参数长度 meaning in Chinese

pl parameter length

If the function , such as string replacement function , accepts both arrays and single characters as arguments , and if your argument list is not too long , consider writing a few redundant replacement statements , passing one character at a time , instead of one line of code that accepts arrays as search and replace arguments
如果一个字符串替换函数，可接受数组或字符作为参数，并且参数长度不太长，那么可以考虑额外写一段替换代码，使得每次传递参数是一个字符，而不是只写一行代码接受数组作为查询和替换的参数。
