bugs and a leak

I'm not sure if these are bugs or if I'm just expecting too much... Using RC1. First problem I've noticed is that fread($fp, -128) does not move the offset at all, much less to 128 bytes from the end... Shouldn't this work? Second, there seems to be inconsistency in the way php deals with hex. For example, php does not consider 0xff and ff to be equal. Shouldn't PHP ignore the 0x when doing a comparison? I noticed this reading a byte from a file which had the value 0xff, however php stores it as just ff and doing a comparison between the read byte and 0xff failed when they should both have the same value. In other words, if the first byte of a file is 11111111 and I do $fp = fopen($file, "r"); $byte = bin2hex(fread($fp, 1)); $byte == 0xff ? print "Yep" : print "Nope"; This will output Nope even though they are the same value. Also, if $byte is read from a file to and converted to hex for the value ff, the following two things do not do the same thing $byte &= f0; $byte &= 0xf0; The first one, while giving the correct answer, issues the following zend_execute.c(1937) : Freeing 0x08142B2C (3 bytes), script=./test.php zend_variables.c(125) : Actual location (location was relayed) The second one, while not giving the correct answer, does not leak. Should not both of these do the same thing (without leaking memory..)? -- Chad Cunningham ccunning@math.ohio-state.edu Only 159 days until RSA Patent expiration!
