Re: [PHP] foreach fails on unitialized array?
I would expect foreach to treat an unitialized variable as an empty
array and hence do nothing. Is this the expected behaviour?
if(is_array($myvar)) foreach($myvar as $key = $value ) {
...
}
other possibility, so that the foreach is run each time (and it doesn't
affect the source code, you can put it wherever you want) :
if(!is_array($myvar)) {
$myvar = array();
}
regards !

[PHP] foreach fails on unitialized array?
When I use foreach on a uninitialized array I get the following warning: Warning: Invalid argument supplied for foreach() in /www/htdocs/jc/cart/add_item.php on line 21 I would expect foreach to treat an unitialized variable as an empty array and hence do nothing. Is this the expected behaviour? Thanks, Jc -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

It's always been my experience. I just get in a habit of doing this:
if(is_array($myvar)) foreach($myvar as $key = $value ) {
...
}
