#32529 [NEW]: bsprintf?

From: andala at gmail dot com Operating system: MacOS X PHP version: 5CVS-2005-04-01 (dev) PHP Bug Type: Feature/Change Request Bug description: bsprintf? Description: ------------ Not sure how open you are to feature requests like this. I use my own function bsprintf() (i.e. boolean sprintf) quite a bit for display code. What it does is return $var outputted according to $format *only* if $var is not empty, otherwise return nothing. If (optional) $default is passed in, $default is returned instead of nothing if $var is empty. function bsprintf($var,$format='%s',$default="") { if (!empty($var)) {return sprintf($format,$var);} else if (!empty($default)) return $default; }; Thought I'd suggest implementing something like this as a built-in function. Here is a brief example of the type of use that I've found useful, mostly to keep code simple, condensed, and readable (especially with long scripts): ---- USING bsprintf ----- $apples=100; echo "% Apples: ".bsprintf($apples,'%s%%',"None.")." / % Oranges: ".bsprintf($oranges,'%s%%',"None."); (Total lines: 2) Returns: % Apples: 100% / % Oranges: None. ---- NOT USING bsprintf ----- $apples=100; echo "% Apples: "; echo (!empty($apples)) ? $apples."%" : "None."; echo " / % Oranges: "; echo (!empty($oranges)) ? $oranges."%" : "None."; (OR) $apples=100; echo "% Apples: ".((!empty($apples)) ? $apples."%" : "None.")." / % Oranges: ".((!empty($oranges)) ? $oranges."%" : "None."); (Total lines: 5, or 2-- including a really ugly, hard to read one) Returns: same as above! -- Edit bug report at http://bugs.php.net/?id=32529&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=32529&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=32529&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=32529&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=32529&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=32529&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=32529&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=32529&r=needscript Try newer version: http://bugs.php.net/fix.php?id=32529&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=32529&r=support Expected behavior: http://bugs.php.net/fix.php?id=32529&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=32529&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=32529&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=32529&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=32529&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=32529&r=dst IIS Stability: http://bugs.php.net/fix.php?id=32529&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=32529&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=32529&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=32529&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=32529&r=mysqlcfg
