python - Can this PY code be converted into PHP?

As a PY novice, I think this PY code is like a holy book. Can anyone help me convert it to PHP?

<code>def str2hex(s):
        r=""
        for i in s[:8]:
            t=hex(ord(i))[2:]
            if len(t)==1:
                t="0"+t
            r+=t
        for i in range(16):
            r+=hex(int(15*random()))[2:]
        return r

    def getkey(s):
        #returns 1896220160
        l2=[i for i in s]
        l4=0
        l3=0
        while l4<len(l2):
            l5=l2[l4]
            l6=ord(l5)
            l7=l6<<((l4%4)*8)
            l3=l3^l7
            l4+=1
        return l3
        pass</code>

The code is well written and not professional. . .
