<?php $file = "1.txt" ; // 文件的真实地址(支持url,不过不建议用url) if ( file_exists ( $file )) { header( 'Content-Description: File Transfer' ); header( 'Content-Type: application/octet-stream' ); header( 'Content-Disposition: attachment; filename=' . basename ( $file )); header( 'Content-Transfer-Encoding: binary' ); header( 'Expires: 0' ); header( 'Cache-Control: must-revalidate, post-check=0, pre-check=0' ); header( 'Pragma: public' ); header( 'Content-Length: ' . filesize ( $file )); ob_clean(); flush (); readfile( $file ); exit ; } ?> |
希望本文所述对大家的php程序设计有所帮助。
