问题回答

如果您只是想删除方括号,请您使用http://php.net/manual/en/Function.trim.php” rel=“nofollow noreferer”>trim(功能。

    $str = "{1}";
    $str = trim($str, "{}");
    echo $str;  //output: 1

EDIT:我删除了 com号——“{}”足够了,因为基点之前的三(a)项参数(即“i,}”)

您可以使用一种预选功能,定期表达。

你需要做些什么。

如果你想获得舱面的某种特性,$str ={1};str ***将退回舱面的第二种特性。

取决于你的实际情况。

$number = $string{1};

但是,我猜想你们需要更多的东西。

preg_match( /{([0-9]+)}/ , $string, $matches);
$number = $matches[1];
