This is how you can convert upper case characters/letters to lower case even if they contain swedish characters.
<?php
function mymodule_stringtolower($string) {
$search = array ('/Å/','/Ä/','/Ö/');
$replace = array ('å','ä','ö');
$string = preg_replace($search, $replace, $string);
$string = strtolower($string);
return $string;
}

function check_utf8($str) {
$len = strlen($str);
for($i = 0; $i < $len; $i++){
$c = ord($str[$i]);
if ($c > 128) {
if (($c > 247)) return false;
elseif ($c > 239) $bytes = 4;
elseif ($c > 223) $bytes = 3;
elseif ($c > 191) $bytes = 2;
else return false;
if (($i + $bytes) > $len) return false;
while ($bytes > 1) {
$i++;
$b = ord($str[$i]);
if ($b < 128 || $b > 191) return false;
<?php
function string_to_ascii($string){
$ascii = NULL;
for ($i = 0; $i < strlen($string); $i++) {
$ascii[] = ord($string[$i]); //to array
//$ascii += ord($string[$i]); //add value up to int limit 65000+
//$ascii .= ord($string[$i]); //long string of numbers
}
return($ascii);
}
?>

This is how you find a whole word by its boundary when the word is starting with åäö. The usual boundary expression can handle if Swedish characters is in the string but not if it starts (or ends) the word. That means that a word like "öknen" can't be found but a word like "behöver" will be found.
<?php
$text = "I öknen behöver man vatten";
$keyword = "öknen";
//$keyword = "behöver";
?>This is the usual boundary expression
This is how you find an exact word in some text string. The "\b" is for finding the words boundary and the "i" is to let the search be case insensitive.
<?php
$matches = array();
$text = "Play poker"; //Some text
$keyword = "Poker";
preg_match("/\b".$keyword."\b/i", $text, $matches, PREG_OFFSET_CAPTURE);
foreach ($matches as $key => $value) {
echo "<br>$key => $value";
}
?>
Array
(
[0] => Array
(
[0] => poker
[1] => 5
)
)This is how you can extract words from a text, clean up a bit and store it in an array. The clean up function removes all characters that do not match; a to Z or A to Z or 0 to 9 or - (hyphen).
Here's how to get the first key, the last key, the first value or the last value of a (hash) array without explicitly copying nor altering the original array:
<?php
$array = array('first'=>'111', 'second'=>'222', 'third'=>'333');
// get the first key: returns 'first'
print array_shift(array_keys($array));
// get the last key: returns 'third'
print array_pop(array_keys($array));
// get the first value: returns '111'
print array_shift(array_values($array));
// get the last value: returns '333'
print array_pop(array_values($array));

You have a Comma Separated Value (CSV) file on the server and want to convert it to a HTML table. This example use the first row as a header.
