PHP包含基於URL參數

Question

我有一個目錄，其中包含30個PHP包含各種HTML塊。我試圖根據url的參數包含這些文件的5-6個。該文件被命名爲這樣的：

1.PHP 2.PHP 3.php ... 30.php

和URL看起來像這樣：

www.example.com ？包括= 1-4-14-20-29

我需要這樣的東西，但我知道這是無效的：

$include = @$_GET['include']; // hyphen separated list of file names. 

$arr = explode("-", $include); //explode into an array 
foreach ($arr as $filename) { 
include $filename."php"; 

}

結果我想獲得：

<php 
include '1.php'; 
include '4.php'; 
include '14.php'; 
include '20.php'; 
include '29.php'; 
?> 

感謝您可以提供任何幫助。

Answer 1

我會遍歷數組，所以纔會取最小值和最大值，像這樣：

<?php 
$include = $_GET['include']; // hyphen separated list of file names. 

$arr = explode("-", $include); //explode into an array 

# What's the min and max of the array? 
$max = max($arr); 
$min = min($arr); 

# Just to see what's happening. 
echo $max."-".$min; 

# Start at the lowest value, and work towards the highest in the array. 
for ($i = $min; $i <= $max; $i++) { 

# Include the nth php file 
include $i.".php"; 
} 

?>

噢，對不起，剛纔看到我誤解你的問題，你不是在尋找範圍，而是在尋找個人電話。那麼這一個是你的：

<?php 
$include = $_GET['include']; // hyphen separated list of file names. 

$arr = explode("-", $include); //explode into an array 
foreach ($arr as $filename) { 
include $filename.".php"; 
} 

?>
