ArrayMerge
This function creates a new array with data from the two passed arrays.
To add all the data from one array into another without creating a new array see the built in function ArrayAppend(arr1, arr2, true).
Method Signature
ArrayMerge(array1=[array], array2=[array], leaveIndex=[boolean])Arguments
array1
array
true
The first array to merge
array2
array
true
The second array to merge
leaveIndex
boolean
true
Set to true maintain value indexes - if two values have the same index it will keep values from array1
false
Examples
Standard function syntax
Merge two arrays resulting in a single re-indexed array. All elements of both arrays are preserved.
fruit = [
"apple",
"banana",
"orange"
];
veggies = [
"tomato",
"carrot",
"corn",
"peas",
"peppers"
];
healthyFoods = arrayMerge( fruit, veggies );
writeOutput( arrayToList( healthyFoods ) );
Result: apple,banana,orange,tomato,carrot,corn,peas,peppers
Member function syntax
Merge two arrays resulting in a single re-indexed array. All elements of both arrays are preserved.
fruit = [
"apple",
"banana",
"orange"
];
veggies = [
"tomato",
"carrot",
"corn",
"peas",
"peppers"
];
healthyFoods = fruit.merge( veggies );
writeOutput( arrayToList( healthyFoods ) );
Result: apple,banana,orange,tomato,carrot,corn,peas,peppers
Example where leaveIndex parameter is true
Merge two arrays resulting in a single re-indexed array. Where the both arrays have elements in the same position, only values from the first array are included in the result. Valid using standard or member function syntax.
Note how the first three elements of the veggies array are not merged because the fruit array already has values for elements 1-3.
fruit = [
"apple",
"banana",
"orange"
];
veggies = [
"tomato",
"carrot",
"corn",
"peas",
"peppers"
];
healthyFoods = arrayMerge( fruit, veggies, true );
writeOutput( arrayToList( healthyFoods ) );
Result: apple,banana,orange,peas,peppers
Additional Examples
aNames = array( 10412, 42, 33, 2, 999, 12769, 888 );
aNames2 = array( 33, "b", "c", "d", "e", "f", "g" );
dump( arrayMerge( aNames, aNames2 ) );
// member function
dump( aNames.merge( aNames2 ) );
dump( aNames.merge( aNames2, true ) );
