Load data from file in C - c

Question

I'm creating a simple C program - employee database... My data are stored in a .txt file, separated by commas and \n, so it looks like this:
data1,id1,name1
data2,id2,name2
What is the best way (in C, not C++) to load all data from the file and every value save as independent variable (e.g. p->data, p->id, p->name)?
This is the code I use to store data into variables (not into the file, variables just for the script):
void insert(emp *p,int n)
{
p=p+n;
printf("\nenter name of emplyee:");
_flushall();
gets(p->name);
printf("\nenter employee id:");
scanf("%d",&p->empid);
printf("\nenter salary of the emplyee:");
scanf("%d",&p->salary);
printf("\nenter phone no of the emplyee:");
flushall();
gets(p->ph);
}
And this script saves data to a file:
void sejv(emp *p,int n)
{
int i;
FILE *fptr;
fptr=fopen("ulozka.txt","w+");
if(fptr==NULL){
printf("Error opening file!");
getchar();
}
printf("Ukladani...");
for(i=0;i<n;i++)
{
fprintf(fptr,"%d,%s,%d,%s\n",p->empid,p->name,p->salary,p->ph);
p=p+1;
}
fclose(fptr);
exit(0);
}
All I need is to load the data to the main function so I can work with it.
EDIT:
I'm adding the rest of my code:
typedef struct employee
{
char name[20],ph[20];
int empid,salary;
}emp;
void main()
{
emp e;
emp *p;
int n=0,ch;
p=&e;
}
And "something" from the function I need to create...
void nacti(emp *p,int n)
{
int i;
FILE *fptr;
fptr=fopen("ulozka.txt","r");
if(fptr==NULL){
printf("Error opening file!");
getchar();
}
printf("Nacitani...");
//loading function
p=p+n;
fscanf(fptr,"%d,%[^\,],%d,%s", &p->empid, p->name, &p->salary,p->ph);
printf("%s", p->name);
}
I need a function that would read the data from the txt file by collumns and rows (a loop that would add the data from the first row to a p, then increase the value of p by 1, insert data from the second row and so on...)
Thank you for any advice...

Check the below code it can be done ad shown below:
struct data
{
int index;
int id;
char name[30];
};
int main ()
{
struct data p[3];
int i=0;
FILE *fp = fopen("input.txt","r+");
while(fscanf(fp,"%d,%d,%s",&p[i].index,&p[i].id,p[i].name) != EOF)
{
i++;
}
i=0;
while(i<3)
{
fprintf(fp,"%d %d %s\n",p[i].index,p[i].id,p[i].name);
i++;
}
fclose(fp);
}
