PHP Java Bridge 语法，用于创建具有静态字段的对象

Question

我想在PHP Java Bridge中实现这个PDFBox示例，但我被困在PDType1Font.HELVETICA_BOLD字段：

如何在 PHP Java Bridge 中创建它：

PDFont font = PDType1Font.HELVETICA_BOLD;

https://pdfbox.apache.org/1.8/cookbook/workingwithfonts.html

// Create a document and add a page to it
PDDocument document = new PDDocument();
PDPage page = new PDPage();
document.addPage( page );
// Create a new font object selecting one of the PDF base fonts
PDFont font = PDType1Font.HELVETICA_BOLD;
// Start a new content stream which will "hold" the to be created content
PDPageContentStream contentStream = new PDPageContentStream(document, page);
// Define a text content stream using the selected font, moving the cursor and drawing the text "Hello World"
contentStream.beginText();
contentStream.setFont( font, 12 );
contentStream.moveTextPositionByAmount( 100, 700 );
contentStream.drawString( "Hello World" );
contentStream.endText();
// Make sure that the content stream is closed:
contentStream.close();
// Save the results and ensure that the document is properly closed:
document.save( "Hello World.pdf");
document.close();

在 PHP Java Bridge 中

<?php require_once("http://localhost:8080/JavaBridge/java/Java.inc");
$PDDocument= new Java("org.apache.pdfbox.pdmodel.PDDocument");
$PDPage= new Java("org.apache.pdfbox.pdmodel.PDPage");
$PDDocument->addPage( $PDPage);
// Start a new content stream which will "hold" the to be created content
$PDPageContentStream= new Java("org.apache.pdfbox.pdmodel.PDPageContentStream",$PDDocument, $PDPage);
$PDFont= new Java("org.apache.pdfbox.pdmodel.font.PDFont");
// !!!!Stuck on the syntax to use a static field?
$PDFont= $PDFont->PDType1Font("HELVETICA");
?>

我错过了字体，字体框的罐子。此外，可在PDFbox网站上下载。

https://pdfbox.apache.org/download.cgi

$CourierFont = Java("org.apache.pdfbox.pdmodel.font.PDType1Font");
$CourierFont = $CourierFont->COURIER;
