Hey everyone! I just want to know if it is possible to get a certain character in a string, say the 3rd or 67th character. Also, how do you get the length of a string?

Thanks in advance for any replies!

@bokehAug 14.2005 — Position:
[code=php]$sub = substr($string, $position, $length)
3rd char: $sub = substr($string, 2, 1);
67th char $sub = substr($string, 66, 1);[/code]

length:
[code=php]$length = strlen($string);[/code]

@NogDogAug 14.2005 — An alternative way to refer to a specific character in a string is...
[code=php]
$string = "123456789";
$letter_nbr_5 = $string{4}; # numbering starts at 0
[/code]

[code=php]$random_number = rand(0, 1000);[/code]
