+# String Search
+
+#For this PHP code exercise, create a file named `string_search.php`. This file should contain
+# a function named `string_search()` which accepts two parameters.
+#The first is the string to search for (*needle*) and the second is the string to search
+# (*haystack*).
+
+#If *needle* is not found in *haystack*, `string_search()` should return `false`.
+#If *needle* is found in *haystack*, `string_search()` should return string formatted
+# as `Found 'needle' at index x` where `needle` is the first parameter and `x` is the starting index where `needle` was found.
+
+#For example, if *needle* were `search` and *haystack* were
+#`string search`, `string_search()` should return `Found 'search' at position 7`.
+
+#There are a few special cases:
+
+#1. If *needle* is an empty string, `string_search()` should return `false`.
+#2. If *needle* is found in *haystack* multiple times, `string_search()` should return the first index.
