本文实例讲述了php文件读取方法。分享给大家供大家参考。具体如下:

<&#63;php 
$file = fopen("Test//file.txt", "r"); //打开文件 
echo fgetc($file); //读取文件中的一个字符 
fclose($file); //关闭文件 
&#63;> 

<&#63;php 
$file = fopen("Test//file.txt", "r"); //打开文件 
echo fgets($file); //读取文件中的一行 
fclose($file); //关闭文件 
&#63;> 

<&#63;php 
$file = fopen("Test//file.txt", "r"); 
echo fread($file, 20); //读取文件中的前20个字符 
fclose($file); 
&#63;> 

<&#63;php 
$filename = "Test//file.txt"; 
$file = fopen($filename, "r"); 
$filesize = filesize($filename); //获取文件长度 
echo fread($file, $filesize); //获取文件全部内容 
fclose($file); 
&#63;>

希望本文所述对大家的php程序设计有所帮助。
