Reading files within a directory

[artie]

I'm testing a script (locally) that reads all the files in a particular directory with the file extension of 'htm' and ignores all other files/subirectories.

Here's the script:

<?php
  $path="c:/Program Files/Apache Group/Apache/htdocs/biz_dir";

$dhandle=opendir($path);
$num=1;
while  ($file = readdir($dhandle))
{       if (($file!=".") && ($file!="..") && (!is_dir($file))) ///Check for regular file
        {

   $f_size = filesize($file);
            $f_handle = fopen($file, "r");
            $f_data = fread($f_handle, $f_size);
            $file_name[$num]=$file;
            $file_ext = substr($file, strlen($file)-3, 3);
     }
              if ($file_ext == "htm")
              { 
                    echo $num;
                     echo $file_name[$num].' ';
                     $num++;
              }


}
     echo 'THE END ';
?>

Here's the output:

1animal.htm 2auto.htm 3beauty.htm 4church.htm 5clubs.htm 6construction.htm 7dining.htm 8farm.htm 9finance.htm 10gov.htm 11grocers.htm 12hotel.htm 13housing.htm 14insurance.htm 15legal.htm 16libraries.htm 17manufacturing.htm 18medical.htm 19recreation.htm 20schools.htm
21utilities.htm 22 23 24services.htm 25shopping.htm THE END

Here's the problem:

There are only 23 (htm) files in my directory.
The file 'services.htm' should be number 21
The file 'shopping.htm' should be number 22
The file 'utilities.htm' should be number 23

I can't see why the script would produce this erroneous outout. Can you?

Hallo,

the array holds more than 23 files Use a for loop to show the filenames with a number (count your files with htm extension)

You are correct...their are several other files that are not 'htm files. But the code (below) should only be counting the htm files. I don't understand....is there something that I'm not seeing?

if ($file_ext == "htm") 
                  {  

                        echo $num; 
                         echo $file_name[$num].' '; 
                         $num++; 
                  }

use it like this:

<?php
$path="c:/Program Files/Apache Group/Apache/htdocs/biz_dir";
$dhandle=opendir($path);
$num=1;
while ($file = readdir($dhandle)) {
if (($file!=".") && ($file!="..") && (!is_dir($file))) { ///Check for regular file
$file_ext = substr($file, strlen($file)-3, 3);
if ($file_ext == "php") {
echo $num;
echo $file.'<br>';
$num++;
}
}
}
echo 'THE END ';
?>

Thanks olaf, with your help I was able to get my desired results.
I removed the code below. (which is actually needed eslewhere)

 $f_size = filesize($file); 
$f_handle = fopen($file, "r"); 
$f_data = fread($f_handle, $f_size); 
$file_name[$num]=$file; 

And place it within a different IF statement:

<?php 
$path="c:/Program Files/Apache Group/Apache/htdocs/biz_dir"; 

$dhandle=opendir($path); 
$num=1; 
while  ($file = readdir($dhandle)) 
{       if (($file!=".") && ($file!="..") && (!is_dir($file))) //Check for regular file 
        {        

                $file_ext = substr($file, strlen($file)-3, 3); 
         } 
                  if ($file_ext == "htm") 
                  {
                      $f_size = filesize($file); 
                       $f_handle = fopen($file, "r"); 
                       $f_data = fread($f_handle, $f_size); 
                       $file_name[$num]=$file;  

                        echo $num; 
                         echo $file_name[$num].' '; 
                         $num++; 
                  } 


} 
     echo 'THE END '; 
?>
