 PHP : Function Reference : PDF Functions : PDF_fit_textline
rcable
Here is a function I created in order to allow me to do textblocks on pdflib lite. Hope this helps someone else, cause all the stuff I've found on php.net has helped me.
$p is your pdf resource
$text is the string to put in the box
$cols is the number col characters before a carriage return
$xcrd,$ycrd is lower left of first line.
This will accept \n as a newline/carriage return and use it to skip to next line. It is not setup to hyphenate words, but someday I'll build one, or buy the full pdf package. ;)
function text_block($p,$text,$cols,$xcrd,$ycrd)
{
$font_size=12; //font size, used to space lines on y axis
$tmplines = explode("\n",$text);
for($j=0;$j<count($tmplines);$j++)
{
$tmptxt = explode(" ",$tmplines[$j]);
$str="";
for($i=0;$i<count($tmptxt);$i++)
{
if($str=="") $str=sprintf("%s",$tmptxt[$i]);
else $str=sprintf("%s %s",$str,$tmptxt[$i]);
if((strlen($str) + strlen($tmptxt[$i+1])) > $cols)
{
pdf_fit_textline($p,$str,$xcrd,$ycrd,"");
$str="";
$ycrd-=$font_size;
}
}
pdf_fit_textline($p,$str,$xcrd,$ycrd,"");
$ycrd-=$font_size;
}
return $ycrd;
}

A patch to the code below to handle an array bounds error that arises:
<?php
$nextText = "";
if ( ( count( $tmpTxt ) - 1 ) >= ( $i + 1 ) )
{ $nextText = $tmpTxt[ $i+1 ]; }
if ( ( strlen( $str ) + strlen( $nextText ) ) > $cols )
?>
