Strsrch
Evaluating: return strsrch("\nhello", "\n")
Result = 0
Evaluating: return strsrch("\r\nhello", "\n")
Result = -1
Evaluating: return strsrch("\n\rhello", "\n")
Result = 0
Sizeof/Strlen (sizeof returns the size as a strlen)__
Evaluating: return strlen("\nhello")
Result = 6
Evaluating: return strlen("\r\nhello")
Result = 6
Evaluating: return strlen("\n\rhello")
Result = 7
Directly accessing
Evaluating: return "\n"[0]
Result = 10
Evaluating: return "\r"[0]
Result = 13
Evaluating: return "\r\n"[0]
Result = 13
Evaluating: return "\r\n"[1]
Result = 0
(???????)
And finally, explode
Evaluating: return identify(explode("\r\n", ""))
Result = "({ "\r\n" })"
Evaluating: return identify(explode("hello\r\n", ""))
Result = "({ "h", "e", "l", "l", "o", "\r\n" })"
Evaluating: return identify(explode("\rhello\n", ""))
Result = "({ "\r", "h", "e", "l", "l", "o", "\n" })"
Evaluating: return identify(map(explode("hello\r\n", ""), (: $1[0] :)))
Result = "({ 104, 101, 108, 108, 111, 13 })"
Evaluating: return identify(map(explode("\rhello\n", ""), (: $1[0] :)))
Result = "({ 13, 104, 101, 108, 108, 111, 10 })"
Sscanf
Evaluating: string a, b; sscanf("\r\nAFB0\r\nmessage\r\n\0\r\n\r\n", "\r\n%s\r\n%s\r\n0\r\n\r\n", a, b); return ({ a, b }) ;
Result = ({ /* sizeof() == 2 */
"AFB0",
0
})
