I'd say silently ignoring it and moving along is fine here. Only if the var IS_NULL, but this is the case. So I'm +1. On 25.10.2005 02:22, Marcus Boerger wrote:
Hello internals, i would like to change foreach a tiny bit. Actually i don't like the warning when using foreach with null. marcus@zaphod /usr/src/php-cvs $ php -r '$n=NULL; foreach($n as $v);' make: `sapi/cli/php' is up to date. Warning: Invalid argument supplied for foreach() in Command line code on line 1 marcus@zaphod /usr/src/php-cvs $ php -r 'foreach(NULL as $v);' make: `sapi/cli/php' is up to date. Warning: Invalid argument supplied for foreach() in Command line code on line 1 The way we use NULL in PHP should result in no warning here. The patch for this can be found here: http://php.net/~helly/php/ext/ze2/ze2-foreach-null-20051025.diff.txt It was made with head but applies to 5.1 as well. Any opinions?
