You can't use "!" because it's not a valid special character in regular
expressions. It's really hard to craft do-not-match-this-word patterns.
You're better off separating the two pieces of logic.
$arr = array(
"abcd - rst",
"abcd - uvw",
"abcd - xyz",
"foobar - rst",
"blah - rst",
"googol - uvw"
);
reset($arr);
while (list($key, $value) = each($arr))
{
if (substr($value, 0, 5) != 'abcd ')
{
$arr[$key] = ereg_replace('^(.*) - .*$', '\1', $value);
}
}
print_r($arr);
