Rafal Kupiec	ab8bf48485	Make constant declarations local. ... There are several changes in this commit: * first of all constants declared by 'const' statement should be local (declared in current scope / frame), * constants are declared by using OP_DECLARE instruction, * OP_LOADC browses both global and local constants container, * PH7_VmRegisterConstant() allows both global and local declarations. Since this commit, there are 3 kinds of constants: 1) global 2) local (in loop, closure, method) 3) class members. Actually there is no way to declare a global constant except the built-in constants.	2019-05-04 13:45:32 +02:00
Rafal Kupiec	e6b7f1be2c	Always emit OP_JMPLFE as goto can be used inside a loop and frame has to be left.	2019-05-03 10:55:57 +02:00

Rafal Kupiec	4d8d92092e	Refactor foreach() loop. ... In AerScript, the foreach() loop is syntatically more similiar to C#, than PHP. However the optional '$key => $value' construct is still available, because arrays in AerScript are still a hashmaps.	2019-04-30 23:38:59 +02:00

Rafal Kupiec	48a38dc1af	PH7_GenCompileError() always breaks script execution on E_ERROR. ... Thus code placed below will never get executed and is completely useless.	2019-04-24 23:12:59 +02:00

Rafal Kupiec	bd22425b46	Do not allow 'continue' statement in a switch case. ... Important rule while using continue statement is that, We can use continue statement only within the loops. Switch case is conditional block not a loop so we cannot execute the continue statement inside switch.	2019-04-17 11:13:29 +02:00
