Replace

说明：Replace返回origin字符串中, search被replace替换后的新字符串。search区分大小写。
格式：

Replace(origin, search, replace string, count ...int) string

示例：

func ExampleReplace() {
	var (
		origin  = `golang is very nice!`
		search  = `golang`
		replace = `goframe`
		result  = gstr.Replace(origin, search, replace)
	)
	fmt.Println(result)
	// Output:
	// goframe is very nice!
}

ReplaceI

说明：ReplaceI返回origin字符串中, search被replace替换后的新字符串。search不区分大小写。
格式：

ReplaceI(origin, search, replace string, count ...int) string

示例：

func ExampleReplaceI() {
	var (
		origin  = `golang is very nice!`
		search  = `GOLANG`
		replace = `goframe`
		result  = gstr.ReplaceI(origin, search, replace)
	)
	fmt.Println(result)
	// Output:
	// goframe is very nice!
}

ReplaceByArray

说明：ReplaceByArray返回origin被一个切片按两个一组(search, replace)顺序替换的新字符串，区分大小写。
格式：

ReplaceByArray(origin string, array []string) string

示例：

func ExampleReplaceByArray() {
	{
		var (
			origin = `golang is very nice`
			array  = []string{"lang", "frame"}
			result = gstr.ReplaceByArray(origin, array)
		)
		fmt.Println(result)
	}
	{
		var (
			origin = `golang is very good`
			array  = []string{"golang", "goframe", "good", "nice"}
			result = gstr.ReplaceByArray(origin, array)
		)
		fmt.Println(result)
	}
	// Output:
	// goframe is very nice
	// goframe is very nice
}

ReplaceIByArray

说明：ReplaceIByArray返回origin被一个切片按两个一组(search, replace)顺序替换的新字符串，不区分大小写。
格式：

ReplaceIByArray(origin string, array []string) string

示例：

func ExampleReplaceIByArray() {
	var (
		origin = `golang is very Good`
		array  = []string{"Golang", "goframe", "GOOD", "nice"}
		result = gstr.ReplaceIByArray(origin, array)
	)
	fmt.Println(result)
	// Output:
	// goframe is very nice
}

ReplaceByMap

说明：ReplaceByMap返回origin中map的key替换为value的新字符串，区分大小写。
格式：

ReplaceByMap(origin string, replaces map[string]string) string

示例：

func ExampleReplaceByMap() {
	{
		var (
			origin   = `golang is very nice`
			replaces = map[string]string{
				"lang": "frame",
			}
			result = gstr.ReplaceByMap(origin, replaces)
		)
		fmt.Println(result)
	}
	{
		var (
			origin   = `golang is very good`
			replaces = map[string]string{
				"golang": "goframe",
				"good":   "nice",
			}
			result = gstr.ReplaceByMap(origin, replaces)
		)
		fmt.Println(result)
	}
	// Output:
	// goframe is very nice
	// goframe is very nice
}

ReplaceIByMap

说明：ReplaceIByMap返回origin中map的key替换为value的新字符串，不区分大小写。
格式：

ReplaceIByMap(origin string, replaces map[string]string) string

示例：

func ExampleReplaceIByMap() {
	var (
		origin   = `golang is very nice`
		replaces = map[string]string{
			"Lang": "frame",
		}
		result = gstr.ReplaceIByMap(origin, replaces)
	)
	fmt.Println(result)
	// Output:
	// goframe is very nice
}
