ZF-12041: Zend filter underscore to camel case retains underscore if the string contains a numeric
When filtering a string with underscore to camel case, underscores are retained if the string contains a numeric.
$a = 'this_has_a_24_number'; $filter = new Zend_Filter_Word_UnderscoreToCamelCase(); echo $filter->filter($a);
I'm not entirely sure if this is the expected behaviour or not as you obviously cannot camel case numerics. However I feel the underscore should at least be removed after being passed through the filter.
