php中echo和return之间的区别?

问题描述:

这让我感到困惑,函数中的echo和return之间有什么区别

This so confusing me ,What is the difference between the echo and return, in functions

echo将内容输出到控制台或Web浏览器.

echo outputs content to the console or the web browser.

示例:

echo "Hey, this is now showing up on your screen!";


return在函数或方法的末尾返回一个值.


return returns a value at the end of a function or method.

示例:

function my_function()
{
    return "Always returns this";
}

echo my_function(); // displays "Always returns this"
