hi

I'm a newbie with php and need a little help if anyone could provide it. i'm trying to load a list of words from a file and lower the case of the words and remove duplicates. It all works except the changing the words to lower case, but it doesn't through up any errors. This is only part of my script but it's that, that doesn't work. like i say i'm a php newbie so it might be something stupid. Any help appreciated

if (is_uploaded_file($userfile)) {
$linesraw = file ("$userfile");
$phraselower = array_change_key_case($linesraw, CASE_LOWER);
$lines = array_unique($phraselower);

thanks in advance

try print_r($phraselower) and see if it is printing the right data out first.

ok thanks

Have you checked whether your ISP is using an older version of PHP in which the "array_change_key_case" function is not supported?

[roly]

no print_r($phraselower) gives all as upper and lower case.

duroflex, yes i checked and array_change_key_case is for >= 4.2 and i'm running 4.2.2

Without checking, the Key isn't what you're trying to make lowercase probably. Looks like you're trying to get the Values lowercase.

thanks brujah, yes i think that may be it. it's the value i'm trying to change not the key.

try:

$linesraw = file ("$userfile");
while(list(,$phrase)=each($linesraw)) {
$lines[] = strtolower(trim($phrase));
}

i think the file command above puts data into an array and the strtolower is for strings so that wont work i don't think, but i get the idea.

but you were correct i was trying to change the case of the number and not the word. i have sorted it by using array_flip and all works good now. thanks to all for the help.

btw one last stupid question, if an array was like this:

$input_array = array("FirSt" => 1, "SecOnd" => 2);

is "FirSt" classed as the key or the value of the array

Yes, file() function did put the contents of the file into an array.

But the list(,$phrase)=each($linesraw) line is reading the array and putting the value into $phrase.

The line within the while statement is trimming the $phrase for you (it probably contains linefeed characters at the end of each value) and putting the lowercase value into $lines array for you.

You can run array_unique() on that, and it should work fine.

Yes, that's the key.
