<?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

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.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 = 1;

// Load the CSV records from the file:

$success = $csv->LoadFile('sample.csv');
if ($success != 1) {
    print $csv->LastErrorText . "\n";
    exit;
}

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

// Change "blue" to "magenta"
$success = $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 != 1) {
    print $csv->LastErrorText . "\n";
}
