[SOLVED] basic string manipulation

[HoTDaWg]

lmfao im fresh outta turing so forgive me lol

here is a basic string manipulation application assigning a letter from a string onto an array:

<?php
$stringofletters = "abcdefghijklmnopqrstuvwxyz";
$letters = array();
for ($i = 1; $i <= strlen($stringofletters); $i ++)
{
$letters($i) = $stringofletters($i); #This is where the problem is
}
?>

im having trouble with pointing to a specific character in the stringofletters. here is the error im getting:

Fatal error: Can't use function return value in write context in C:\xampp\htdocs\learnphp\hacks\test.php on line 6

how do i go about referring to a specific character in the string?

<?php
$stringofletters = "abcdefghijklmnopqrstuvwxyz";
$letters = array();
for ($i = 1; $i <= strlen($stringofletters); $i ++)
{
   $letters[$i] = $stringofletters[$i]; #This is where the problem is
}
?>

do you happen VB programer before done PHP?

You are using () instead of [] for accessing an array.

oh hahah thanks

thank you its a force of habit from turing:P i guess vb might have the syntax i wouldnt know.

but now im getting this error:

Fatal error: Call to undefined function abcdefghijklmnopqrstuvwxyz() in C:\xampp\htdocs\learnphp\hacks\test.php on line 6

im guessing this has to do with my inital question

here is the updated code

<?php
$stringofletters = "abcdefghijklmnopqrstuvwxyz";
$letters = array();
for ($i = 1; $i <= strlen($stringofletters); $i ++)
{
$letters[$i] = $stringofletters($i);
}
?>

how do i refer to a specific character in that string?

thanks

actually, you need to be using { }

 

$stringofletters = "abcdefghijklmnopqrstuvwxyz";

echo $stringofletters{4}; // output: e

 

but looking at your code, if you have php5+ you can just use str_split to accomplish the same thing.

excellent thanks very much!

also, if you don't have php5+ you can use range instead:

 

$letters = range('a','z');
