# PHPExcel User Documentation – Reading Spreadsheet Files
|
||
|
||
|
||
## Helper Methods
|
||
|
||
You can retrieve a list of worksheet names contained in a file without loading the whole file by using the Reader’s `listWorksheetNames()` method; similarly, a `listWorksheetInfo()` method will retrieve the dimensions of worksheet in a file without needing to load and parse the whole file.
|
||
|
||
### listWorksheetNames
|
||
|
||
The `listWorksheetNames()` method returns a simple array listing each worksheet name within the workbook:
|
||
|
||
```php
|
||
$objReader = PHPExcel_IOFactory::createReader($inputFileType);
|
||
|
||
$worksheetNames = $objReader->listWorksheetNames($inputFileName);
|
||
|
||
echo '<h3>Worksheet Names</h3>';
|
||
echo '<ol>';
|
||
foreach ($worksheetNames as $worksheetName) {
|
||
echo '<li>', $worksheetName, '</li>';
|
||
}
|
||
echo '</ol>';
|
||
```
|
||
> See Examples/Reader/exampleReader18.php for a working example of this code.
|
||
|
||
### listWorksheetInfo
|
||
|
||
The `listWorksheetInfo()` method returns a nested array, with each entry listing the name and dimensions for a worksheet:
|
||
|
||
```php
|
||
$objReader = PHPExcel_IOFactory::createReader($inputFileType);
|
||
|
||
$worksheetData = $objReader->listWorksheetInfo($inputFileName);
|
||
|
||
echo '<h3>Worksheet Information</h3>';
|
||
echo '<ol>';
|
||
foreach ($worksheetData as $worksheet) {
|
||
echo '<li>', $worksheet['worksheetName'], '<br />';
|
||
echo 'Rows: ', $worksheet['totalRows'],
|
||
' Columns: ', $worksheet['totalColumns'], '<br />';
|
||
echo 'Cell Range: A1:',
|
||
$worksheet['lastColumnLetter'], $worksheet['totalRows'];
|
||
echo '</li>';
|
||
}
|
||
echo '</ol>';
|
||
```
|
