php - Need assistance with regexp and cyrillic -

i´ve got next problem

i have regular look did not made myself:

"|(?!<.*?)\b$old_text\b(?![^<>]*?>)|s"

it wonderfully finds $old_text in $text

but if $old_text illustration

"ОртоЦентр"

it wont find it

i´m sure /b boundaries reffering

regular look cyrillic alphabet

so tried adapt

\[wа-я]+$old_text\[wа-я]+

or

\wа-я$old_text\wа-я

also tried sth. using unicode range:

|(?!<.*?)\x{0410}$old_text\x{042f}(?![^<>]*?>)|

also tried cyrillic thing i´m sur i´m not using correct:

"|(?!<.*?)\b{cyrillic}$old_text\b{cyrillic}(?![^<>]*?>)|si"

maybe rather right direction ? hey dont work, can genius pls. assist me ? in advance

update:

"|(?!<.*?)\p{cyrillic}+\b$old_text\b(?![^<>]*?>)|si"

update, heres php-code:

$text = "bar foo <p> barfoo </p> foobar ОртоЦентр bar bar"; $old_text = "ОртоЦентр"; $new_text = '<a href="http://foo.bar">ОртоЦентр</a>'; $limit = '-1'; $replaced = preg_replace( "|(?!<.*?)(\p{cyrillic}+$old_text\b)(?![^<>]*?>)|si", $new_text, $text, $limit );

as understand question, want replace such ОртоЦентр aaaОртоЦентрzzz <a href="http://foo.bar">...</a> ... matching word.

from inital regex looks should done "outside tags".

to work unicode need specify u (pcre_utf8) modifier. both, pattern , input expected valid utf-8 then. next illustration uses i caseless modifier.

would skip tags: <[^>]*>(*skip)(*f) or | match word * amount of \p{l} unicode letters before , after: \b\p{l}*word\p{l}*\b , capture. sample-pattern be:

~<[^>]*>(*skip)(*f)|\b(\p{l}*ОртоЦентр\p{l}*)\b~ui

test @ regex101.com (see explanation on right side)

and php-sample variables:

$txt = "bar foo <p> barfoo </p> foobar aОртоЦентрz bar bar"; $w = "ОртоЦентр"; $s = '~<[^>]*>(*skip)(*f)|\b(\p{l}*'.preg_quote($w,'~').'\p{l}*)\b~ui'; $r = '<a href="http://foo.bar">\1</a>'; $replaced = preg_replace($s, $r, $txt);

test @ eval.in
