[Resolved] fwrite and php coding

[Kudose]

Hey all. Dumb question time.

I am pulling my content from a source page within my server using fread. I call it $read.

Now. I have $read and I want to add to it. Keep in mind $read is in all HTML due to $read reading from a URL. What I want to add is PHP. Let's say hypothetically a counter in PHP.

I am aware of how to use fwrite, so a breif example of how I could do this would be more helpful than telling me look at fwrite in the manual.

How would I get my counter into a variable that can be added to my HTML $read content and have the code read the HTML and then execute the PHP?

Note: The page is already called .php

Thanks!

Hi,

either put the counter code into a file and read the contents with file_get_contents or put the code into a variable as string.

Then add the code to the HTML code by just concatenating it at the end of the HTML code ($html.$counter) or use preg_replace to put it somewhere inside the HTML code.

After that use eval on the string you get to execute the code.

One question:

The code you read with fread is located on a remote server, isn't it ?

Hi, maybe posting my code will help out a little. The code I am pulling with fread is actually on my server, just read as a URL instead. Some variables are left out, but you should get the idea.

$file_url = "$site_url/view_product.php?product=$product";
//get our new page's content
$file = fopen($file_url, "r");
		if (!function_exists('file_get_contents')) {
    	 $read = fread($file, 800000);
			} else {
		 $read = file_get_contents($file_url);
			}
			$read = str_replace("src=images/", "src=".$site_url."/images/", $read);
			$handle = $site_dir."/products/".$page_name;	
//if the file doesnt already exsist, create it
		if(!file_exists($handle)){	
		if (!$open = fopen($handle, "a")) { echo "Cannot open file"; }
		if(!chmod($handle, 0755)){ echo "Cannot change permission on file."; }	
		if (!fwrite($open, $read)) { echo "Cannot write to file ".$handle."<br>"; }
			} else { 
		echo "<center>File already exists.</center>"; exit; 
			}

Now, let's say I have this page called stuff.php now because of the above code. Now, what I want to do is add the below code to the end of my final $read variable, which is in all HTML but is a .php page.

$count = 0;
for($i=0;$i!=5;$i++){
$count++;
}
echo $count;

Now, what do you suggest as the best way to add my counter to the end of my last $read variable and have it work. Keeping it all in the same source page.

Thanks 🙂

Hi,

do something like this:

$read .= <<<EOCODE

<?PHP
\\$count = 0; 
for(\\$i=0;\\$i!=5;\\$i++){ 
\\$count++; 
} 
echo \\$count;
?>

EOCODE;

Make sure that there are no whitespaces at the end of the lines
$read .= <<<EOCODE and EOCODE;

Edit: put backslashes in front of every $, PHPBuilder messes up the code a little bit.

That didnt work. But I figured it out anyways.

It is just $read .= "<?php code ?>";
