例如,`split("red,green,blue", colors, ",")`将把字符串拆分为`colors`数组:`colors[1]="red"`, `colors[2]="green"`, `colors[3]="blue"`。 5. tolower函数和toupper函数:tolower函数将字符串转换为小写,toupper函数将字符串转换为大写。它们的语法是:`tolower(string)`和`toupper(string)`。
split(String, Array [, Sep]) 将由String 参数指定的输入字段分割成多个元素并存储到 Array 数组中,每个数组元素对应一个字段。字段之间由 Sep 参数指定的分隔符隔开。如果 Sep 参数未指定,则使用空格作为分隔符。返回分割的数量。 tolower(String)
