ViewHelpers
f:split
The SplitViewHelper splits a string by the specified separator, which results in an array. The number of values in the resulting array can be limited with the limit parameter, which results in an array where the last item contains the remaining unsplit string.
This ViewHelper mimicks PHP's
explode function.
The following examples store the result in a variable because an array cannot be outputted directly in a template.
Examples
Split with a separator
<f:variable name="result"><f:split value="1,5,8" separator="," /></f:variable>
{0: '1', 1: '5', 2: '8'}Split using tag content as value
<f:variable name="result"><f:split separator="-">1-5-8</f:split></f:variable>
{0: '1', 1: '5', 2: '8'}Split with a limit
<f:variable name="result"><f:split value="1,5,8" separator="," limit="2" /></f:variable>
{0: '1', 1: '5,8'}Arguments
The following arguments are available for the split ViewHelper:

- Type
