It should be noted that a static variable inside a method is static across all instances of that class, i.e., all objects of that class share the same static variable. For example the code: <?php class test { function z() { static $n = 0; $n++; return $n; } } $a =& new test(); $b =& new test(); print $a->z(); // prints 1, as it should print $b->z(); // prints 2 because $a and $b have the same $n ?> somewhat unexpectedly prints: 1 2 ---- Manual Page -- http://www.php.net/manual/en/language.variables.scope.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+53915 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+53915&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+53915&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+53915&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+53915&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+53915&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+53915&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+53915&report=yes Search -- http://master.php.net/manage/user-notes.php
