<?php function bin2text( $bin_str ) { $text_str = '' ; $chars = explode ( "\n" , chunk_split ( str_replace ( "\n" , '' , $bin_str ),8)); $_I = count ( $chars ); for ( $i = 0; $i < $_I ; $text_str .= chr ( bindec ( $chars [ $i ])), $i ); return $text_str ; } function text2bin( $txt_str ) { $len = strlen ( $txt_str ); $bin = '' ; for ( $i = 0; $i < $len ; $i ) { $bin .= strlen ( decbin (ord( $txt_str [ $i ])))<8? str_pad ( decbin (ord( $txt_str [ $i ])),8,0,STR_PAD_LEFT): decbin (ord( $txt_str [ $i ])); } return $bin ; } print text2bin( 'How are you gentlements?' ); ?> |
