在php中读取文件我们需要使用file_get_contents或fopen来打开文件然后再读取了，file_get_contents函数读文件比fopen要方便，写文件需要fopen函数与file_put_contents或fwrite合作才可以实例下面我来介绍下。

php写文件的方法
实例一
| 代码如下 |
复制代码 |
$filename = 'test.txt';
$filename = dirname ( __FILE__ ) . '/' . $filename;
if (file_exists ( $filename )) {
if (! is_writable ( $filename )) {
exit('is not writable');
}
$handle = fopen ( $filename, "a+b" );
$content = 'this is test words';
$content .= "n";
fwrite($handle, $content);
fclose ( $handle );
} else {
exit('file is not exists');
} |

$contents = fread($handle, filesize ($filename));
//$contents = stream_get_contents($handle); // 也可以用方法替换上一行
$contents = explode("n", $contents);
fclose ( $handle );
