strtok — Tokenize string
$str
, string $token
) : string$token
) : string
strtok() splits a string (str)
into smaller strings (tokens), with each token being delimited by any
character from token.
That is, if you have a string like "This is an example string" you
could tokenize this string into its individual words by using the
space character as the token.
Note that only the first call to strtok uses the string argument. Every subsequent call to strtok only needs the token to use, as it keeps track of where it is in the current string. To start over, or to tokenize a new string you simply call strtok with the string argument again to initialize it. Note that you may put multiple tokens in the token parameter. The string will be tokenized when any one of the characters in the argument is found.
strThe string being split up into smaller strings (tokens).
token
The delimiter used when splitting up str.
A string token.
Example #1 strtok() example
<?php
$string = "This is\tan example\nstring";
/* Use tab and newline as tokenizing characters as well */
$tok = strtok($string, " \n\t");
while ($tok !== false) {
echo "Word=$tok<br />";
$tok = strtok(" \n\t");
}
?>
Example #2 strtok() behavior on empty part found
<?php
$first_token = strtok('/something', '/');
$second_token = strtok('/');
var_dump($first_token, $second_token);
?>
Exemplul de mai sus va afișa:
string(9) "something"
bool(false)
Această funcție poate întoarce valoarea Boolean FALSE, dar poate de
asemenea întoarce o valoare non-Boolean care evaluează în FALSE. Vă rugăm să
citiți secțiunea despre tipul Boolean
pentru informații suplimentare. Utilizați
operatorul === pentru a
verifica valoarea întoarsă de această funcție.
