Question

I need to match a string that contains only Cyrillic letters so I try this:

<?php  
$pattern="#[x\{0410}-x\{042F}]#u";  
$string="АФ";  
echo preg_match ($pattern,$string);  
?>  

But I get this error

Warning: preg_match(): Compilation failed: range out of order in character class at offset 10 in /home/ge0rgi/www/preg.php on line 4

Answer 1

$pattern= "#[\x{0410}-\x{042F}]#u"; 

Returns 1 but doesn’t match F…

Array
(
    [0] => А
)
