<?php

//  This example program loads a file (sample.csv)
//  that contains this content:
// 
//  year,color,country,food
//  2001,red,France,cheese
//  2005,blue,"United States",hamburger
//  2008,green,Italy,pasta
//  1998,orange,Japan,sushi
// 
//  The first row contains the column names.
//  This file is available at:
//  http://www.chilkatsoft.com/testData/sample.csv

$csv = new COM("Chilkat.Csv");

//  Prior to loading the CSV file, indicate that the 1st row
//  should be treated as column names:
$csv->HasColumnNames = true;

//  Load the CSV records from the file:

$success = $csv->LoadFile('sample.csv');
if ($success != true) {
    print $csv->lastErrorText() . "\n";
    exit;
}

//  Change "cheese" to "baguette"
//  ("cheese" is at row=0, column=3
$csv->SetCell(0,3,'baguette');

//  Change "blue" to "magenta"
$csv->SetCell(1,1,'magenta');

//  Write the updated CSV to a string and display:

$csvDoc = $csv->saveToString();
print $csvDoc . "\n";

//  Save the CSV to a file:
$success = $csv->SaveFile('out.csv');
if ($success != true) {
    print $csv->lastErrorText() . "\n";
}
