`for`

Loop view helper which can be used to iterate over arrays. Implements what a basic foreach()-PHP-method does.

= Examples =

<f:for each="{0:1, 1:2, 2:3, 3:4}" as="foo">{foo}</f:for> 1234


  <f:for each="{fruit1: 'apple', fruit2: 'pear', fruit3: 'banana', fruit4: 'cherry'}" as="fruit" key="label">
<li>{label}: {fruit}</li>

  </f:for>

fruit1: apple
fruit2: pear
fruit3: banana
fruit4: cherry


  <f:for each="{0:1, 1:2, 2:3, 3:4}" as="foo" iteration="fooIterator">
<li>Index: {fooIterator.index} Cycle: {fooIterator.cycle} Total: {fooIterator.total}{f:if(condition: fooIterator.isEven, then: ' Even')}{f:if(condition: fooIterator.isOdd, then: ' Odd')}{f:if(condition: fooIterator.isFirst, then: ' First')}{f:if(condition: fooIterator.isLast, then: ' Last')}</li>

  </f:for>

Index: 0 Cycle: 1 Total: 4 Odd First
Index: 1 Cycle: 2 Total: 4 Even
Index: 2 Cycle: 3 Total: 4 Odd
Index: 3 Cycle: 4 Total: 4 Even Last
