Description: ------------ Suppose we have a float value: $value = 345.332 and we want to use this value as an array key: $array[$value] = $value. This will cause that key will be truncated to integer 345 not to string "345.332". It is written in the manual that: "...A key may be either an integer or a string. If a key is the standard representation of an integer, it will be interpreted as such (i.e. "8" will be interpreted as 8, while "08" will be interpreted as "08")..." >From this point of view floats should be converted to strings. I'm not saying that this is a bug, rather I would like to be sure if this is a proper behavior. Simple solution is to type cast float value to string (string), but we have to know that given value is a float (and sometimes, we don't know that). IMHO any other type than integer should be treat as string. Reproduce code: --------------- $value = 345.654; $array = array(); $array[$value] = "Float"; Expected result: ---------------- array ( "345.654" => "Float" ) Actual result: -------------- array ( "345" => "Float" ) -- Edit bug report at http://bugs.php.net/?id=32671&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=32671&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=32671&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=32671&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=32671&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=32671&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=32671&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=32671&r=needscript Try newer version: http://bugs.php.net/fix.php?id=32671&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=32671&r=support Expected behavior: http://bugs.php.net/fix.php?id=32671&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=32671&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=32671&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=32671&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=32671&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=32671&r=dst IIS Stability: http://bugs.php.net/fix.php?id=32671&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=32671&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=32671&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=32671&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=32671&r=mysqlcfg
