We need a function that can transform a number (integer) into a string. What ways of achieving this do you know? Examples (input --> output):
converting a string to a number is essentially the reverse operationhowever, each string byte must be validatedif it's not a number, then your code has to have some way to handle itif the string is too long or the value is too large, your code has to have some way to handle that m...

PHP_FUNCTION(base_convert)首先对输入的参数进行了存储及校验,将$number以string的形式存储于zval中,并校验$frombase和$tobase是否在2和36之间,不在则报错返回。之后调用\_php\_math_basetozval()函数根据frombase将存储于zval中的string转换成对应的数值,代码如下: View Code 由上面的代码可以看到,\_php_math_...
