Question

我正在呼叫api并用我自己的URL替换远程URL。 http://example.com/a/b/icon_name.gif到http://example.org/c/d/icon_name.png。域名将被替换，文件扩展名将从.gif替换为.png。更换两个部分字符串比使用两个函数更经济的方法是什么？

$hourlyUrl = array_map(
    function($str) {
        return str_replace('example.com/a/b/', 'example.org/c/d/', $str);
    },
$hourlyUrl
);

$hourlyUrl = array_map(
    function($str) {
        return str_replace('.gif', '.png', $str);
    },
$hourlyUrl
);

Answer 1

// Provides: You should eat pizza, beer, and ice cream every day
$phrase  = "You should eat fruits, vegetables, and fiber every day.";
$healthy = array("fruits", "vegetables", "fiber");
$yummy   = array("pizza", "beer", "ice cream");

$newphrase = str_replace($healthy, $yummy, $phrase);

您的案例

$old_url = "http://example.com/a/b/icon_name.gif";
$old = array("example.com/a/b/", ".gif");
$new = array("example.org/c/d/", ".png");

$new_url = str_replace($old, $new, $old_url);

// Output: http://example.com/c/d/icon_name.png

在php中只替换字符串的一部分
