ASP.Net, check if a file exists pFile="data.txt" fileObj.FileExists(Server.MapPath(pFile))	PHP, check if a file exists $pFile="data.txt"; file_exists($pFile);
ASP.Net, Read a text file pFile="data.txt" xPage=fileObj.GetFile (Server.MapPath(pFile)) xSize=xPage.Size 'Get size of file in bytes xPage=fileObj.OpenTextFile (Server.MapPath(pFile)) temp=xPage.Read(xSize) 'Read file linkPage.Close	PHP, Read a text file $pFile="data.txt"; $temp=file_get_contents($pFile); //Read file
