| W | 2 | |
| 3 | ||
| 4 | ## Helper Methods | |
| 5 | ||
| 6 | 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. | |
| 7 | ||
| 8 | ### listWorksheetNames | |
| 9 | ||
| 10 | The `listWorksheetNames()` method returns a simple array listing each worksheet name within the workbook: | |
| 11 | ||
| 12 | ```php | |
| 13 | $objReader = PHPExcel_IOFactory::createReader($inputFileType); | |
| 14 | ||
| 15 | $worksheetNames = $objReader->listWorksheetNames($inputFileName); | |
| 16 | ||
| 17 | echo '<h3>Worksheet Names</h3>'; | |
| 18 | echo '<ol>'; | |
| 19 | foreach ($worksheetNames as $worksheetName) { | |
| 20 | echo '<li>', $worksheetName, '</li>'; | |
| 21 | } | |
| 22 | echo '</ol>'; | |
| 23 | ``` | |
| 24 | > See Examples/Reader/exampleReader18.php for a working example of this code. | |
| 25 | ||
| 26 | ### listWorksheetInfo | |
| 27 | ||
| 28 | The `listWorksheetInfo()` method returns a nested array, with each entry listing the name and dimensions for a worksheet: | |
| 29 | ||
| 30 | ```php | |
| 31 | $objReader = PHPExcel_IOFactory::createReader($inputFileType); | |
| 32 | ||
| 33 | $worksheetData = $objReader->listWorksheetInfo($inputFileName); | |
| 34 | ||
| 35 | echo '<h3>Worksheet Information</h3>'; | |
| 36 | echo '<ol>'; | |
| 37 | foreach ($worksheetData as $worksheet) { | |
| 38 | echo '<li>', $worksheet['worksheetName'], '<br />'; | |
| 39 | echo 'Rows: ', $worksheet['totalRows'], | |
| 40 | ' Columns: ', $worksheet['totalColumns'], '<br />'; | |
| 41 | echo 'Cell Range: A1:', | |
| 42 | $worksheet['lastColumnLetter'], $worksheet['totalRows']; | |
| 43 | echo '</li>'; | |
| 44 | } | |
| 45 | echo '</ol>'; | |
| 46 | ``` | |
| 47 | > See Examples/Reader/exampleReader19.php for a working example of this code. | |
