這個判斷要怎麼簡寫才好？

Answer 1

用Switch switch ($nowSelf) { case '/x.php': $real_title = $x; break; case '/x.php': $real_title = $x; break; default: # code... break; }

Answer 2

$arr = new Array( 'default' => $default_title '/x.php' => $x, ... => .. ); // 很久没写 PHP 了，不知道如果 key 不存在是会报错还是怎样 // 或者你也可以用 for 循环找到匹配的 $title，否则使用默认 $arr['default'] $title = $arr[$nowSelf];

Answer 3

$arr = [ '/x.php' => 'x', '/y.php' => 'y', '/z.php' => 'z', ] $title = !isset($arr[$nowSelf])?'':$arr[$nowSelf];

Answer 4

个人推荐使用 switch switch (variable) { case 'value': # code... break; default: # code... break; }

Answer 5

$arr = [ '/x.php' => 'x', '/y.php' => 'y', '/z.php' => 'z', ]; $real_title = $arr[$nowSelf] ?? 'Your default value';
