RE: [PHP-DB] Direct Access to an Array Item?
Perhaps you could elaborate on the exact motive
Say, why would you be checking against the 4th element of an array.
I could understand why you would want to check every element of an array
against a particular value, but why just the 4th element, just for interest.
In response to your question, there wasn't a way to access the index of an
array using the square bracket, but you could explore the various array
functions available in php. If you have a dynamic variable/counter, you
could instead use each() or next()
For instance,
You can get this to work
$str = "123#456#789";
"123" == current(explode('#', $str))
The result will be true.
Not sure if this helps you, but worth a shot.

i don't think it is possible to do such syntax. nor theres a work around on
to make it way you want it. (i'm not an expert. just IMHO)

Closest you might get is
if ( mysql_result($result,0,3 ) == 'foo') {
$user = $mysql_fetch_row($result);
}

PHP does not currently support this type of syntax in any form. You must
assign the return value of a function to a variable if you want to
access it as an array.

use mysql_result
mysql_result ( $result, 0, 2 )
where 2 is the offset of the fields in the row
