string find substring
Parameters:
string: String - string to search in
substring: String - substring to find
Return Value:
Number - zero-based position of the first sequence of characters that matches substring, -1 if not found

Syntax 3

Syntax:
string find [substring, indexStart]
Parameters:
string: String - string to search in
substring: String - substring to find
indexStart: Number - zero-based index which defines where find starts from

Examples

Example 1:
["Apples", "Oranges", "Pears"] find "Oranges"; // returns 1
Example 2:
[1, [2], [[3]]] find [[3]]; // returns 2 - does not work in OFP, returns -1
Example 3:
if (magazines player find "Strela" != -1) then { hint "You've got Strela!"; };
Example 4:
hint str ("japa is the man!" find "the man!"); // returns 8
Example 5:
"abc" find ""; // returns 0
Example 6:
"abcdefghijklmnopqrstuvxyz" find "z"; // returns 24 "abcdefghijklmnopqrstuvxyz" find ["z", 20]; // returns 24, better performance
Example 7:
"abcßdef" find "c" // 2 "abcßdef" find "ß" // 3 "abcßdef" find "d" // 5 - before forceUnicode forceUnicode 0; // since Arma 3 v2.02 "abcßdef" find "d" // 4

Using nil on either side of find will make the whole statement return Nothing:
_array = [1, 2, nil, 4, 5]; _result = _array find nil; hintSilent str (isNil "_result"); // true _result = nil find 1; hintSilent str (isNil "_result"); // true

If you want to return all occurences of a given string in a string use the following code. Thanks to sharp. for providing the code.
private _fnc_findStringsInString = { params ["_string", "_search"]; if (_string == "") exitWith { [] }; private _searchLength = count _search; private _return = []; private _i = 0; private _index = 0; while { _index = _string find _search; _index != -1 } do { _string = _string select [_index + _searchLength]; _i = _i + _index + _searchLength; _return pushBack _i - _searchLength; }; _return; }; ["Test,123,123,Test", "Test"] call _fnc_findStringsInString; // returns [0, 13]
