A string whose length is greater than zero is always evaluated as True when resolved to a Boolean function, even if its value is the string 'false'.

When told to print no more than n bytes, snprintf guarantees that it creates a string of length no more than n-1, with a null terminator at the end of the string.

I can get the character count (from the string length) and the word count (by splitting the string by Spaces and counting the results).
我获得了字符计数(计算字符串长度)和单词数(使用空格将字符串断开并计算结果)。
So, to get the correct length of string encoded in utf-8, you have to use mb_strlen (string, "utf-8") instead of just strlen (string).
因而，要获得以utf - 8编码的字符串的正确长度，必须使用mb_strlen (string，“ utf - 8 ”)，而不只是strlen (string)。
Some of the typical string-related checks would validate whether an empty string has 0 length, accessing out-of-index results in an error message or exception, and so on.
与字符串相关的一些典型的检查，会验证空字符串的长度是否为 0，访问范围超出索引是否导致错误消息或异常，等等。
Data length: For example, an account number must have a particular string length, a minimum string length, or a maximum string length.
数据长度：例如，帐目编码必须具备指定长度、最小长度或者最大长度。
The md5() function hashes whatever string is fed to it and turns it into a 32-character fixed-length string.
md5()函数可以散列反馈的任何字符串，并将其转变为固定长度为 32 个字符的字符串。
You can also use string functions to report string attributes such as length or position of a sub-string, for example
还可以使用string函数来报告字符串属性，如子串的长度或位置，例如
The getTagAndLengthBytes() method will prepend the name-string tag byte (context-specific tag number 0) and length bytes before the SEQUENCE and return the complete name-string structure.
getTagAndLengthBytes()方法会在SEQUENCE 前面附加 name-string标签字节（上下文特定的标签数字0）以及长度字节，并返回完整的 name-string结构。
If the argument is an empty sequence, fn: string (seq) will return a zero-length string, but the other function returns an empty sequence.
如果参数是空序列，fn：string (seq)将返回长度为零的字符串，另一个函数则返回空白序列。
The description column is a variable-length character string, so it expects a string (which you indicate by enclosing the character data within single quotes).
description列是长度可变的字符串，所以它预计是一个字符串(通过将字符数据括在单引号中指明)。
An empty string contains no characters and has length 0, but other than that, it is the same as any other string.
空字符串不包含字符，长度为0，除此之外，都与其他字符串是一样的。
Using a binary search tree or dividing the string into segments as long as the square root of the length of the string will solve the problem.
