ID: 6741 User Update by: ping@alt.it Status: Analyzed Bug Type: Documentation problem Description: gettype of 'user function' returns null more examples: <? $z=33; function normal() { $a=1; } class class1 { function classfunction1() { $b=2; } } $myclass=new class1; echo "myfunction is of type ", gettype($myclass->classfunction1),"<br>\n"; echo "b is of type ", gettype($myclass->b),"<br>\n"; echo "z is of type ", gettype($z),"<br>\n"; echo "normal is of type ", gettype($normal),"<br>\n"; echo "class1 is of type ", gettype($class1),"<br>\n"; echo "myclass is of type ", gettype($myclass),"<br>\n"; echo "classfunction1 is of type ", gettype($classfunction1),"<br>\n"; ?> this piece of code, run both on PHP 3.0.12 and PHP 4.0.2 gives these different results: ouput by PHP 3 .0.12: myfunction is of type user function b is of type string z is of type integer normal is of type string class1 is of type string myclass is of type object classfunction1 is of type string output by PHP 4.02: myfunction is of type NULL b is of type NULL z is of type integer normal is of type NULL class1 is of type NULL myclass is of type object classfunction1 is of type NULL Previous Comments: --------------------------------------------------------------------------- [2000-09-25 16:41:48] ping@alt.it The doc at http://www.php.net/manual/function.gettype.php says: > gettype -- Get the type of a variable > Description > string gettype (mixed var) > Returns the type of the PHP variable var. > Possibles values for the returned string are: > "boolean" > "integer" > "double" > "string" > "array" > "object" > "resource" > "user function" > "unknown type" I wonder what happens with other types as 'object' or 'resource' Anyway the string 'NULL' doesn't seem to be among the possible returned values. --------------------------------------------------------------------------- [2000-09-23 22:26:27] stas@php.net I don't see any mention in the manual that gettype should work on functions - only on variables. In fact, it cannot veen return "user function" now, so I put it in doc's problem. --------------------------------------------------------------------------- [2000-09-20 05:23:16] ping@alt.it It WAS undocumented but working on php3. It IS documented and doesn't work on php4 <? class class1 { function classfunction1() { $b=2; } } $myclass=new class1; echo "classfunction1 is of type ", gettype($myclass->classfunction1),"<br>n"; ?> --------------------------------------------------------------------------- [2000-09-16 18:21:49] stas@php.net Please provide a code example. Also, I guess you should never rely on undocumented behaviour to preserve, anyway. --------------------------------------------------------------------------- [2000-09-13 19:16:44] ping@alt.it gettype() on function names returns null Although undocumented, in version 3 it properly returned 'user function'. --------------------------------------------------------------------------- The remainder of the comments for this report are too long.
