Arabic Alphanumeric with spaces only regex

Question

I want to know the equivalent of the following, but for Arabic alphabet only: ``` $regex = '[A-Za-z0-9-[\]_+ ]+' ``` I tried: ``` $regex = '[ا-ئ0-9 ]+'; ``` In which the first Arabic letter `ا` and the last one `ئ`. However, I have got the following error: ``` [phpBB Debug] PHP Warning: in file [ROOT]/includes/functions_user.php on line 1505: preg_match(): Compilation failed: range out of order in character class at offset 6 ```

Accepted Answer

You can check if your Regex flavour supports `\p{Arabic}` or `\p{InArabic}`

try:

```
$regex = '[\p{Arabic}\d-_+ ]+'
```
