Here it is:

Code:

#!/usr/bin/env ksh

cd /home/username/public_html/tests/
find . -name "*.php" | while read file
do
    echo "munging: $file"             # nice to see progress as it works
    mv "$file" "$file-"      # back it up
    awk '     # read the file and delete the block of php code
    /<?php/ { drop = idx = 0; snarf = 1; }  # start of a block; start buffering

    /?>/ {                  # end of a block
        if( ! drop )        # magic string not found -- show this block
        {
            for( i = 0; i < idx; i++ )
                printf( "%s\n", buffer[i] );
            printf( "%s\n", $0 );
        }

        snarf = 0;          # turn off buffering
        next;
    }

    ### change the string between the slants to be something unique to the block you wish to delete. 
    /PHP_STRING/ { drop = 1; }    # magic string found, drop if we're in a php block

    snarf {                 # if buffering, hold the record until end of block reached.
        buffer[idx++] = $0;
        next;
    }

    { print; }              # not buffering, just print the record.
    '  "$file-" >"$file"
    if (( $? > 0 ))            # handle failure by putting the file back in place
    then
        echo "edit of $file failed" >&2
        mv "$file-" "$file"             # restore original
    else
        rm "$file-"               # worked, delete backup 
    fi
done

Shouldnt the first line be:

#!/bin/ksh

LEARN ABOUT PHP

fgetss

FGETSS(3)								 1								 FGETSS(3)

fgetss - Gets line from file pointer and strip HTML tags

SYNOPSIS

       string fgetss (resource	$handle, [int  $length], [string  $allowable_tags])

DESCRIPTION

	Identical to fgets(3), except that fgetss(3) attempts to strip any NUL bytes, HTML and PHP tags from the text it reads.

PARAMETERS

	      o $handle
		-The  file  pointer must be valid, and must point to a file successfully opened by fopen(3) or fsockopen(3) (and not yet closed by
		fclose(3)).

	      o $length
		- Length of the data to be retrieved.

	      o $allowable_tags
		- You can use the optional third parameter to specify tags which should not be stripped.

RETURN VALUES

	Returns a string of up to $length - 1 bytes read from the file pointed to by $handle, with all HTML and PHP code stripped.

	If an error occurs, returns FALSE.

       Example #1

	      Reading a PHP file line-by-line

	      <?php
	      $str = <<<EOD
	      <html><body>
	       <p>Welcome! Today is the <?php echo(date('jS')); ?> of <?= date('F'); ?>.</p>
	      </body></html>
	      Text outside of the HTML block.
	      EOD;
	      file_put_contents('sample.php', $str);

	      $handle = @fopen("sample.php", "r");
	      if ($handle) {
		  while (!feof($handle)) {
		      $buffer = fgetss($handle, 4096);
		      echo $buffer;
		  }
		  fclose($handle);
	      }
	      ?>

	      The above example will output something similar to:

	      Welcome! Today is the  of .

	      Text outside of the HTML block.

NOTES

       Note

	      If PHP is not properly recognizing the line endings when reading files either on or created by a Macintosh  computer,  enabling  the
	      auto_detect_line_endings run-time configuration option may help resolve the problem.
