PHP Looping content of a page, make and keep changes - php

Database generated page will be saved as static pages but the url's within the page itself needs to be rewritten. The function is already made.
-> I got an error : implode(): Invalid arguments passed
Goal : the website will be in 3 languages but they all uses the same page index.php. So that's not good enough for google. So static pages will be generated and each language will have his own folder.
While the page is extracted I'll do some url rewrite within the codes of the extracted content. (No not just an Url rewrite for .htaccess. That's not the point at all.)
The pages will change name completely and becomes a static page.
I hope this is clear enough. Hope someone find a way, I tried so much I have almost lost hope to accomplish this.
//At the beginning of the page above the HTML tag.
//Destination for the page and the new name for the page.
$cachefile = "../".trim($_GET['lang'])."/".trim($_GET['page']).".php";
ob_start();
<html>
<body>
...
</body>
</html>
// At the end of the page
$content = ob_get_contents();
// here the loop with my function to find an url
$content = ob_get_contents();
$arrcontent = explode(" ",$content);
$newcontent="";
foreach($arrcontent as $value){
$value = replaceurl_newurlmenu($value, $pathwebsite, $pathmenu);
$newcontent .= array($value);
}
$content = implode(" ",$newcontent);
// then write everything to a page at a new destination
$fp = fopen($cachefile, 'w');
fwrite($fp, $content);
fclose($fp);
ob_end_flush();

To fix what you have
$arrcontent = explode(" ",$content);
$newcontent=array();
foreach($arrcontent as $value){
$value = replaceurl_newurlmenu($value, $pathwebsite, $pathmenu);
$newcontent[] = $value;
}
$content = implode(" ",$newcontent);
But I would consider looking at array_walk method too.

Multiple Token replacement php function correctly replaces the tokens with assigned widget but drops the content containing the tokens

I have a php function that replaces tokens with assigned content. The tokens are actually paths to the widgets: {widgets/buttons/next-step.php} which the function retrieves the widget via an include();.
The function successfully retrieves and renders the widgets, but the content the token is in is lost. I have tried numerous adjustments to the code without success. I am not sure what I am doing wrong.
Content Sample:
$content = '<h1>Button</h1>{widgets/buttons/next-step.php}';
$content .= '<h1>Duscussion</h1>{widgets/discussions/altar-of-christ.php}';
$content .= '<h1>Build Altar Lab</h1>{widgets/labs/altar-of-christ-lab.php}';
All the <h1>s are dropped.
PHP Function:
function replaceTokens($content){
# minimize content
$content = str_replace("\r\n",'',str_replace("\t",'',$content));
# run content through short code/widget preg match
preg_match_all("'{(.*?)}'si", $content, $match);
# replace token with content
foreach($match[1] as $val) {
# rebuild token for str_replace()
$token = '{'.$val.'}';
# get token content
$this_content = include($val);
# replace token with content
$content = str_replace($token,$this_content,$content);
}
return $content;
}
If I change return $content; to echo $content; the function renders each widget correctly and then under the widgets it returns each of the <h1> tags with the number 1 under each headline as follows:
WIDGET 1
WIDGET 2
WIDGET 3
Button
1
Discussion
1
Build Altar Lab
1
I understand what is happening but do not know how to resolve the issue...
The function simply includes and renders the widgets as it loops through the preg_match_all and then the str_replace() does not recognize $this_content and returns a 1 instead.
I have tried:
ob_start();
eval('?>'.file_get_contents($val).'<?php;');
$this_content = ob_get_clean();
and:
$this_content =file_get_contents($val);
Thinking the function needed just the code of the widgets and contain it within $this_content to allow str_replace() to function properly but the result is the same.
Any assistance would be greatly appreciated.
ISSUE RESOLVED:
The function was rendering the execution of the php code and not passing the code itself. I simply changed the .php files to .dat files and then changed $this_content = include($val); to $this_content = file_get_contents($val); and then return $content; to echo $content;.
This allows the function to store the code itself in the $this_content variable, which in turn, allows the $content = str_replace($token,$this_content,$content); to do its job correctly.
I also improved the minimization of the $content variable at the top of the function.
The new code:
Content Code:
$content = '<h1>Button</h1>{widgets/buttons/next-step.dat}';
$content .= '<h1>Discussion</h1>{widgets/discussions/altar-of-christ.dat}';
$content .= '<h1>Build Altar Lab</h1>{widgets/labs/altar-of-christ-lab.dat}';
echo '<div class="grid"><div class="row"><div class="col_12">';
replaceTokens($content);
echo '</div></div></div>';
The Function:
function replaceTokens($content){
# minimize content
$content = str_replace("\r",'',$content);
$content = str_replace("\n",'',$content);
$content = str_replace("\t",'',$content);
# run content through short code/widget preg match
preg_match_all("'{(.*?)}'si", $content, $match);
# replace token with content
foreach($match[1] as $val) {
# rebuild token for str_replace()
$token = '{'.$val.'}';
# store widget code
$this_content = file_get_contents($val);
# replace token with content
$content = str_replace($token,$this_content,$content);
}
echo $content;
}

