<?php

// Load the following CSV:

//  Name;City;Weight
//  John;Chicago;180
//  Lisa;Denver;120

// Indicate that the 1st line contains column names.

$csv->LoadFile('qa_data/csv/insertColumnTest.csv');

// We can insert a column before the 1st column.
$csv->InsertColumn(0);

// The CSV now looks like this:

//  ;Name;City;Weight
//  ;John;Chicago;180
//  ;Lisa;Denver;120

// Set the cells in column 0.

// We now have:

//  id;Name;City;Weight
//  100;John;Chicago;180
//  101;Lisa;Denver;120

// Insert a new column between City and Weight
// In other words, add a new column before the Weight column.

echo $csv->SaveToString(), "\n";

// We now have:

//  id;Name;City;;Weight
//  100;John;Chicago;;180
//  101;Lisa;Denver;;120

// Set the cells in the new column:

$csv->SetColumnName($weightColumn, 'Height');
$csv->SetCell(0, $weightColumn, '6\' 2"');
$csv->SetCell(1, $weightColumn, '5\' 7"');

echo $csv->SaveToString(), "\n";

// We now have:

//  id;Name;City;Height;Weight
//  100;John;Chicago;"6' 2""";180
//  101;Lisa;Denver;"5' 7""";120
