PHP: Prepend/append string to a variable

Question

so I have been trying to wrap my head around this thing few hours, but nothing seems to work as expected.

for($i = 0 ; $i < count($lines); $i++){
  $currentLine = $lines[$i];
  $search  = array('ø', '', 'ï', 'ò');$replace = array('ř', 'ť', 'ď', 'ň');
  $subject = str_replace($search, $replace, $currentLine);
  $finalLine = '"'.$subject.'",';
  file_put_contents($fileName, $finalLine, FILE_APPEND);
};

The thing is simple, I am iterating over lines in .dic file (it's just list of words, one word at a line), for each word I do some replacing of wrong characters and at the end of all I try to wrap the word in double quotes (single quotes don't work either).

The problem is, that the quotes aren't added correctly, and instead of "someword", i get ","someword

// $currentLine = someword;
echo '"'.$currentLine.'",';

// returns
","someword

I need this to convert .dic file to json so i can use it in javascript game i am making.

Can someone please help? I can't find any similar question, not here, not on google, nothing. I tried single quotes, i tried making the whole thing array

$newline = Array(
  0 => '"',
  1 => $currentLine,
  2 => '",'
)

and then joining the array but with the same result, I am kinda desperate now, so if someone knows what am I doing wrong, please tell me.

This should work, you concatenate the line between quotes, so the output should also be between quotes — Rizier123

And for json - there's json_encode and not the wheels, you're inventing here. — u_mulder

It might be your intent, but you do know that you are appending to ` $finalLine` and then also appending $finalLine to the $fileName file after every loop iteration? — Chris

@Chris oh my bad, I must have left that there from another unsuccessful try. — Vincurekf

Are you appending one line at a time because the .dlc file is very large? — Greg

I can't tell from the code why you are getting that result. But here is an alternative approach that might help.

// Set these outside the loop
$search  = array('ø', '', 'ï', 'ò');
$replace = array('ř', 'ť', 'ď', 'ň');

$subjects = array();

foreach ($lines as $line)
{
    $subject = str_replace($search, $replace, $line);
    $subject = trim($subject); // trim if you want to remove extraneous spaces

    if (!empty($subject)) // Presumably you don't want to add empty lines if there are any
    {
        $subjects[] = $subject;     
    }
}

$allwords = implode(',', $subjects);

file_put_contents($fileName, $allwords, FILE_APPEND);

Essentially, create an array of the words, join them with "," using the implode() library function and then add the whole lot to your file.

Yes that works, but still, i need those words in quotes, because there are some words like "key" "default" "break" and so on, and when i import this file into javascript, it breaks on those words. But thanks, this is still better than what I did. Update: Got it joined with '","', now i just need to add the stating and ending quote. Thanks @Greg.

Sorry, I forgot about the quotes but great that you got them added.
