Method:createHeaders

header creator

uses prefix and creates a header for each column suffixed by a numeric value

by default the first row is interpreted as headers but if we have a csv file with data only and no headers it becomes really annoying to work with the current loaded data.

this function will create a set dinamically generated headers and make the current headers accessable with the row handling functions

Note: that the csv file contains only data but no headers sample of a csv file "my_cool.csv"

john,13,knows magic
tanaka,8,makes sushi
jose,5,dances salsa

checks if the csv file was loaded

$csv = new File_CSV_DataSource;
if (!$csv->load('my_cool.csv')) {
die('can not load csv file');
}

dump current headers

var_export($csv->getHeaders());

standard output

array (
0 => 'john',
1 => '13',
2 => 'knows magic',
)

generate headers named 'column' suffixed by a number and interpret the previous headers as rows.

$csv->createHeaders('column')

dump current headers

var_export($csv->getHeaders());

standard output

array (
0 => 'column_1',
1 => 'column_2',
2 => 'column_3',
)

build a relationship and dump it

var_export($csv->connect());

output

array (
0 =>
array (
'column_1' => 'john',
'column_2' => '13',
'column_3' => 'knows magic',
),
1 =>
array (
'column_1' => 'tanaka',
'column_2' => '8',
'column_3' => 'makes sushi',
),
2 =>
array (
'column_1' => 'jose',
'column_2' => '5',
'column_3' => 'dances salsa',
),
)
