How to use

Dependency Injection

Reader

use Nealyip\Spreadsheet\Reader;
class Sth{
    protected $_reader;

    public function __construct(Reader $reader) {
        $this->_reader = $reader;
    }

    public function readFile($filename){
        $data = $this->_reader->toKeyValueArray($filename);

    }

Reader using generator

use Nealyip\Spreadsheet\Reader;
class Sth{
    protected $_reader;

    public function __construct(Reader $reader) {
        $this->_reader = $reader;
    }

    public function readFile($filename){
        $data = $this->_reader->toKeyValueArray($filename);
        foreach ($this->_reader->read($filename) as $item){
            // $item is a row in array form        
        } 
    }

Writer

use Nealyip\Spreadsheet\Writer;
class Sth{
    protected $_writer;

    public function __construct(Writer $writer) {
        $this->_writer = $writer;
    }

    public function writeFile($filename){

        $headers = ['Name', 'Gender', 'Age'];

        $this->_writer
            ->setup("report.xlsx")
            ->useSheet('Report')
            ->writeArray([['Tom','M','20'], ['Ann','F','24']], $headers)
            ->save();

    }

Writer using generator

use Nealyip\Spreadsheet\Writer;
class Sth{
    protected $_writer;

    public function __construct(Writer $writer) {
        $this->_writer = $writer;
    }
    
    /**    
     * Data source from DB/API etc
     * 
     * @return \Generator
     */
    protected function _data(){
        $data = [['Tom','M','20'], ['Ann','F','24']];
        foreach ($data as $d) {
            yield $d;
        }
    }


    public function writeFile($filename){

        $headers = ['Name', 'Gender', 'Age'];

        $this->_writer
            ->setup("report.xlsx")
            ->useSheet('Report')
            ->write($this->_data(), $headers)
            ->save();
    }

Write to local file

use Nealyip\Spreadsheet\Writer;
class Sth{
    protected $_writer;

    public function __construct(Writer $writer) {
        $this->_writer = $writer;
    }
    
    /**    
     * Data source from DB/API etc
     * 
     * @return \Generator
     */
    protected function _data(){
        $data = [['Tom','M','20'], ['Ann','F','24']];
        foreach ($data as $d) {
            yield $d;
        }
    }


    public function writeFile($filename){

        $headers = ['Name', 'Gender', 'Age'];

        $this->_writer
            ->setup("report.xlsx", false)
            ->useSheet('Report')
            ->write($this->_data(), $headers)
            ->save();
    }

Memory limit and execution timeout

If you have encounter memory exhaust problem, you may tune the memory limit by

ini_set('memory_limit', '1000M');

or for execution timeout

ini_set('max_execution_time', 300);
