How to recursively get a list of all files with specific extension from directory include subdirectories in C

Answer 1

#include <stdio.h>
#include <dirent.h>
#include <string.h>

void listOfAllFilesWithSpecificExtension(char *mainpath) {
    char path[1024];
    struct dirent *drnt;
    DIR *dir = opendir(mainpath);

	if (!dir)
        return;
    
	while ((drnt = readdir(dir)) != NULL) {
        if (strcmp(drnt->d_name, ".") != 0 && strcmp(drnt->d_name, "..") != 0) {
			if (strcmp(drnt->d_name + strlen(drnt->d_name) - 4, ".php") == 0) {
				printf("%s\n", drnt->d_name);
			}
			
            strcpy(path, mainpath);
            strcat(path, "/");
            strcat(path, drnt->d_name);

            listOfAllFilesWithSpecificExtension(path);
        }
    }

    closedir(dir);
}
  
int main(int argc, char **argv) 
{ 
    listOfAllFilesWithSpecificExtension("c:\\xampp\\htdocs\\allonpage.com");

	return 0;
}
