Help for simple case

[paispatin]

Dear all,

I have 3 simple cases, and waiting for help:

1. case :
$a="abcdefg" (string)
How to get it as "efg" and "abc" and "cde"? (string result)

2. case :
$b=1234567 (numeric)
How to get it as 567 and 345 ? (still numeric result)

3. case :
How to generate a random number/string?

Thank you in advance.

1. Look into the Substr() function.

2. Again, look into the Substr() function.

3. Random number: look into the rand() or mt_rand() functions.

Random string: You'd most likely set up a for loop and use the chr() function. Below is an example.

// build a 5-character random string
$random_string = '';
for ($i = 0; $i < 5; $i++) {
    // generate number between 97 and 122, which are the 
    // ascii values of letters a-z (lowercase)
    $num = rand(97, 122);
    $random_string .= chr($num);
}
echo $random_string;

The pirate replies, "Arrrrr! It's driving me nuts!
