#28683 [Opn->Csd]: addcslashes ASCII character conversion octal range invalid

ID: 28683 Updated by: dave@php.net Reported By: todd at magnifisites dot com -Status: Open +Status: Closed Bug Type: Documentation problem Operating System: RH Linux/Windows XP PHP Version: 4.3.6 New Comment: This bug has been fixed in the documentation's XML sources. Since the online and downloadable versions of the documentation need some time to get updated, we would like to ask you to be a bit patient. Thank you for the report, and for helping us make our documentation better. I only saw one error in the documentation and have fixed it. Remember that octal representation is base 8, not base 10. \36 is not the '$' character, it is ASCII character 30, which is why your expected result and all its \<digits> are wrong.

It then instructs us to use the ord() function to find the ASCII value for a character. I have found discrepancies in my tests (I've tested on both Linux and Windows servers). The octal representation conversion seems to occur completely throughout the range including 32 through 126, inclusive, rather than outside that range. Reproduce code: --------------- $null = NULL; $var = "Hi there\" dollar $ amper \t sand & and single ' quote NULL $null"; $escaped_var = addcslashes($var, "\0\9\34\36\38\39"); print $escaped_var; Expected result: ---------------- Hi there\" dollar \$ amper \t sand \& and single \' quote NULL Actual result: -------------- Hi there" dollar $ amper sand & and single ' quote NULL ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=28683&edit=1
