有没有办法重载php的_（）gettext运算符

Question

我有一个PHP应用程序，包含大量行和gettext调用，例如_("some text")

有没有办法重载这个_（“”）运算符来执行一些运行时检查？类似的东西：

function _($argument) {

    $result = _($argument); // this would be the non-overloaded _()

    /* perform some checks or logging */

    return $result;
}

Answer 1

命名空间：

namespace myUnderscore;

function _($argument) {
    $result = \_($argument); // this would be the non-overloaded _()
    /* perform some checks or logging */
    return strrev($result);
}

$argument = 'gazebo';
echo _($argument) . PHP_EOL; // call overloaded _()

echo \_($argument) . PHP_EOL; // call non-overloaded _()
