PDF_fit_textline()
(PECL pdflib >= 2.0.0)
Place single line of text
说明
PDF_fit_textline(resource $pdfdoc,string $text,float $x,float $y,string $optlist): bool
Places a single line of text on the page, subject to various options.成功时返回TRUE
,或者在失败时返回FALSE
。
The function PDF_fit_textline has an "optlist" argument which you use to pass options. In other words, PDF_fit_textline contains many functions instead of one. A classical code smell. The fact that the optlist argument is a string uglyfies this function by a factor of thousand. Conclusion: when you make functions like PDF_show_boxed deprecated, replace it with a better function instead of doing the opposite.
One point about using the PDF_show_boxed function. It does not support Unicode. So if you need that support you will need to use this function or the text flow functions.
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 ) ?>
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; }
For right now, if you are using PDFlib Lite, you can still use the legacy (depreciated) PDF_show_boxed or $p->show_boxed functions to create a text area. This seems to be a good (if not as full-featured) alternative to the textflow functions, and definitely a whole lot easier than trying to write your own text wrapping/hyphenation solution.
