Something like "WHERE" from SQL
|
|
| Kenoli 2006-11-23, 6:58 pm |
| Is there a way to accomplish something like the "WHERE" syntax from SQL
in php? For example an equivalent to the following, which I know is
not proper php syntax.
foreach ($var as $key => $value WHERE $key != '3') {
echo "$key is $value";
}
or
implode (",", $_POST WHERE $_POST[name] != 'post');
I keep wanting to be able to do things like this.

array_filter();

The problem here is you cannot filter on keys.
On could use array_keys(), array_filter() and then again array_flip() and
array_intersect_keys(). It's hardly better then a foreach loop however, and
a lot less readable.
