how i can explode string into an array. Acctually i want to translate english language into the braille. First thing i need to do is to get the character one by one from a string,then convert them by mathing the char from value in database and display the braille code using the pic. As example when user enter "abc ef", this will create value separately between each other.
Array
(
[0] => a
[1] => b
[2] => c
[3] =>
[4] => e
[5] => f
)
i tried to do but not get the desired output. This code separated entire string.
$papar = preg_split('/[\s]+/', $data);
print_r($papar);
I'm sorry for simple question,and if you all have an idea how i should do to translate it, feel free to help. :)

Answer 1

If you're using PHP5, str_split will do precisely what you're seeking to accomplish. It splits each character in a string – including spaces – into an individual element, then returns an array of those elements:
$array = str_split("abc ef");
print_r($array);
Outputs the following:
Array
(
[0] => a
[1] => b
[2] => c
[3] =>
[4] => e
[5] => f
)
UPDATE:
The PHP4 solution is to use preg_split. Pass a double forward slash as the matching pattern to delimit the split character-by-character. Then, set the PREG_SPLIT_NO_EMPTY flag to ensure that no empty pieces will be returned at the start and end of the string:
$array = preg_split('//', "abc ef", -1, PREG_SPLIT_NO_EMPTY); // Returns same array as above

Answer 2

PHP has a very simple method of getting the character at a specific index.
To do this, utilize the substring method and pass in the index you are looking for.
How I would approach your problem is
Ensure the string you are converting has at least a size of one
Determine how long the string is
int strlen ( string $string )
Loop over each character and do some operation depending on that character
With a string "abcdef"
$rest = substr("abcdef", -1); // returns "f"
See the substr page for a full example and more information

Answer 3

You can iterate the string itself.
$data = 'something string';
for($ctr = 0; $ctr < strlen($data); $ctr++)
{
if($data{$ctr}):
$kk = mysql_query("select braille_teks from braille where id_huruf = '$data{$ctr}'");
$jj = mysql_fetch_array($kk);
$gambar = $jj['braille_teks'];
?>
<img src="images/<?php echo $gambar;?>">
<?php
else:
echo "&nbsp";
}
