echo
is a function, which prints its argument. echo
是一个函数,用于打印其参数。 You can actually call echo
like this: echo("hello");
你可以像这样调用
echo
: echo("hello");
, which is syntactically identical to echo "hello";
,在语法上与
echo "hello";
相同echo "hello";
if you are calling echo
, you are already in php mode (ie: there's an open <?php
somewhere before your echo
call), so there's no need to enter php mode again for the get_bloginfo
call. 如果你正在调用
echo
,你已经处于php模式(即:在你的echo
调用之前有一个开放的<?php
),所以不需要为get_bloginfo
调用再次进入php模式。 get_bloginfo
returns a string, so you can just concatenate its output with the rest of your echo
parameter. get_bloginfo
返回一个字符串,因此您可以将其输出与echo
参数的其余部分连接起来。
