php目录遍历函数opendir用法实例_php技巧
本文实例讲述了php目录遍历函数opendir用法。分享给大家供大家参考。具体分析如下:
opendir()函数的作用是:打开目录句柄,如果该函数成功运行,将返回一组目录流(一组目录字符串),如果失败将返回错误[error],你可以在函数的最前面加上“@”来隐藏错误.
syntax语法:opendir(directory,context) parameter
参数:description
描述:directory required. specifies the directory to stream
必要参数,指定目录对象,可选参数,指定需要处理的目录对象的context,这个context包括了一组选项,它可以对文本流的显示方式进行改变,实例代码如下:
// open a known directory, and proceed to read its contents
if (is_dir($dir))
{
if ($dh = opendir($dir)) {
while (($file = readdir($dh)) !== false) {
echo "filename: $file : filetype: " . filetype($dir . $file) . "n"."
";
}
closedir($dh);
}
}
?>
希望本文所述对大家的PHP程序设计有所帮助。
