No, but if you want them to be compared as strings, just cast to a
string then, or use a strcmp() call. PHP can't read your mind.

I do understand that time has fixed this "feature".
As for explicit casting, it does result in different behaviour, when
comparing string/values.
$x = '0xF';
$y = (int)$x;
echo($x == 15 ? 'YES' : 'NO');
echo('<br />');
echo($y == 15 ? 'YES' : 'NO');
Outputs:
YES
NO
Strict equivalence testing doesnt help when you wish
"1234" and 1234 to be considered equal.

That's why you have the === operator. "12345aaaa" has always evaluated
to 12345 when cast to an integer and it always will. That also means
that it must be equivalent to 12345 when used in an integer comparison.
You need to be explicit in your comparisons and use explicit casting
elsewhere.

The documentation does not help.
a string containing a beginning with a numeric character, but also
containing non-numerics surely should not be cast to an integer before
comparision?
I understand that "12345" == 12345 but the string "12345xxx" isnt
12345.

See these manual pages:
http://www.php.net/switch
http://www.php.net/manual/en/types.comparisons.php
Maybe the manual should explain this a bit better.

How's this for an impossibility..
echo('a' != 0 ? 'TRUE' : 'FALSE');
echo('<br />');
echo('a' ? 'TRUE' : 'FALSE');
Outputs:
FALSE
TRUE
