Re: New escaped output operator

> "Use '<?~' and it will solve your XSS and other escaping problems with outputting HTML that was stored in a DB." I don't think this is a good phrase for documentation. This form should be considered exactly as htmlspecialchars, with taking into account any language and encoding-specific issues, and this should be pointed in documentation. This is a shorcut for often operation, like '??' for isset() check. And it can really improve security, not in 90% but about 99.9999% cases. 2016-06-20 4:41 GMT+05:00 Walter Parker <walterp@gmail.com>: > >> >> > where getting it 90% correct is worse that not doing anything at all. >> > Things like this will cause people to be blindsided when the uncaught >> escapes >> > cause the next major security problem. >> >> Why do you think so?