Warning file_get_contents in DOM Parser

My case is, I want to scrap a website, which is success, and I'm using PHP cURL. The problem start when I want to use the DOM Parser to get the content I want. Here is the warning came out:
the error image is here
And the code I use is here. Before this code, I scrap a website using cURL, it's working, but just this part got error :
include 'simple_html_dom.php';
//Here is where I scraping, no need to show it
$fp = fopen(dirname(__FILE__) . '/airpaz.html', 'w');
//$html contain the page I scrap
fwrite($fp, $html);
fclose($fp);
$html_content = file_get_contents(dirname(__FILE__) . '/airpaz.html');
echo $html_content;
$html2 = new simple_html_dom();
$html2->load_file($html_content);
Hope you guys can help, thanks
It looks like you are trying to read a file 3 times:
$read_file = fread($fr, filesize(dirname(__FILE__) . '/airpaz.html'));
and:
$html_content = file_get_contents($read_file);
and:
$html2->load_file($html_content);
In the last two instances, instead of a file-name you pass html contents to the function so that will not work.
You should read the file only once and use string functions on the contents you receive. Or you open the url directly in $html2->load_file().
try this code
include 'simple_html_dom.php';
$html_content = file_get_html(dirname(__FILE__) . '/airpaz.html');
echo $html_content;
$html2 = new simple_html_dom();
$html2->load_file($html_content);

How can I replace braces with <?php ?> in php file?

I wanna replace braces with <?php ?> in a file with php extension.
I have a class as a library and in this class I have three function like these:
function replace_left_delimeter($buffer)
{
return($this->replace_right_delimeter(str_replace("{", "<?php echo $", $buffer)));
}
function replace_right_delimeter($buffer)
{
return(str_replace("}", "; ?> ", $buffer));
}
function parser($view,$data)
{
ob_start(array($this,"replace_left_delimeter"));
include APP_DIR.DS.'view'.DS.$view.'.php';
ob_end_flush();
}
and I have a view file with php extension like this:
{tmp} tmpstr
in output I save just tmpstr and in source code in browser I get
<?php echo $tmp; ?>
tmpstr
In include file <? shown as <!--? and be comment. Why?
What you're trying to do here won't work. The replacements carried out by the output buffering callback occur after PHP code has already been parsed and executed. Introducing new PHP code tags at this stage won't cause them to be executed.
You will need to instead preprocess the PHP source file before evaluating it, e.g.
$tp = file_get_contents(APP_DIR.DS.'view'.DS.$view.'.php');
$tp = str_replace("{", "<?php echo \$", $tp);
$tp = str_replace("}", "; ?>", $tp);
eval($tp);
However, I'd strongly recommend using an existing template engine; this approach will be inefficient and limited. You might want to give Twig a shot, for instance.
do this:
function parser($view,$data)
{
$data=array("data"=>$data);
$template=file_get_contents(APP_DIR.DS.'view'.DS.$view.'.php');
$replace = array();
foreach ($data as $key => $value) {
#if $data is array...
$replace = array_merge(
$replace,array("{".$key."}"=>$value)
);
}
$template=strtr($template,$replace);
echo $template;
}
and ignore other two functions.
How does this work:
process.php:
<?php
$contents = file_get_contents('php://stdin');
$contents = preg_replace('/\{([a-zA-Z_][a-zA-Z_0-9]*)\}/', '<?php echo $\1; ?>', $contents);
echo $contents;
bash script:
process.php < my_file.php
Note that the above works by doing a one-off search and replace. You can easily modify the script if you want to do this on the fly.
Note also, that modifying PHP code from within PHP code is a bad idea. Self-modifying code can lead to hard-to-find bugs, and is often associated with malicious software. If you explain what you are trying to achieve - your purpose - you might get a better response.

