. I have a textarea box that is posting text that contains quotes.

 

The quotes are slipping through my filters. By all accounts should the following code grab any instance of a quotation mark in the manner that I have described?

 

strpos($string,'"') || $string == '"'

 

Note: the above code contains a " between two single quotes.
