strlen string

is the internal implementation of the count (array) and strlen (string) of PHP a direct display of a length variable, or how many elements are there in a number of times?It's about my understanding of the efficiency of these 2 functions.I hope that

/// /// Obtain the first LEN character of the string, in the unit of Chinese character width. /// /// /// /// Public static string strlen (string STR, int Len ){ String strnew = ""; Int strlen = 0; For (INT I = 0; I If (INT) STR [I] & gt; 255

# Include int main (void) {char * str = "123456789"; char p [10] = {0}; char t [10] = "123 "; char a [10] = {'1', '2', '3', '4', '5', '\ 0', '7 ', '8'}; char B; int c; long d; double e; printf ("% d \ n", sizeof (B); // 1 [Note: variable type]
