Automatic Blog - Multiple PHP function declaration? - php

Question

I want to generate HTML using PHP based on files in a specific Folder, everything works for the first File but if I add a second File, I just see:
Fatal error: Cannot redeclare getTitle() (previously declared in [path]:3) in [path].php on line 4
I understood the Problem but I don't know how to solve it. This is the PHP-Code of the main File:
foreach (glob("content/blog/*.php") as $file) {
require_once $file;
$index = str_replace("content/blog/", "", str_replace(".php", "", str_replace("img/", "", $file)));
?>
<div class="content">
<h3><?php getTitle() ?><span><?php getPublishedDate() ?></span></h3>
<p><?php getContent() ?></p>
</div>
<?php
$file = null;
}
?>
And this is the PHP-Code in every Blog-File:
<?php
function getTitle() {
echo "Lorem Ipsum 2!";
}
function getPublishedDate() {
echo "When Time has finally come";
}
function getContent() {
echo "<p>Text</p>";
}
?>
I searched for opposites of include, include_once, require or require_once. I also tried Setting the variable back to null before foreach is called again.
Thanks for any help in advance.

Define a class to store the information about one blog post.
// name this file class.blogEntry.php
class blogEntry {
var $title;
var $publishedDate;
var $content;
public function getTitle() {
return $this->title;
}
public function setTitle($title) {
$this->title = $title;
}
public function getPublishedDate() {
return $this->publishedDate;
}
public function setPublishedDate($date) {
$this->publishedDate = $date;
}
public function getContent() {
return $this->content;
}
public function setContent($content) {
$this->content = $content;
}
}
For each blog post create a simple php file to set it's different properties
$entry->setTitle("Lorem Ipsum 2!");
$entry->setPublishedDate("When Time has finally come");
$entry->setContent("<p>Text</p>");
Modify your output to use the class and the class based blog entries
require_once 'class.blogEntry.php';
foreach (glob("content/blog/*.php") as $file) {
$entry = new blogEntry();
require_once $file;
$index = str_replace("content/blog/", "", str_replace(".php", "", str_replace("img/", "", $file)));
?>
<div class="content">
<h3><?php $entry->getTitle() ?><span><?php $entry->getPublishedDate() ?></span></h3>
<p><?php $entry->getContent() ?></p>
</div>
<?php
$file = null;
}
?>

The problem is you have several files, defining the same function getTitle and you are requiring them.
Requiring or including a *.php file is like merging all the code into one single file, which explains the error, because you are requiring n files and in each of them you are defining the same functions.
You can do something like this instead of functions you can use associative array.
<?php
// blog_file_1.php
$prop = array(
'title' => "This is file 1!",
'published_date' => "When Time has finally come",
'content' => "<p>Text</p>"
);
<?php
// blog_file_2.php
$prop = array(
'title' => "This is file 2!",
'published_date' => "When Time has finally come",
'content' => "<p>Text</p>"
);
<?php
// blog.php
foreach (glob("content/blog/*.php") as $file) {
require_once $file;
$index = str_replace("content/blog/", "", str_replace(".php", "", str_replace("img/", "", $file)));
?>
<div class="content">
<h3><?php echo $prop['title'] ?><span><?php echo $prop['published_date'] ?></span></h3>
<p><?php echo $prop['content'] ?></p>
</div>
<?php
$file = null;
}
?>

I'm not sure if this will help you but maybe it will help others that might find this question as it hits what I was looking for. I was looking to exactly this a few days ago and didn't find much for a simple PHP script to generate a blog. I put this together after searching Stack for different functions (Generate gallery with links from a folder, PHP Pagination, Passing Variable from Another PHP File, Sort Files) and put this together.
Code for the main blog page
\\Blog.php
<?php
$directory = "blog/folder/";
$blogfiles = glob($directory . "*.php");
usort($blogfiles, function($file_1, $file_2)
{
$file_1 = filectime($file_1);
$file_2 = filectime($file_2);
if($file_1 == $file_2)
{
return 0;
}
return $file_2 < $file_1 ? 1 : -1;
});
$post_count = 5;
$total_pages = ceil(count($blogfiles)/$post_count);
$page = $_REQUEST['page']; ///make it dyanamic :: page num
$offset = ($page-1)*$post_count;
$files_filter = array_slice($blogfiles, $offset,$post_count);
foreach ($files_filter as $blogfile) {
ob_start();
include "$blogfile";
ob_end_clean();
echo '<div class="blog-post"><a href="'.$blogfile.'"><img src="'.$BLOG_IMG.'"><h1
class="blog-title">' . $BLOG_TITLE . '</h1></a><br><p class="blog-summary">' .
$SUMMARY . '</p></div><hr>', "\n";
}
if($total_pages > 1){
if($page > 1){
echo '<div class="blog-pagination prev-page"><a href="blog.php?page='.($page-
1).'">Prev Page</a></div>';
}
if($page != $total_pages){
echo '<div class="blog-pagination next-page"><a href="blog.php?page='.
($page+1).'">Next Page</a><div class="blog-pagination">';
}
}
?>
Here is a blog post template
\\post1.php
<?php
$DOC_TITLE = "Document Title for browser tab";
$BLOG_TITLE = "Blog Post Title";
$SUMMARY = "Page summary";
$BLOG_IMG = "/Path/to/blog/image.jpg";
require $_SERVER['DOCUMENT_ROOT'] . '/header.php'; //Pre-made HTML header in the root folder - or just replace with HTML header
?>
\\content
<?php
require $_SERVER['DOCUMENT_ROOT'] . '/footer.php'; //Pre-made HTML footer in the root folder - or just replace with HTML footer
?>
