匹配重音字符的快捷方式

Question

In regex, there are shortcuts, like \\w or az .

In the same way, is there an alternative to writing all wanted accented symbols (for instance, transforming [éèàêâûôîùÈ...] into \\ê )?

Answer 1

For example:

$t = "Normal text éèàêâûôîùÈ more text";

preg_match_all('/[^\P{Latin}\x00-\x80]+/u', $t, $m);
print_r($m);

Result:

Array
(
    [0] => Array
        (
            [0] => éèàêâûôîùÈ
        )

)

Basically, this selects all "latin" characters (=letters), except those in the lower ascii range (=a..z). Not sure if this can be called a "shortcut" though ;)
