note 102005 added to function.md5

Anyone can help me to understand what these lines do: $NewU = strtolower( substr( md5( time( ) ), 0, 5 ) ); $NewP = strtolower( substr( md5( time( ) ), 5, 5 ) ); $AHcode = substr( base64_encode( md5( $NewU ) ), 5, 15 ).substr( base64_encode( md5( $NewP ) ), 10, 15 ); $afile = file_get_contents( dataPath."inc/config.php" ); $afile = str_replace( array( "\r\n", "\r", "\n" ), "{XXXBRXXX}", $afile ); $afile = preg_replace( "/\\/\\*ahash start\\*\\/(.*?)\\/\\*ahash end\\*\\//e", "", $afile ); $afile = str_replace( "{XXXBRXXX}", "\n", $afile ); $afile = str_replace( "define(\"_START_ID\"", "/*ahash start*/\ndefine(\"ahash\",\"".$AHcode."\");\n/*ahash end*/\n\ndefine(\"_START_ID\"", $afile ); thanks... ---- Server IP: 69.147.83.197 Probable Submitter: 188.158.6.90 ---- Manual Page -- http://www.php.net/manual/en/function.md5.php Edit -- https://master.php.net/note/edit/102005 Del: integrated -- https://master.php.net/note/delete/102005/integrated Del: useless -- https://master.php.net/note/delete/102005/useless Del: bad code -- https://master.php.net/note/delete/102005/bad+code Del: spam -- https://master.php.net/note/delete/102005/spam Del: non-english -- https://master.php.net/note/delete/102005/non-english Del: in docs -- https://master.php.net/note/delete/102005/in+docs Del: other reasons-- https://master.php.net/note/delete/102005 Reject -- https://master.php.net/note/reject/102005 Search -- https://master.php.net/manage/user-notes.php
