Parse callbacksParse callables are invoked by yaml_parse, yaml_parse_file or yaml_parse_url functions when a registered YAML tag is encountered. The callback is passed the tagged entity's value, the tag, and flags indicating the scalar entity style. The callback must return the data that the YAML parser should emit for this entity. Example #1 Parse callback example
The above example will output something similar to: array(3) { [0]=> string(5) "World" [1]=> string(14) "!example/hello" [2]=> int(1) } array(1) { ["greeting"]=> string(11) "Hello World" } |
