List and link php files in a folder and its metatag description

droopsnoot · May 30, 2021, 5:43pm

But, when you access the php code via the filesystem, and not via the server, the include files are not processed because it is only reading your PHP source code, not executing it.

You can call the metatags script on a remote server; you can’t GLOB a remote server.

Today I will try to add links to the names of files. Thank you.

web148 · June 1, 2021, 1:41pm

John, today I managed to link the listed files, but the result is quite ugly.
This is the modified code

//======================================
function getDescription( string $file)
: string 
{
$result = ''; // eEMPTY IF FALSE

$contents = file_get_contents($file);
$iStart   = strpos( $contents , "\$description");
if( $iStart ) 
{
 $tmp    = substr($contents, ++$iStart) ;
 $tmp2   = strpos($tmp, ';');

 $result = '<ul>'
         . '<li><b><a href="'.$file.'">$file</a></b>: ' //$file 
         .   substr($contents, $iStart, $tmp2)
         .'</li></ul>'
         ;
}// endif;

return $result;
}//

How could I get only the *name of the file (without extension) : *description (without word “description” before).
Thanks a lot for your excellent work.

John_Betong · June 1, 2021, 2:06pm

Try this:

https://www.php.net/manual/en/function.strrchr.php

Search for “/“, get the position and use substr(…)

This is only one solution, I should imagine there are many more.

Edit

To remove the .PHP file extension try str_replace(…) or I think strstr(…)

web148 · June 2, 2021, 6:45pm

Thank you. Today I managed to list and link the php files with only its name. But there is still a description= which I’d rather avoid.

The code I used (just the modified part)

function getDescription( string $file)
: string 
{
  $result = ''; // eEMPTY IF FALSE

  $contents = file_get_contents($file);
  $iStart   = strpos( $contents , "\$description");
  if( $iStart ) 
  {
    $tmp    = substr($contents, ++$iStart) ;
    $tmp2   = strpos($tmp, ';');

    $result = '<ul>'
            . '<li><b><a href="'.$file.'">'
            .   substr("$file",2,-4)
            . '</a></b>: ' //$file 
            .   substr($contents, $iStart, $tmp2)
            .'</li></ul>'
            ;
  }// endif;

  return $result;
}//

John_Betong · June 3, 2021, 3:23am

If you just want the text removed after description = then try the following function:

<?php 
declare(strict_types=1); // this file wide type checking
error_reporting(-1); // display maximum errors
ini_set('display_errors', 'true'); // show errors on screen


$aDescriptions = [
  'description="come estrarre exif da immagini con php" ',
  'description = $aTags("description"] ?? FALSE',
  'description="ricavare metatags"',
];

foreach($aDescriptions as $key => $desc) :
  echo '<br>ORIGINAL ==> ' . $desc;
  echo '<br>FILTERED ==> ' . getRidOfEqualSign($desc);
  echo '<br>';
endforeach;


//========================================
function getRidOfEqualSign( string $tmp)
: string 
{
  $result = ''; // EMPTY IF FALSE

  $iPos = strpos($tmp, '=');

  $result = substr($tmp, ++$iPos); // notice the preceeding ++ 

  return $result;
}//

Please note that PHP has numerous functions that are very helpful and it is worth glancing at all the functions details for future reference,

web148 · June 3, 2021, 8:49am

No, I just want to remove the word “description =”. More simply

John_Betong · June 3, 2021, 9:35am

Try the following:

if( $iStart ) 
  {
    $tmp    = substr($contents, ++$iStart) ;
    $tmp2   = strpos($tmp, ';');
    $tmp3 = substr($contents, $iStart, $tmp2) ;
    $tmp3 = getRidOfEqualSign($tmp3); // make sure the function is available

    $result = '<ul>'
            . '<li><b><a href="'.$file.'">'
            .   substr("$file",2,-4)
            . '</a></b>: ' //$file 
            .    $tmp3
            .'</li></ul>'
            ;
  }// endif;

Not tried because I’m very late for lunch

web148 · June 8, 2021, 6:45am

Excuse me for this my late answer, but your last code unfortunately doesn’t work (even changing the second $tmp3 to $tmp4) …

web148 · June 13, 2021, 4:29pm

Good! Today I managed to use your code (with some modifications) to get a list of files with their description.
There would be some further improvements, if you want and I don’t ask too much .
That is: 1) avoid to list index.php (necessary), 2) add, besides description metatag, also title and author metatag (possible?).

John_Betong · June 15, 2021, 2:20am

Please post your modifications.

1) avoid to list index.php (necessary)

Check the script because it looks as though checks are already in place:

$sLowercase = strtolower($file) ;
    if('index.php'===$sLowercase)
    {
      echo '<h2> Do not use: '  .$file .'</h2>' ;
    }else{

2) add, besides description metatag, also title and author metatag (possible?).

I think you would need to add two more checks for title and author instead of just description.

  // Prevent index not found error
        $description = $aTags['description'] ?? FALSE ;
        if($description) 
        {
          $result .=  '<dl>';
         #$result .=  '<dt> <b> FILE [meta]: </b> ' .$key .'</dt>';
          $result .=   '<dd> &lt;meta&gt; description = "' .$description .'"&gt; </dd>';
          $result .=  '</dl>';
        }//endif($description) 
        $hasDescription = getDescription($file);
        if( strlen( $hasDescription ) )
        {
          $result .= $hasDescription;
        }

John_Betong · July 1, 2021, 5:17am

The original question was to find the value of METATAGS and not find PHP variables. If the latter is now the requirement then please raise another Topic.

Please also ensure that the $PATH variable includes files with either a .php and/or .html extension.

Also try this modification which I have tested and it works fine:

It looks as though i was not clear

I was like the header contents of the file which the script I supplied is not finding the METATAG “authors”.

I suppose you mean metatag “author” (not “authors”), witch is however a common metatag
But the most important: what do you mean by “header content”?
The file containing the above script is one of the files whose metatags should be shown.

List and link php files in a folder and its metatag description

Edit

1) avoid to list index.php (necessary)

2) add, besides description metatag, also title and author metatag (possible?).
