php入门教程一(对文件访问实现)

对文件访问实现的源代码。主要讲到php教程操作文件以及xml文档实例方法。

<?php
// 创建一个新的pdf文档句柄
$pdf = cpdf_open(0);
// 打开一个文件
cpdf_open_file($pdf);
// 开始一个新页面(a4)
cpdf_begin_page($pdf, 595, 842);
// 得到并使用字体对象
$arial = cpdf_findfont($pdf, "arial", "host", 1);
cpdf_setfont($pdf, $arial, 10);
// 输出文字
cpdf_show_xy($pdf, "this is an exam of pdf documents, it is a good lib,",50, 750);
cpdf_show_xy($pdf, "if you like,please try yourself!", 50, 730);
// 结束一页
cpdf_end_page($pdf);
// 关闭并保存文件
cpdf_close($pdf);

// 如果要直接输出到客户端的话，把下面的代码加上

$buf = cpdf_get_buffer($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;
?>

order.sls

<?xml version="1.0" encoding='gb2312' ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/xsl/transform">

          <xsl:with-param name="sortorder" select="$order" />
        </xsl:apply-templates>
      </body>
    </html>
</xsl:template>

<xsl:template match="order">
    <xsl:param name="sortcolumn" />
    <xsl:param name="sortorder" />
    <table border="1">
      <tr>
        <th>订单号</th>
        <th>id</th>
        <th>说明</th>
        <th>价格</th>
        <th>数量</th>
        <th>合计</th>
      </tr>
      <xsl:apply-templates select="item">
      </xsl:apply-templates>
    </table>
</xsl:template>
<xsl:template match="item">
    <tr>
      <td><xsl:value-of select="../account" /></td>
      <td><xsl:value-of select="sku" /></td>
      <td><xsl:value-of select="description" /></td>
      <td><xsl:value-of select="priceper" /></td>
      <td><xsl:value-of select="quantity" /></td>
      <td><xsl:value-of select="subtotal" /></td>
    </tr>
</xsl:template>
</xsl:stylesheet>
