## Examples
### XLSX to html table
```php
echo SimpleXLSX::parse('book.xlsx')->toHTML();
```
or
```php
if ( $xlsx = SimpleXLSX::parse('book.xlsx') ) {
	echo '<table border="1" cellpadding="3" style="border-collapse: collapse">';
	foreach( $xlsx->rows() as $r ) {
		echo '<tr><td>'.implode('</td><td>', $r ).'</td></tr>';
	}
	echo '</table>';
} else {
	echo SimpleXLSX::parseError();
}
```
or styled html table
```php
if ( $xlsx = SimpleXLSX::parse('book_styled.xlsx') ) {
    echo $xlsx->toHTMLEx();
}
```
### XLSX read huge file, xlsx to csv
```php
if ( $xlsx = SimpleXLSX::parse( 'xlsx/books.xlsx' ) ) {
    $f = fopen('book.csv', 'wb');
	foreach ( $xlsx->readRows() as $r ) {
		fwrite($f, implode(',',$r) . PHP_EOL);
	}
	fclose($f);
} else {
	echo SimpleXLSX::parseError();
}
```
### XLSX get sheet names and sheet indexes
```php
// Sheet numeration started 0

if ( $xlsx = SimpleXLSX::parse( 'xlsx/books.xlsx' ) ) {
	print_r( $xlsx->sheetNames() );
	print_r( $xlsx->sheetName( $xlsx->activeSheet ) );
}

```
```
Array
(
    [0] => Sheet1
    [1] => Sheet2
    [2] => Sheet3
)
Sheet2
```
### Using rowsEx() to extract cell info
```php
$xlsx = SimpleXLSX::parse('book.xlsx');
print_r( $xlsx->rowsEx() );

```
```

### Select Sheet
```php
$xlsx = SimpleXLSX::parse('book.xlsx');
// Sheet numeration started 0, we select second worksheet
foreach( $xlsx->rows(1) as $r ) {
// ...
}
```
### Get sheet by index 
```php
$xlsx = SimpleXLSX::parse('book.xlsx');	
echo 'Sheet Name 2 = '.$xlsx->sheetName(1);
```
### XLSX::parse remote data
```php
if ( $xlsx = SimpleXLSX::parse('https://www.example.com/example.xlsx' ) ) {
	$dim = $xlsx->dimension(1); // don't trust dimension extracted from xml
	$num_cols = $dim[0];
	$num_rows = $dim[1];
	echo $xlsx->sheetName(1).':'.$num_cols.'x'.$num_rows;
} else {
	echo SimpleXLSX::parseError();
}
```
### XLSX::parse memory data
```php
// For instance $data is a data from database or cache    
if ( $xlsx = SimpleXLSX::parseData( $data ) ) {
	print_r( $xlsx->rows() );
} else {
	echo SimpleXLSX::parseError();
}
```
### Get Cell (slow)
```php
echo $xlsx->getCell(0, 'B2'); // The Hobbit
``` 
### DateTime helpers
```php
// default SimpleXLSX datetime format is YYYY-MM-DD HH:MM:SS (ISO, MySQL)
echo $xlsx->getCell(0,'C2'); // 2016-04-12 13:41:00

// custom datetime format
$xlsx->setDateTimeFormat('d.m.Y H:i');
echo $xlsx->getCell(0,'C2'); // 12.04.2016 13:41

// unixstamp
$xlsx->setDateTimeFormat('U');
$ts = $xlsx->getCell(0,'C2'); // 1460468460
echo gmdate('Y-m-d', $ts); // 2016-04-12
echo gmdate('H:i:s', $ts); // 13:41:00

// raw excel value
$xlsx->setDateTimeFormat( NULL ); // returns as excel datetime
$xd = $xlsx->getCell(0,'C2'); // 42472.570138889
echo gmdate('m/d/Y', $xlsx->unixstamp( $xd )); // 04/12/2016
echo gmdate('H:i:s', $xlsx->unixstamp( $xd )); // 13:41:00 
```
### Rows with header values as keys
```php
if ( $xlsx = SimpleXLSX::parse('books.xlsx')) {
    // Produce array keys from the array values of 1st array element
    $header_values = $rows = [];
    foreach ( $xlsx->rows() as $k => $r ) {
        if ( $k === 0 ) {
            $header_values = $r;
            continue;
        }
        $rows[] = array_combine( $header_values, $r );
    }
    print_r( $rows );
}
```
```

            [publisher] => Mallinson Rendel
            [ctry] => NZ
        )
)
```
### Debug
```php
use Shuchkin\SimpleXLSX;

ini_set('error_reporting', E_ALL );
ini_set('display_errors', 1 );

if ( $xlsx = SimpleXLSX::parseFile('books.xlsx', true ) ) {
	echo $xlsx->toHTML();
} else {
	echo SimpleXLSX::parseError();
}
```
### Classic OOP style 
```php
use SimpleXLSX;

$xlsx = new SimpleXLSX('books.xlsx'); // try...catch
if ( $xlsx->success() ) {
    foreach( $xlsx->rows() as $r ) {
        // ...
    }
} else {
    echo 'xlsx error: '.$xlsx->error();
}
```