php get all files from a remote directory

I have searched, and searched for 3+ hours this morning and tried over 10 different setups for how to grab and display a list of images from a url, and none of them worked correctly. I would either end up with no info displaying, or a 500 error. Can someone point me to an example or help me out here on how to do this properly. file_get_contents is not a viable option.
Example Directory: http://www.webtoonlive.com/webtoon/fantasy_world_survival/ch02/
Files i know that are in that directory:
001.jpg,
002.jpg,
003.jpg
I would like the output to be the exact url to the file.
Let me know if more info is needed, i'm not 100% sure exactly how to explain it right lol.
Edit:
ok so what I guess i actually want to do is check the url for all the image tags and display a list with the full url to that image.
New to working with this url+images+php stuff so please don't hit me too hard with your downvote hammer with no comments lol.
Code I Tried:
<?php
/*
Credits: Bit Repository
URL: http://www.bitrepository.com/
*/
$url = $location;
// Fetch page
$string = FetchPage($url);
// Regex that extracts the images (full tag)
$image_regex_src_url = '/<img[^>]*'.
'src=[\"|\'](.*)[\"|\']/Ui';
preg_match_all($image_regex, $string, $out, PREG_PATTERN_ORDER);
$img_tag_array = $out[0];
echo "<pre>"; print_r($img_tag_array); echo "</pre>";
// Regex for SRC Value
$image_regex_src_url = '/<img[^>]*'.
'src=[\"|\'](.*)[\"|\']/Ui';
preg_match_all($image_regex_src_url, $string, $out, PREG_PATTERN_ORDER);
$images_url_array = $out[1];
echo "<pre>"; print_r($images_url_array); echo "</pre>";
// Fetch Page Function
function FetchPage($path)
{
$file = fopen($path, "r");
if (!$file)
{
exit("The was a connection error!");
}
$data = '';
while (!feof($file))
{
// Extract the data from the file / url
$data .= fgets($file, 1024);
}
return $data;
}
?>
and it returned a blank page
Based loosely on the code you already tried (but was riddled with problems). This grabs the full contents of the URL $url, parses out the <img> src attributes, and then outputs them.
Because this particular web host uses <base href=""/> tag to reset the base part of all URLs on the page, I've added a $base variable which you should set to the contents of the base tag.
Additionally, it looks like this particular web host has some pretty smart anti-hotlinking in place, so not all images may be visible.
But! Give it a whirl, let me know if it does what you need it to, and any questions.
<?php
$url = 'http://www.webtoonlive.com/webtoon/fantasy_world_survival/ch02/';
$base = 'http://www.webtoonlive.com/';
// Pull in the external HTML contents
$contents = file_get_contents( $url );
// Use Regular Expressions to match all <img src="???" />
preg_match_all( '/<img[^>]*src=[\"|\'](.*)[\"|\']/Ui', $contents, $out, PREG_PATTERN_ORDER);
foreach ( $out[1] as $k=>$v ){ // Step through all SRC's
// Prepend the URL with the $base URL (if needed)
if ( strpos( $v, 'http://' ) !== true ) $v = $base . $v;
// Output a link to the URL
echo '' . $v . '<br/>';
}
Sample output:

