Using regex in php to just select and echo out persian chars

Question

I have a string like this :

این یafsک رشsegته می y34باشد

Specially , i want a function (like regex) to echo out JUST persian chars.

So , the out put should be :

این یک رشته می باشد

I have found we can use below regex, but i can't use it with function, it does not work.

regex i tried:

preg_match("(^[\x{0600}-\x{06FF}]*$)", $title);

error : Compilation failed: character value in \x{} or \o{} is too large at offset

What can i do and what should i do ?

Tnx.

سلام عزیزم

$string = preg_replace("/[a-zA-Z0-9]/", "", $string);

You can simply remove all English alphabetical characters and all numbers from the string

OR : you can do it reverse :

$string  = preg_replace("/[^ الف-ی]/i", "", $string);

This will remove all characters except Persian chars , This way you can remove all persian numbers too : d

Answer 2

You need to enable UTF-8 on the pattern to use the “higher” unicode range in a regex:

preg_match("/^[\x{0600}-\x{06FF}]*$/u", $title);

Note the u modifier after the closing delimiter.

Answer 3

Try this one:

preg_match("/^[الف-ی]*$/u", $title);
