Basic Usage Examples

Most of the functions are fairly easy to use. The most difficult part is probably creating your first PDF document. The following example should help to get you started. It is developed for PHP 4 and creates the file hello.pdf with one page. It defines some document info field contents, loads the Helvetica-Bold font and outputs the text "Hello world! (says PHP)".

Example #1 Hello World example from PDFlib distribution for PHP 4

<?php
$p 
PDF_new();

/*  open new PDF file; insert a file name to create the PDF on disk */
if (PDF_begin_document($p"""") == 0) {
    die(
"Error: " PDF_get_errmsg($p));
}

PDF_set_info($p"Creator""hello.php");
PDF_set_info($p"Author""Rainer Schaaf");
PDF_set_info($p"Title""Hello world (PHP)!");

PDF_begin_page_ext($p595842"");

$font PDF_load_font($p"Helvetica-Bold""winansi""");

PDF_setfont($p$font24.0);
PDF_set_text_pos($p50700);
PDF_show($p"Hello world!");
PDF_continue_text($p"(says PHP)");
PDF_end_page_ext($p"");

PDF_end_document($p"");

$buf PDF_get_buffer($p);
$len strlen($buf);

header("Content-type: application/pdf");
header("Content-Length: $len");
header("Content-Disposition: inline; filename=hello.pdf");
print 
$buf;

PDF_delete($p);
?>

The following example comes with the PDFlib distribution for PHP 5. It uses the new exception handling and object encapsulation features available in PHP 5. It creates the file hello.pdf with one page. It defines some document info field contents, loads the Helvetica-Bold font and outputs the text "Hello world! (says PHP)".

Example #2 Hello World example from PDFlib distribution for PHP 5

<?php

try {
    
$p = new PDFlib();

    
/*  open new PDF file; insert a file name to create the PDF on disk */
    
if ($p->begin_document("""") == 0) {
        die(
"Error: " $p->get_errmsg());
    }

    
$p->set_info("Creator""hello.php");
    
$p->set_info("Author""Rainer Schaaf");
    
$p->set_info("Title""Hello world (PHP)!");

    
$p->begin_page_ext(595842"");

    
$font $p->load_font("Helvetica-Bold""winansi""");

    
$p->setfont($font24.0);
    
$p->set_text_pos(50700);
    
$p->show("Hello world!");
    
$p->continue_text("(says PHP)");
    
$p->end_page_ext("");

    
$p->end_document("");

    
$buf $p->get_buffer();
    
$len strlen($buf);

    
header("Content-type: application/pdf");
    
header("Content-Length: $len");
    
header("Content-Disposition: inline; filename=hello.pdf");
    print 
$buf;
}
catch (
PDFlibException $e) {
    die(
"PDFlib exception occurred in hello sample:\n" .
    
"[" $e->get_errnum() . "] " $e->get_apiname() . ": " .
    
$e->get_errmsg() . "\n");
}
catch (
Exception $e) {
    die(
$e);
}
$p 0;
?>
