array_merge_recursive
Merge two or more arrays recursively
&reftitle.description;
arrayarray_merge_recursive
arrayarray1
array...
array_merge_recursive merges the elements of
one or more arrays together so that the values of one are appended
to the end of the previous one. It returns the resulting array.
If the input arrays have the same string keys, then the values for
these keys are merged together into an array, and this is done
recursively, so that if one of the values is an array itself, the
function will merge it with a corresponding entry in another array
too. If, however, the arrays have the same numeric key, the later
value will not overwrite the original value, but will be appended.
&reftitle.parameters;
array1
Initial array to merge.
...
Variable list of arrays to recursively merge.
&reftitle.returnvalues;
An array of values resulted from merging the arguments together.
