Transformers

$job->transform($type, $options);

• $type: the type of the transformer (trim, etc).
• $options: an array containing the transformer options.

Trim

Syntax

$job->transform('trim', $options);

Options

Name	Type	Default	Description
type	string	'both'	The options trim | all | both will trim both sides, ltrim | start | left will trim the left side and rtrim | end | right will trim the right side of the string.
mask	string	" \t\n\r\0\x0B"	The stripped characters. Simply list all characters that you want to be stripped. With .. you can specify a range of characters.

Examples

Strip whitespace from the beginning and end of a string in all transformation columns:

$job->transform('trim');

Strip pipes from the beginning of a string in specific transformation columns:

$options = [
    'columns' => ['id', 'name'],
    'type' => 'left',
    'mask' => '|'
];

$job->transform('trim', $options);

Json Encode

$job->transform('JsonEncode', $options);
