in thread Reading and writing data to text file and to table

Hi Masters,

Please find the records which i formed below

$input{$EMPNO}[0]="DOB,Name,Empid,salary,Gross_salary,Department,Compa +ny"; $input{$EMPNO}[1]="Month,NET_Salary,";

The code which is used to put the records in table

{ my @data; my $table; foreach my $k (keys %input) { foreach (@{$input{$k}}) { chomp(); push( @{@data[$.]},( split /[,\n]/, $_)); } } $table .= "<table border=1>"; for my $i ( 0 .. $#data ) { $table .= "<tr>"; for ( @{@data[$i]}){ $table .= "<td>$_</td>\r\n"; } $table .= "</tr>"; } $table .= "</table>"; }

The output i want in a tabular format, when i run the above code i have error,Can't use an undefined value as an ARRAY reference

    Hi Masters,

    Good Morning, i am creating some records by adding some variables to it as mentioned below

    $report{}[0]="DOB,Name,Empid,salary,Gross_salary,Department,Company"; $report{}[1]="Month,NET_Salary,";

    I need to print these records to text file and also to a table

    subroutine{ my @data; my $table; open( F, "$File" ) || die("Could not open $File"); while ( my $line = <F> ) { chomp($line); push( @data,( split /[,\n]/, $line));} close(F); $table .= "<table border=1>"; for my $i ( 0 .. $#data ) { $table .= "<tr>"; for ( @data[$i]){ $table .= "<td>$_</td>\r\n"; } $table .= "</tr>"; } $table .= "</table>"; }

    When i execute this code, i am getting output as:

    MessageFile MessageFile MessageFile MessageFile MessageFile

    How can i read those records and print them into to text file and also to a table, any help on this, thanks in advance

    I have changed the code from for ( @data$i){ for column, i am getting output in single coulmn

    DOB Name Empid salary Gross_salary Department Company Month NET_Salary

    Its not displaying the data in row and column
