问题描述
我有一个名为 kal_test.php
的php文件,它给变量 $ vbl
一个值。在名为 kal_generator.php
的文件中需要此变量,该文件从该变量生成一个表(我将为您提供详细信息)。它是这样的:
I have a php-file called kal_test.php
which gives a value to the variable $vbl
. This variable is needed in the file called kal_generator.php
which produces a table from that variable (I'll spare you the details). It goes like this:
[kal_test.php]
[kal_test.php]
<?php
$vbl = "14/09/2011";
include ("kal_generator.php");
?>
[kal_test.php]
[kal_test.php]
<?php
// Long code converts the $vbl into a 2-dimensional array called $output
// I'll spare you the details (it works fine by the way)
?>
<table>
<tr><th>bla</th><th>blabla</th></tr>
<?php
foreach ($output as $v1) {
echo "<tr>";
foreach ($v1 as $v2) {
echo "<td>$v2</td>";
}
echo "</tr>\n";
}
?>
</table>
此设置工作正常,但我可以'使其中两个出现在同一页面上,如下所示:
This set-up works fine but I can't make two of those appear on the same page, like this:
[kal_test.php]
[kal_test.php]
<?php
$vbl = "14/09/2011";
include ("kal_generator.php");
$vbl = "21/09/2011";
include ("kal_generator.php");
?>
这将得到以下结果:
//here comes the header
<table> // table created with $vbl = "14/09/2011"
<tr><th>bla</th><th>blabla</th></tr>
<tr><td>this</td><td>works</td></tr>
<tr><td>this</td><td>works</td></tr>
</table>
//here should the second table be and also the rest of the page (footer), this is completely missing
我做错了什么?
谢谢!
What am I doing wrong?Thanks!
推荐答案
您可能在 kal_generator.php中定义了一个函数或类
。当您尝试重新定义此类函数或类时,PHP将中止。考虑将你的代码放在一个函数中,包含该函数一次然后运行函数而不是包含一个文件。
You're likely defining a function or class in kal_generator.php
. PHP aborts when you try to redefine such a function or class. Consider putting your code in a function, include that function once and then run the function instead of including a file.
<?php
require_once 'kal_generator.php';
kal_generator("14/09/2011");
kal_generator("21/09/2011");
?>
kal_generator.php
kal_generator.php
<?php
function kal_generator($vbl) {
/**
* Here, you should be creating $output
*/
echo <<EOF
<table>
<tr><th>bla</th><th>blabla</th></tr>
EOF;
foreach ($output as $v1) {
echo "<tr>";
foreach ($v1 as $v2) {
echo "<td>$v2</td>";
}
echo "</tr>\n";
}
echo "</table>\n";
}
?>
