strpbrk

    (PHP 5, PHP 7, PHP 8)

    strpbrk — Ricerca in una stringa uno qualsiasi dei caratteri di un dato set

    Descrizione

    strpbrk(string $haystack, string $char_list): string

    strpbrk() cerca nella stringa haystack i caratteri indicati in char_list, e restituisce una stringa a partire dal carattere trovato (oppure false se non ve ne sono).

    Nota:

    char_list distingue tra maiuscole e minuscole.

    Example #1 Esempio di uso di strpbrk()

    <?php

    $text     = 'This is a Simple text.';

    // visualizza "is is a Simple text." because 'i' is matched first
    echo strpbrk($text, 'mi');

    // visualizza "Simple text." because chars are case sensitive
    echo strpbrk($text, 'S');
    ?>

    If you're not looking to duplicate the rest of the string, but instead just want the offset, in the spirit of the str*pos() functions, use strcspn()

    A little modification to Evan's code to use an array for the second parameter :<?phpfunction strpbrkpos($s, $accept) {  $r = FALSE;  $t = 0;  $i = 0;  $accept_l = count($accept);  for ( ; $i < $accept_l ; $i++ )    if ( ($t = strpos($s, $accept[$i])) !== FALSE )      if ( ($r === FALSE) || ($t < $r) )        $r = $t;    return $r;}?>
