For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Thank you for your interest in PHP. read the docs @ php.net/empty again. ------------------------------------------------------------------------ [2003-01-29 07:59:20] verx at implix dot com $array1 = array ("a" => "green", "red", "blue"); $array2 = array ("b" => "green", "yellow", "red"); if (false == empty(array_intersect ($array1, $array2))) { echo 1; } Log output: PHP Parse error: parse error, unexpected T_STRING, expecting T_VARIABLE or '$' in /var/www/test/arint.php on line 6 line 6 is the line with IF statement. However the following code works perfectly: $array1 = array ("a" => "green", "red", "blue"); $array2 = array ("b" => "green", "yellow", "red"); $result = array_intersect ($array1, $array2); if (false == empty($result)) { echo 1; } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=21942&edit=1
