使用方法:
只读:$ifile = new iFile('test.txt','r');
读写:$ifile = new iFile('test.txt','w');
快读:$ifile = new iFile('test.txt','dr');
快写:$ifile = new iFile('test.txt','w','测试一下咯');
读取文件内容:$ifile->getFileData();
显示读取/快读数据:echo $ifile->Data;
写入文件内容:$ifile->WriteFile('测试一下咯',3);
关闭文件句柄:$ifile->ColseFile();
注意:写入/快写后自动关闭文件句柄.
