PDF_continue_text

Shortest way to wordwrap in pdf_continue_text. There is no problem with new lines. Thnx to GTECHNICS.com...

<?
$text = $_POST['texfield']; ; 
$lines = explode("\n",$text); 
pdf_set_text_pos($pdfdoc,$x ,$y); 
foreach($lines as $line){ 
    $foo = $line;
    $foo = wordwrap($foo,122,"|");
    $Arrx = explode("|",$foo);
    $i = 0;
    while ($Arrx[$i] != "") {
       pdf_continue_text($pdfdoc,$Arrx[$i]);
       $i++;
    }
} 
?>

I found no possibility to align a Text right. So I wrote a function:

<?php
function pdf_align_right($string, $chars = 10){
    $string = str_pad($string, $chars, " ", STR_PAD_LEFT);
    // Spaces in PDF-Documents are only the Half of a Normal Letter: So we replace them with 2 Spaces
    $string = preg_replace("/ /", "  ", $string);
    return $string;
}
?>

Note that the 2nd Parameter is NOT the Lenght of the returned String because the Spaces will be replaced with 2 Spaces.

For wrapping text in pdf this is the method that I have been using .

It handles variable font and sizes and also variable widths on the paragraph.

<?php
        $c = $db->row['content']; 

    $color = convert_hexcolor_rgbdec($color_hex);
    pdf_setcolor($pdf, 'both', 'rgb', $color['r'], $color['g'], $color['b']);

    $font = pdf_findfont($pdf, "$fontStyle", "host", 1);
    pdf_setfont($pdf, $font, $s); 

    $par1 = stripslashes($c); 

    $j = 0;
    $n = 0;
    while($j < $pw && $c != "") { 
           $f = substr($par1, $n, 1);
           $fWidth = pdf_stringwidth($pdf, "$f", 1, $s);
           $j = $j + $fWidth; 
           $fWidth = 0;
           $n++;
      }
    $wrap = $n; 
    
    $lead = $s + 2; 
    $paragraph = wordwrap($paragraph, $wrap, "***");
    $parArr = explode("***", $paragraph);

    pdf_show_xy($pdf, "$parArr[0]", $x, $y);
    pdf_set_leading($pdf, $lead); 

    $i = 1;
    while($parArr[$i]) { 
        pdf_continue_text($pdf, "$parArr[$i]"); 
        $i++;
    }
}

// Replace the while loop with this foreach and empty lines
// won't be a problem.
foreach($Arr as $line) {
pdf_continue_text($pdf,$line);
}

This is how I wrap text in a PDF file built from database content...
$foo = mysql_result($results,0,"foo");
$foo = wordwrap($foo,72,"|");
$Arr = explode("|",$foo);
$i = 0;
while ($Arr[$i] != "") {
pdf_continue_text($pdf,$Arr[$i]);
$i++;
}
Someone mentioned to me (and rightfully so) that this may be flawed if you have 2 blank lines, and then more text in the variable. Use it for what you will though, you may find it (or an alteration of it) useful.
