The previous patterns didn't capture a quote that precedes words other
than The/A/An. Here is another pattern:
'/^ *((The|An?) +|")+/i'
'/^ *(The +|An? +|")+/i'
It looks like yours, but adds a plus after the parentheses, meaning that
the things in the parentheses can appear once or more times.
Alternatively, if the pattern becomes or feels too complex, you can
separate it in different patterns that will be replaced one after
another. In this case place the two patterns in array(...):
'preg_replace(array("/^ *\"/", "/^ *(?:The|An?) /i"), "",
(@$page["title"] ? $page["title"] : $AsSpacedFunction($name)), 1)';
Wow that actually looks more complex than the combined pattern! :-)
