Official manual can be found here.

PHP regex match Latin words may contains symbols, digits and spaces

There are names of records in which are mixed Cyrillic and Latin words, symbols, spaces, digits, etc.

I need to preg_match (PHP) only Latin part with any symbols in any combinations.

Test set:

БлаблаБла Uty-223
Блабла (бла.)Бла CAROP-C
Бла бла ST.MORITZ
Бла бла RAMIRO2-TED
LA PLYSGNE 1 H - 001

(Блабла) – doesn’t matter Cyrillic words.

So i tried pattern:

/[-0-9a-zA-Z.]+/

But [Блабла (бла.)Бла CAROP-C] and [LA PLYSGNE 1 H – 001] not found as string.

Next i tried to write more flexible pattern:

/[-0-9a-zA-Z]+(?:.)?+(?:s+)?+[-0-9a-zA-Z]+/

But there is still problem with matching [LA PLYSGNE 1 H – 001].

Is there any idea how can this be solved?

Thanks.

    If the . and - can not occur at the beginning or end, you can start the match with [0-9a-zA-Z] and optionally repeat one of the chars listed in the character class followed by again [0-9a-zA-Z]

    b[0-9a-zA-Z]+(?:[.h-]+[0-9a-zA-Z]+)*b
    • The b is a word boundary preventing a partial word match
    • h matches a horizontal whitespace character

    See a regex101 demo.

    Matching at least a single char [0-9a-zA-Z] with allowed chars . and - in the whole string, and asserting whitespace boundaries to the left and right

    (?<!S)[.-]*b[0-9a-zA-Z](?:[0-9a-zA-Z.h-]*[0-9a-zA-Z.-])?(?!S)
    • Using (?<!S) and (?!S) are lookaround assertions that are whitespace boundaries, asserting not a non whitespace char to the left and the right.

    You can also use a script run starting with a latin letter:

    ~(*sr:p{Latin}.*S)~u
