Question

I looked at the other question, but the answer is not true for me.

$text:

(string:104) “The diamond cannot be polished without friction, nor the man perfected without trials.” Chinese Proverb

Yet…

strpos($text, '“')

=== false, upon inspection.

Same with:

strpos($text, "“")
strpos($text, "\“")
strpos($text, '\“')

Ideas?

EDIT: it is a $_POST variable grabbed from a textarea, if that makes a difference. The value is precisely

“The diamond cannot be polished without friction, nor the man perfected without trials.” Chinese Proverb

Answer 1

Perhaps the quote character “ found in the text is a different Unicode character to the one you are specifying in your code. Alternatively, perhaps the text is in a different character encoding to your code. Check what character set you are viewing the output in, and see whether it matches the encoding of the PHP script.

Edit:

function str_ord ($str) {
    $len = strlen($str);
    $my_array = array();
    for ($i = 0; $i < $len; ++$i) {
        $my_array[] = ord($str[$i]);
    }
    return implode(' ', $my_array);
}

Find out what str_ord() outputs for '“' and for the first few characters of your textarea-string. If it outputs different numbers then you have a character encoding issue.
