According to operators precedence table, "++" operator precedence is MUCH MORE higher then "+" one. As i understand, exactly pre-increment, because post- increment is always executed last one (table with precedence order is not correct, eh? do we need to separate pre-increments and post-increments there?) 2. According to http://www.php.net/manual/en/language.operators.increment.php page, there should be following scenario for your example: - $a variable is pre-incremented (becomes $a = 2) - sum is calculated for $a + $a variables (4 number will be printed by echo) - $a variable is post-incremented (becomes $a = 3) Test script: --------------- // mixing ++ and + produces undefined behavior - WTF? result should always be 4 $a = 1; echo ++$a + $a++; // may print 4 or 5 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=65087&edit=1
