PHP - 为什么包含另一个文件中的函数会失败？
我正在尝试将一个 PHP 文件中的函数包含到另一个 PHP 文件中，并使用带有参数的函数并获取返回值。一切都很好，直到我运行该函数，PHP 死掉了。我该如何解决这个问题？
timestamp_reader.php：
<?php
function get_time($timestamp){
$year = substr($timestamp, 0, 4);
$month = substr($timestamp, 4, 2);
if(substr($month, 0, 1) == "0")
$month = substr($month, 1, 1);
$day = substr($timestamp, 6, 2);
if(substr($day, 0, 1) == "0")
$day = substr($day, 1, 1);
$hour = substr($timestamp, 8, 2);
if(substr($hour, 0, 1) == "0")
$hour = substr($hour, 1, 1);
$hour = intval($hour);
if($hour > 12){
$hour = $hour - 12;
$pm = true;
}else $pm = false;
$minute = substr($timestamp, 10, 2);
if(substr($day, 0, 1) == "0")
$day = substr($day, 1, 1);
if($pm) $minute .= " PM";
else $minute .= " AM";
return $month . "/" . $day . "/" . $year . " " . $hour . ":" . $minute;
}
?>
以及我想要访问此函数的文件（注意，它位于不同的目录中）：
...some PHP code before this...
include "/project/includes/timestamp_reader.php";
while($row=mysql_fetch_array($result)){
$msg = $row['message'];
$timestamp = $row['timestamp'];
$time = get_time($timestamp);
echo "<p><center>" . $time . " " . $msg . "</center></p>";
}
我想弄清楚并将其用于各种函数，这样我就不必键入它们如果可能的话，每次都会。另外，我需要类似的东西来创建项目范围的变量。
无论如何，感谢您的任何帮助！
I am trying to include a function from one PHP file into another and use the function with a parameter and get a return value. All is good until I run the function, where PHP dies. How can I fix this?
timestamp_reader.php:
<?php
function get_time($timestamp){
$year = substr($timestamp, 0, 4);
$month = substr($timestamp, 4, 2);
if(substr($month, 0, 1) == "0")
$month = substr($month, 1, 1);
$day = substr($timestamp, 6, 2);
if(substr($day, 0, 1) == "0")
$day = substr($day, 1, 1);
$hour = substr($timestamp, 8, 2);
if(substr($hour, 0, 1) == "0")
$hour = substr($hour, 1, 1);
$hour = intval($hour);
if($hour > 12){
$hour = $hour - 12;
$pm = true;
}else $pm = false;
$minute = substr($timestamp, 10, 2);
if(substr($day, 0, 1) == "0")
$day = substr($day, 1, 1);
if($pm) $minute .= " PM";
else $minute .= " AM";
return $month . "/" . $day . "/" . $year . " " . $hour . ":" . $minute;
}
?>
And the file that I want access to this function (note, it is in a different directory):
...some PHP code before this...
include "/project/includes/timestamp_reader.php";
while($row=mysql_fetch_array($result)){
$msg = $row['message'];
$timestamp = $row['timestamp'];
$time = get_time($timestamp);
echo "<p><center>" . $time . " " . $msg . "</center></p>";
}
I'd like to figure this out and use it for a variety of functions so I don't have to type them in every time if possible. Also, I need something similar for creating project-wide variables.
Anyway, thanks for any and all help!

避免重新发明轮子怎么样？ ..尤其是畸形的一个：
How about you avoid reinventing a wheel ? .. especially so misshapen one :
为什么不在 PHP 中使用
date()函数？例如，
将根据现在的时间戳打印出 09-24-2011 - 如果时间戳是昨天的，则回显的日期将是昨天。
Why not use the
date()function within PHP?For example,
Will print out 09-24-2011 based on that time stamp for right now - if the timestamp was from yesterday, the date echo-ed will be yesterday.
尝试使用 require() ，如果路径错误，它会失败，我敢打赌就是这种情况。
try with require(), it fails if the path is wrong, which I bet is the case.
