Help with indentation and text wraping.

[newbtophp]

Hi, Im working on alittle NFO outputer, but the trouble is long text and indentation is not done accurately (it goes out of place). I want to add indentation (3 spaces before the start and end of a line) and any long text to be broken and proceeded to the next line (\n) (if neccesary) - my code: (refer to the expected output to see how im trying to get it too look like).

 

<?php

$nfo_text = <<<eof
      ###################################################################
      #  default text sample of how it should be                        #                                       #
      {text}
      #                                                                 #
      ###################################################################
eof;

function wrap($text) {
$start_indent = "  ";
$end_indent = "  ";
$start = "#".$start_indent;
$end = $end_indent."#";
return $start.$text.$end;
}

$text = "phpfreaks ftw, somelongtexttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttt hey how are you?";
$nfo_text = str_replace('{text}', wrap($text), $nfo_text);

echo "<pre>";
echo($nfo_text);
echo "</pre>";
?>

 

Output:

 

      ###################################################################
      #  default text sample of how it should be                        #                                       #
      #  phpfreaks ftw, somelongtexttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttt hey how are you?#
      #                                                                 #
      ###################################################################

 

Expected Output:

 

      ###################################################################
      #  default text sample of how it should be                        #                                       #
      #  phpfreaks ftw, somelongtexttttttttttttttttttttttttttttttttttt  #
      #  tttttttttttttttttttttttttt hey how are you?                    #
      #                                                                 #
      ###################################################################

 

Anyone can help me?  :-\

$maximumLength = 70;
echo str_repeat('#', $maximumLength + , "\n",
     '#   ', wordwrap($text, $maximumLength, "   #\n#   ", true), "   #\n",
     str_repeat('#', $maximumLength + ;

Hmm ignace I integrated your code:

 

<?php

$nfo_text = <<<eof
      ###################################################################
      #  default text sample of how it should be                        #                                       #
      {text}
      #                                                                 #
      ###################################################################
eof;

$maximumLength = 70;
function wrap($text) {
global $maximumLength;
return str_repeat('#', $maximumLength + . "\n". '#   '.wordwrap($text, $maximumLength, "   #\n#   ", true). "   #\n". str_repeat('#', $maximumLength + ;
}


$text = "phpfreaks ftw, somelongtexttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttt hey how are you?";
$nfo_text = str_replace('{text}', wrap($text), $nfo_text);

echo "<pre>";
echo($nfo_text);
echo "</pre>";

?>

 

But the output is:

 

      ###################################################################
      #  default text sample of how it should be                        #                                       #
      ##############################################################################
#   phpfreaks ftw,   #
#   somelongtexttttttttttttttttttttttttttttttttttttttttttttttttttttttttttt   #
#   tt hey how are you?   #
##############################################################################
      #                                                                 #
      ###################################################################

Great! works great ignace, however does'nt work with line breaks/new lines:

 

Example Text Scenario:

 

$text = "1. Extract the zip files to a folder on your computer.
2. Follow the instructions in readme.txt";

 

Would brake out of the # border and not proceed to the next line properly.

Yeah, and what do you expect of me now? That I write this for you, for free? I already did more for you then I had to. Either try it yourself or pay me.

lol sorry.

 

I tried myself - always do before posting here, ill retry - but pointers would help.

You should modify the code so that it detects newlines and executes:

 

$line = sprintf("% -{$maximumLineLength}s", $line);
if (function_exists($callback)) {
   $line = $callback($line);
}
$lines .= $line;

Hmm I've tried the following but no luck:

 

function wrapify($text, $maximumLineLength = 70, $callback = '') {
    $lines = explode("\n", $text);
    $words = null;
    foreach($lines as $line) {
    $words .= implode(", ", explode(' ', $line));
    }
    $words = explode(", ", $words);

    $line = '';
    $lines = '';
    foreach ($words as $word) {
        if (strlen($line . $word) > $maximumLineLength) {
            $line = sprintf("% -{$maximumLineLength}s", $line);
            if (function_exists($callback)) {
                $line = $callback($line);
            }
            $lines .= $line;
            $line = '';
        }
        $line .= $word . ' ';
    }
    
    if (!empty($line)) {
        $line = sprintf("% -{$maximumLineLength}s", $line);
        if (function_exists($callback)) {
            $line = $callback($line);
        }
        $lines .= $line;
    }

    return $lines;
}

Here's my input:

 

function wrap($text, $maxLineLength = 70){
$lines = explode("\n", wordwrap_cut($text, $maxLineLength));
$out = '';
foreach($lines as $line){
	$out .= "#   " . str_pad($line, $maxLineLength) . "   #\n";
}
return str_repeat('#', $maxLineLength +  . "\n" . $out . str_repeat('#', $maxLineLength + ;
}

function wordwrap_cut($text, $maxLineLength, $break = "\n"){
$split = str_split($text);
for($i = 0, $n = floor(sizeof($split) / $maxLineLength);$i < $n;++$i){
	if(strpos(substr($text, $i * $maxLineLength, ($i + 1) * $maxLineLength), $break) === false){
		array_splice($split, ($i + 1) * $maxLineLength, 0, $break);
	}
}
return implode('', $split);
}

$text = "1. Extract the zip files to a folder on your computer.\n2. Follow the instructions in readme.txt";
echo wrap($text);

 

Output:

 

##############################################################################
#   1. Extract the zip files to a folder on your computer.                   #
#   2. Follow the instructions in readme.txt                                 #
