PHP程序查找字符串中的字符数

示例

<?php $my_string = "Hi there, this is a sample "; $len = mb_strlen($my_string); print_r("The number of characters in the string is "); echo $len; ?>

输出结果

The number of characters in the string is 27

上面定义了一个字符串，该字符串之间的空格超过了所需的空格-

$my_string = "Hi there, this is a sample ";

接下来，使用“strlen”函数计算字符串的长度。该长度分配给变量。这将给出字符串中存在的字符，包括空格-

$len = mb_strlen($my_string);

然后将计算出的长度打印在屏幕上-

print_r("The number of characters in the string is "); echo $len;
