I can't see why you *have* to use file_get_contents() have you tried filesize() and chcked the result is less than memory_limit? > (This should be the fastest way for this task says the manual... right!) > > The problem is, that if the memory_limit in the php.ini is set to 64MB, and > the file read in by file_get_contents is bigger than 64MB, file_get_contents > crashes without an EXCETPION. This crash cant be catched! why do you think it should throw an exception? it won't, especially not a particular class of exception that you made up o the spot. php errors and exceptions are 2 different things, before going any further you should read up on both so that you understand the difference. > > I want handle this this way: > > try{ > $data = file_get_contents($file); > } > catch (MemoryLimitReachedException $e){ > // try the same using a while loop reading the data!
