例如：如果$ value ='home garden' code>或 $ value ='home，garden' code>， p>

我需要结果为 home-garden code> p>

我试过 $ result = preg_replace（'/ \ s + [\，] /'，' - '，trim（$ value）））; code>，但没有用.. p>

有人可以解释一下吗？ p> div>

答

$result = preg_replace('/[ ,]+/', '-', trim($value));

Test:

$value = '  home  ,garden , gardener  ';
$result = preg_replace('/[ ,]+/', '-', trim($value));

echo $result;
//home-garden-gardener

答

$result = str_replace(array(',', ' '), '-', $value);

答

    $stringAfter = str_replace(",", "-",$stringBefore);

    example:
    $stringBefore="abc,def,ghi";
    $stringAfter = str_replace(",", "-",$stringBefore);
    print $stringAfter;

    Output:
   `abc-def-ghi`
