Req #67734 [NEW]: Add output escaping specifiers to sprintf etc.

From: marcus at synchromedia dot co dot uk Operating system: PHP version: Irrelevant Package: Strings related Bug Type: Feature/Change Request Bug description:Add output escaping specifiers to sprintf etc. Description: ------------ sprintf, vsprintf etc have numerous different specifiers for numbers, but only a single generic 'string' option for strings with %s. It would be useful to have additional options for escaping values, for example with URL encoding or HTML escaping. You might say that you can achieve this by applying escaping functions to the variables you pass in, which is correct, but in the interests of DRY, it's much tidier if the printing function can do this itself - and after all there is a clear precedent in the form of all the numeric options for which you could say the same. It might be interesting to provide SQL escaping specifiers, since PDO doesn't provide a complete implementation for this, thoughit may be difficult to pass in a connection reference in a clean way. Test script: --------------- The current implementation looks like this: echo sprintf('<a href="%s?linkname=%s">%s</a>', 'myscript.php', rawurlencode('> my link'), htmlentities('> my link', ENT_QUOTES)); Assuming the %h specifier applies URL-encoding, and the %H specifier applies HTML escaping: echo sprintf('<a href="%1$s?linkname=%2$h">%2$H</a>', 'myscript.php', '> my link'); Result: <a href="myscript.php?linkname=%3E%20my%20link">&gt; my link</a> -- Edit bug report at https://bugs.php.net/bug.php?id=67734&edit=1 --
