A simple PHP to "copy" data from one source to another
PHP >= 5.6
Install library with composer
composer require jackal/copycat
require_once __DIR__.'/vendor/autoload.php';
$reader = new \Jackal\Copycat\Reader\ArrayReader([
['col1' => 'value1','col2' => 'value2'],
['col1' => 'value3','col2' => 'value4'],
/*...*/
]);
$workflow = new \Jackal\Copycat\Workflow($reader);
$workflow->addWriter(new \Jackal\Copycat\Writer\SQLFileWriter('test_table','test_table.sql'));
$workflow->process();
echo file_get_contents(__DIR__.'/test_table.sql');
$reader = new \Jackal\Copycat\Reader\ArrayReader([
['value1'],
['value2'],
/*...*/
]);
$workflow = new \Jackal\Copycat\Workflow($reader);
$workflow->addWriter(new \Jackal\Copycat\Writer\ArrayWriter($outputArray));
$workflow->process();
var_dump($outputArray);
With Filters you can apply logic to exclude certain values from the output.
/*[...]*/
/*Define wich column to apply filter*/
$workflow->addFilter(new NotBlankFilter('col1'));
/*[...]*/
Filters are callable objects, you can define your own filter
/*[...]*/
/*Define custom filter*/
$workflow->addFilter(function($values){
return $values['col1'] > 0;
});
/*[...]*/
With Converter you can modify values to the output.
/*[...]*/
/*Define custom filter*/
$workflow->addConverter(new DatetimeToStringConverter('col1'));
/*[...]*/
You can set your own converter
/*[...]*/
//apply custom converter
$workflow->addConverter(function ($values){
foreach ($values as &$value) {
if ($value == 'to convert') {
$value = 'converted';
}
}
return $values;
});
/*[...]*/
Is it possible to sort output values
/*[...]*/
//add sorter
$workflow->addSorter(new AscendingSorter('col1'));
/*[...]*/
If you want to sort values basing on multiple columns, you can just add multiple params. Use with care! this method could create performance issues on large input data
/*[...]*/
//add sorter
$workflow->addSorter(new AscendingSorter('col1','col2','col3',/*...*/));
