C function like in_array in PHP

Question

<?php
$os = array("Mac", "NT", "Irix", "Linux");
if (in_array("Irix", $os)) {
    echo "Got Irix";
}
if (in_array("mac", $os)) {
    echo "Got mac";
}
?>

Is there some function in C which does similar thing to in_array in PHP?

Nope, you have to implement it yourself :) btw, in_array() is case sensitive, so in_array('mac', $s) will be false. — Ja͢ck

Nope, but you can implement like this

typedef int (*cmpfunc)(void *, void *);

int in_array(void *array[], int size, void *lookfor, cmpfunc cmp)
{
    int i;

    for (i = 0; i < size; i++)
        if (cmp(lookfor, array[i]) == 0)
            return 1;
    return 0;
}

int main()
{
    char *str[] = {"this is test", "a", "b", "c", "d"};

    if (in_array(str, 5, "c", strcmp))
        printf("yes\n");
    else
        printf("no\n");

    return 0;
}
