## Convert from PHP to ASP extensions with SSI includes ##
 
getFiles() - Get all php files from root / includes directory
stripIncludes() - Regex php syntax and includes for SSI
saveFile(filename) - Save string to (.asp) file extension while preserving the filename
 
## Concept - 
1) function getFiles( directory ) - all php files from directory and loop through each
2) function parseDir( directory ) - copy file to .asp extension and remove the .php version
- replace php includes with SSI then save file
 
	## Examples:
	//parse includes folder '/inc' or use $_SERVER['DOCUMENT_ROOT']
	parseDir( dirname( __FILE__ ) . '/inc/' );
 
	//parse root
	parseDir( dirname( __FILE__ ) );
 
*/
	//copy all of your php source into another directory, replace 'asp_directory' and set to your export path
	parseDir( $_SERVER['DOCUMENT_ROOT'] . '/asp_directory/' );
	parseDir( $_SERVER['DOCUMENT_ROOT'] . '/asp_directory/inc/' );
 
	function getFiles($dir){
		//start with root files
		if ($handle = opendir($dir)) {
			$files = '';
			//loop through all of the files		
			while (false !== ($file = readdir($handle))) {
				if($file!='.'&&$file!='..'&&stripos($file,'.php')){ //all php files
					$files[]=$file;
				}
			}
 
			closedir($handle);
		}
		return $files;	
	}
 
	function parseDir($dir){
 
	foreach( getFiles( $dir ) as $file ){
 
	if( $file != 'convert.php' && $file != '' ){ //parse all files except this one
 
		$fname = str_replace('.php','.asp',$file);//strip off extension to add in fwrite
		$fpath = $dir . $fname;//new filename and path
		$orig = $dir . $file;
 
		//copy from php to asp extension
		if( copy($orig, $fpath) ) {
			unlink($orig);//remove the php version
		}else{
			print "Error: unable to copy file " . $orig . " - to - " . $fpath . " <br>check file permissions";
		}
 
		//remove the old php version
 
		//read the file contents into a string for replacements
		$file_str = file_get_contents( $fpath );
 
		//replace the php include statements with SSI virtual includes
		$file_str = str_replace( "<? include('", '<!--#include virtual="', $file_str ); // 'virtual' = relative path
		$file_str = str_replace( ".php'); ?>", '.asp"-->', $file_str ); //closing SSI tags
		$file_str = str_replace( ".php", ".asp", $file_str ); //replace all .php link references to .asp
 
		//if the file is writeable then proceed
		if( is_writeable( $fpath ) ){
 
			//write the new string to the .asp file - just as it should be (plain text)
			$fp = fopen( $fpath, 'w' );
			fwrite( $fp, $file_str ); //write the new file
			fclose($fp);//close
 
		}else{
			print 'Error: Cannot write to directory, check permissions on' . $fpath;
			exit;
		}//end if
 
	}//end if file
		print "parsed: " . $fpath . "<br />";
	}//end foreach
 
	}//end parseDir
