How to convert PHP regex to match Arabic characters to JS regex

Question 1

I have this English and Arabic regex in php , it works fine with php

But its not working with this library Formvalidation.io

~^[a-z0-9?-?-+,()/'sp{Arabic}]{1,}$~iu

I need to make it work and convert into JS regex to use in formvalidation regex.

Question 2

The Arabic regex is:

[u0600-u06FF]

Actually, ?-? is a subset of this Arabic range, so I think you can remove them from the pattern.

So, in JS it will be

/^[a-z0-9+,()/'su0600-u06FF-]+$/i

See regex demo

Question 3

"/<script((?:(?!src=).)*?)>(.*?)</script>/smix"

(My first look-ahead regex ;))

Please note that you should not parse HTML with regexes, see:

Question 4

JavaScript uses the syntax uhhhh (exactly 4 hexadecimal digits) to specify an UTF-16 code unit in the regular expression. For characters in BMP range, except for the range D800-DFFF, the code point of the character maps directly to one UTF-16 code unit which has the same value of the code point. This is exactly the case here, so we don't need to deal with surrogate and its quirks.

In this case, just replace x{h...hh} syntax from PCRE (in PHP) with uhhhh syntax:

var PREG_CLASS_UNICODE_WORD_BOUNDARY = [
    "\u0000-\u002F\u003A-\u0040\u005B-\u0060\u007B-\u00A9\u00AB-\u00B1\u00B4",

Question 5

Nothing really special. PHP regex syntax is very much the same as in JavaScript:

str = str.replace(/(d*)|/(P)//g, "");

You can find more information about regular expressions in JavaScript in this manual from MDN: https://developer.mozilla.org/en-US/docs/JavaScript/Guide/Regular_Expressions.
