用掩码替换字符串模式的最快方法

我有类似的字符串

$string = "string_key::%foo%:%bar%";

和参数数组

$params = array("foo" => 1, "bar" => 2);

如何以 $string 模式替换此参数？ 预期结果是

string_key::1:2

首先，您需要重写$params array:

$string = "string_key::%foo%:%bar%";
$params = array("foo" => 1, "bar" => 2);
foreach($params as $key => $value) {
    $search[] = "%" . $key . "%";
    $replace[] = $value;
}

之后，您可以简单地将数组传递给str_replace():

$output = str_replace($search, $replace, $string);
