PHP How to determine if a word is between two open quotes in a string?

I have this function to determine if a word is between single/double quotes but it gives a false positive if the word is between two closed quotes.

function keyword_in_quotes( $str, $word ) {
    echo $str . "\n";
    if (preg_match('/["\'].*\b' . $word . '\b.*["\']/m', $str))
            echo $word . " found in quotes.\n";
    else
            echo $word . " NOT found in quotes.\n";
}

// this call correctly reports KEYWORD is between quotes
keyword_in_quotes( "Sentence with a 'Specific KEYWORD and other words' in quotes", "KEYWORD" );

// this call incorrectly reports KEYWORD is between quotes
keyword_in_quotes( "Sentence with a 'lead quote' and KEYWORD not in 'quotes' or 'even this'", "KEYWORD" );

Which gives the results:

Sentence with a 'Specific KEYWORD and other words' in quotes
KEYWORD found in quotes.
Sentence with a 'lead quote' and KEYWORD not in 'quotes' or 'even this'
KEYWORD found in quotes.

I'm a bit out of my depth. How can I determine if the given word is only between OPEN quotes? (No limit on number of quotes in the string).

You can use this regex instead to determine if KEYWORD is not in quotes:

'[^']*'(*SKIP)(*F)|KEYWORD
