php入門教程一(對文件訪問實現)
對文件訪問實現的源代碼。主要講到php教程操作文件以及xml文檔實例方法。
<?php
// 創建一個新的pdf文檔句柄
$pdf = cpdf_open(0);
// 打開一個文件
cpdf_open_file($pdf);
// 開始一個新頁面(a4)
cpdf_begin_page($pdf, 595, 842);
// 得到並使用字體對象
$arial = cpdf_findfont($pdf, "arial", "host", 1);
cpdf_setfont($pdf, $arial, 10);
// 輸出文字
cpdf_show_xy($pdf, "this is an exam of pdf documents, it is a good lib,",50, 750);
cpdf_show_xy($pdf, "if you like,please try yourself!", 50, 730);
// 結束一頁
cpdf_end_page($pdf);
// 關閉並保存文件
cpdf_close($pdf);// 如果要直接輸出到客戶端的話，把下面的代碼加上
$buf = cpdf_get_buffer($pdf);
$len = strlen($buf);
header("content-type: application/pdf");
header("content-length: $len");
header("content-disposition: inline; filename=pie_php.pdf");
print $buf;
cpdf_delete($pdf);
?>
xml文件
<?php
$dom = new domdocument();
$dom->load("order.xsl");
$proc = new xsltprocessor;
$xsl = $proc->importstylesheet($dom);$xml = new domdocument();
$xml->load('order.xml');
$string = $proc->transformtoxml($xml);
echo $string;
?>