Problem with include on my Drupal

I have a problem with 3rd-party-system integration in my drupal site.
Sorry for my english, i'm from russia, but i will try to explain my problem well.
Integration idea:
2 .php files
2 php-script lines (include
function's)
The problem is:
this scripts call to outside perl
(.pl) script. Perl script read the
parameters (parameters transfers by
url) and generate content.
I can't see this perl script, but i
know - hes working, but not in my
page :)
2 php files:
spectrum_view.php
<?php
$url = "http://young.spectrum.ru/cgi-bin/programs_view.pl";
$param = $_GET;
if (!empty($param))
{
$url .= "?";
foreach ($param as $keys=>$value)
{
$url .= "&".$keys."=".urlencode($value);
}
} echo $content = file_get_contents($url);
?>
spectrum_form.php
<?php
$url ="http://young.spectrum.ru/cgi-bin/programs_form.pl";
$params = $_GET;
if (!empty($params))
{
$url .= "?";
foreach ($params as $keys=>$value)
{
$url .= "&".$keys."=".urlencode($value);
}
} echo iconv("windows-1251","utf-8",(file_get_contents($url)));
?>
and the 2 php-lines, wich i insert in my drupal pages
(the first i insert in page http://new.velo-travel.ru/view
and the second in the right block)
include("http://new.velo-travel.ru/themes/themex/spectrum_view.php?$QUERY_STRING");
include("http://new.velo-travel.ru/themes/themex/spectrum_form.php?act=/view$QUERY_STRING");
So, i solved this problem, but not in drupal - only on my Localohost, i just create a 2 page:
form.php:
<?php
$url ="http://young.spectrum.ru/cgi-bin/programs_form.pl";
$params = $_GET;
if (!empty($params)){
$url .= "?";
foreach ($params as $keys=>$value) $url .= "&".$keys."=".urlencode($value);
}
$content = file_get_contents($url);
print $content;
**require_once 'view.php';**
?>
view.php:
<?php
$url = "http://young.spectrum.ru/cgi-bin/programs_view.pl";
$param = $_GET;
if (!empty($param))
{
$url .= "?";
foreach ($param as $keys=>$value)
{
$url .= "&".$keys."=".urlencode($value);
}
}
$content = file_get_contents($url);
print $content;
?>
=(
I'm not entirely sure, as to what you are trying to do. But it seems like you want to generate this content from the perl script. If this is a special page with it's own template, you should move all this code into template.php. This file is made to hold some logic you want to create the content for your page.
Personally I would prefer to make a module to handle all this, but it's probably easier to do this in the theme, with what you got now. It seems like you are making a form, and some content based on the form. This could be done in a module. You could create a Drupal form, and then handle the validation with drupal, and jst submit the data to perl. But if you would want to get it from perl, going with the theme is probably best. So how do you do it?
Implement a preprocess function for the tpl.php file you use.
Create all the logic here, you could copy the php files you use over or just include them. Import, assign the result to a variable the will be accessible in the template file.
Print the variable in your template.
In code this would look something like this:
//template.php file
function mytheme_preprocess_somename(&$vars) {
include('php');
// Do some logic.
$vars['form'] = $result_a;
$vars['my_content'] = $result_b;
}
// your .tpl.php
// Some markup here
<div><?php print $my_content; ?></div>
<div><?php print $form; ?></div>
Now, I'm not sure exactly what you are after, but something like this should help you along. Note it's important what you call your variables inside the template file, as you can overwrite some Drupal variables like $content, which can cause some bugs.
You probably are running into a security issue. Please note allow_url_fopen and allow_url_include - these settings must have accordant settings in your php.ini. Otherwise you can't e.g. include a remote file for security reasons.
