strlen的參考例句
1.The strlen() function returns the length of a string. 函數的作用是:返回字符串長度。
2.When working with strings and you need to check that the string is either of a certain length you'd understandably would want to use the strlen() function. 當操作字符串並需要檢驗其長度是否滿足某種要求時,你想當然地會使用strlen()函數。
3.Calling isset() happens to be faster then strlen() because unlike strlen(), isset() is a language construct and not a meaning that it's execution does not require lookups and lowercase. 調用isset()恰拙比strlen()快,因為與先者不同的是,isset()作為一類言語構造,意味滅它的執行不需要函數查覓和字女大寫化。
