fatal error: cannot redeclare这种php问题,开发可能会碰到过,原因是很简单的,就是重复调用了相同名字的函数,看如下的实例:

<?php
function mydate($format = &#39;y-m-d h:i:s&#39;, $timest = 0) {
    global $cfg_cli_time;
    $addtime = $cfg_cli_time * 3600;
    if (emptyempty($format)) {
        $format = &#39;y-m-d h:i:s&#39;;
    }
    return gmdate($format, $timest + $addtime);
}
?>
Copy after login

我们来进行包含:

require_once(dedeinc."/inc/inc_fun_funstring.php");
Copy after login

下面的代码也包含了一个名为mydate的函数,如果现在我们这样用就出现如 a.php

<?php
require_once (dedeinc . "/inc/inc_fun_funstring.php");
function mydate($format = &#39;y-m-d h:i:s&#39;, $timest = 0) {
    global $cfg_cli_time;
    $addtime = $cfg_cli_time * 3600;
    if (emptyempty($format)) {
        $format = &#39;y-m-d h:i:s&#39;;
    }
    return gmdate($format, $timest + $addtime);
}
?>
Copy after login

就会出现fatal error: cannot redeclare mydate() (previously declared in
