Method:setHeaders header injector uses a $list of values which wil be used to replace current headers. Note: that given $list must match the length of all rows. known as symmetric. see isSymmetric() and getAsymmetricRows() methods Also, that current headers will be used as first row of data and consecuently all rows order will change with this action. sample of a csv file "my_cool.csv" name,age,skill
john,13,knows magic
tanaka,8,makes sushi
jose,5,dances salsa load the library and csv file require_once 'File/CSV/DataSource.php';
$csv = new File_CSV_DataSource;
$csv->load('my_cool.csv');lets dump currently loaded data var_export($csv->connect()); output array (
0 =>
array (
'name' => 'john',
'age' => '13',
'skill' => 'knows magic',
),
1 =>
array (
'name' => 'tanaka',
'age' => '8',
'skill' => 'makes sushi',
),
2 =>
array (
'name' => 'jose',
'age' => '5',
'skill' => 'dances salsa',
),
) And now lets create a new set of headers and attempt to inject them into the current loaded dataset $new_headers = array('a', 'b', 'c');
var_export($csv->setHeaders($new_headers));output true Now lets try the same with some headers that do not match the current headers length. (this should fail) $new_headers = array('a', 'b');
var_export($csv->setHeaders($new_headers));output false now let's dump whatever we have changed var_export($csv->connect()); output array (
0 =>
array (
'a' => 'name',
'b' => 'age',
'c' => 'skill',
),
1 =>
array (
'a' => 'john',
'b' => '13',
'c' => 'knows magic',
),
2 =>
array (
'a' => 'tanaka',
'b' => '8',
'c' => 'makes sushi',
),
3 =>
array (
'a' => 'jose',
'b' => '5',
'c' => 'dances salsa',
),
) - Argument array $list a collection of names to use as headers,
- Visibility public
- Returns boolean fails if data is not symmetric
- Also see isSymmetric(), getAsymmetricRows(), getHeaders(), createHeaders()
