Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php It returns 1 as that means you have one element. Anyway this is the expected behavior and used by all our users for about 10 years now. Changing this will break most PHP applications out there. Further more the scenarios shown should use is_array() and family of funtions. Previous Comments: ------------------------------------------------------------------------ [2008-07-16 00:32:21] [EMAIL PROTECTED] Seems odd why its coded to return 1 imo, heres a patch against latest PHP_5_3 cvs that changes this to return false: http://www.phpfi.com/332583 ------------------------------------------------------------------------ [2007-12-08 20:30:47] warren at transfusionmedia dot com Description: ------------ When doing count($var) where $var is not an array, the return = 1. The problem is when you're doing a check in your code: if (count($var) > 0){ //do something } This will evaluate as true if $var is not an array. This is a problem if you are doing this: if (count($var) > 0){ sort($var); // anything that requires $var to be an array } If there is anything in that if statement that requires $var to be an array, there will be a fatal error. I know you can also add an is_array check in there, but that is non-obvious and shouldn't be necessary. Really, if $var is not an array, count($var) should return false or null, or at least a -1 Reproduce code: --------------- $var = "foo"; if (count($var) > 0){ sort($var); } else { echo "The value of var is not greater than zero"; } Expected result: ---------------- The value of var is not greater than zero Actual result: -------------- Warning: sort() expects parameter 1 to be array, string given ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=43538&edit=1
