## Basics
Creating a new PHPExcel Object.
```
    $this->PHPExcel = new PHPExcel();
```

### Working with sheets

Creating a new sheet:
```
    $this->activeSheet = $this->PHPExcel->createSheet();
```
Getting the active Sheet:
```
    $this->activeSheet = $this->PHPExcel->getActiveSheet();
```
Setting the active sheet:
```
    $this->PHPExcel->setActiveSheetIndex(2);
```
Renaming a worksheet:
```
    $this->activeSheet->setTitle($title);
```





## Writing to cells
Text can be added to a cell using `setCellValue($colRow, $data)`
`$colRow` - The column and row to write to (i.e. 'A2')
`$data` - The data to write

```
    $this->activeSheet
        ->setCellValue($colRow, $data);

    $this->activeSheet
        ->setCellValue("B1", $data)
        ->setCellValue("B2", $data);
        ->setCellValue("B5", $data);
```

```
    $this->activeSheet->setCellValueByColumnAndRow($column, $row, $data);
```

```
    $this->activeSheet->setCellValueExplicit($coord, $value, $dataType);
    $this->activeSheet->setCellValueExplicitByColumnAndRow($col, $row, $value, $dataType);
```

#### Writing from arrays
A 2-dimensional array can be written to the current sheet usng `fromArray($twoDimArray)`
* `$twoDimArray` - the 2D array to be written
* `$useWhenNull` - what to use if there is a null value
* `$topLeftCorner` -  where the top left corner should be.

```
    $this->activeSheet->fromArray($sheet);
    $this->activeSheet->fromArray($sheet, "", $colRow);
```

Or the array can be written manually by looping through the array and calling `setCellValue`
```
    foreach($rows as $row => $columns) {
        foreach($columns as $column => $data) {
            $this->activeSheet->setCellValue($column.$row, $data);
        }
    }
```

### Formatting Cells
**Setting column width**
A single column:
```
    $this->activeSheet
        ->getColumnDimension($colString)
        ->setWidth($width);
```
Default width for all columns on a sheet:
```
    $this->activeSheet
        ->getDefaultColumnDimension()
        ->setWidth($width);
```
Auto size
```
    $this->activeSheet
        ->getColumnDimension("A")
        ->setAutoSize(true);
```
**Setting row height**
A single row:
```

```
Default row height for an entire sheet:
```
    $this->activeSheet
        ->getDefaultRowDimension()
        ->setRowHeight($height);
```

## Styling Cells
```


    $this->activeSheet
        ->getStyle("B1")
        ->getAlignment()
        ->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_RIGHT);

    $styleArray = array(
        'font' => array(
            'bold' => true,
        )
    );

    $this->activeSheet
        ->getStyle("B1:F1")
        ->applyFromArray(array("font" => array( "bold" => true)));
```

```
->getStyle("D1:D20")->getAlignment()->setWrapText(true);
```

Setting default styles for the active sheet
```
    $this->activeSheet
        ->getDefaultStyle()
        ->applyFromArray($this->defaultStyle);
```

## Setting file properties
```
$this->PHPExcel->getProperties()->setCreator("");
$this->PHPExcel->getProperties()->setLastModifiedBy("");
$this->PHPExcel->getProperties()->setTitle("");
$this->PHPExcel->getProperties()->setSubject("");
$this->PHPExcel->getProperties()->setDescription("..");
$this->PHPExcel->getProperties()->setKeywords("");
$this->PHPExcel->getProperties()->setCategory("");
```
