belliash	d819820798	Always make an array copy. Fixes #48.	2019-04-20 07:19:35 +02:00
belliash	e794ffd97b	Fix PH7_HashmapDup(). ... This function needs to store the next index. Otherwise it will start to count from beginning, duplicating existing keys.	2019-04-19 20:16:42 +02:00
belliash	a0405f2267	Always perform type validation when inserting value to an array.	2019-04-19 07:08:29 +02:00

belliash	9a82298451	Do not check parameters passed to constructor. ... There is no need to check parameters passed to constructor and emit a notice, because PH7_VmCallClassMethod() does the job. It tries to find a matching method if overloaded and checks all arguments passed. In case of any problems, it emits E_ERROR.	2019-04-17 12:18:55 +02:00
belliash	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.
