This package has not been officially released yet. Use at your own risk.

This wrapper is PSR-4 autoloading compliant and can be installed via composer. Add the following to your composer.json.

"require": {
  	"markushausammann/prince-php": "dev-master"
}

In the official library, the exePath is injected into the constructor, but that makes automatic injection of the prince service harder. Instead use the respective setter.

$prince = new Prince();
$prince->setExePath('/your/bin/path');

Please note that the default path is /usr/local/bin/prince. So you have the option of just making sure the binary of a symlink is in that location if you're running Prince on Linux.

On Windows, be sure to specify the path to the prince.exe file located within the Engine\bin subfolder of the Prince installation.

There are different combination of sources and end products, the (x)html markup can be provided as string or file and can be returned as file or stream.

public function convertFileToFile($xmlPath, $pdfPath = '', &$messages = array())

Convert an XML or HTML file to a PDF file. Returns true if a PDF file was generated successfully.

`xmlPath`

The filename of the input XML or HTML document.

`pdfPath`

The filename of the output PDF file.

`msgs`

An optional array in which to return error and warning messages. Each message is returned as an array of three strings: the message code (`'err'`,`'wrn'` or`'inf'`), the message location (eg. a filename) and the message text.

`returns`

True if a PDF file was generated successfully, false otherwise.

public function convertMultipleFiles($xmlPaths, $pdfPath = '', &$messages = array())

Convert multiple XML or HTML files to a PDF file. Returns true if a PDF file was generated successfully.

`xmlPaths`

An array of the input XML or HTML documents.

`pdfPath`

The filename of the output PDF file.

`msgs`

An optional array in which to return error and warning messages. Each message is returned as an array of three strings: the message code (`'err'`,`'wrn'` or`'inf'`), the message location (eg. a filename) and the message text.

`returns`

True if a PDF file was generated successfully, false otherwise.

public function convertStringToFile($xmlString, $pdfPath = '', &$messages = array())

Convert an XML or HTML string to a PDF file. Returns true if a PDF file was generated successfully.

`xmlString`

A string containing an XML or HTML document.

`pdfPath`

The filename of the output PDF file.

`msgs`

An optional array in which to return error and warning messages. Each message is returned as an array of three strings: the message code (`'err'`,`'wrn'` or`'inf'`), the message location (eg. a filename) and the message text.

`returns`

True if a PDF file was generated successfully, false otherwise.

public function convertFileToPassthru($xmlPath)

Convert an XML or HTML file to a PDF file, which will be passed through to the output buffer of the current PHP page. Returns true if a PDF file was generated successfully.

Currently there is no mechanism to retrieve error/warning messages when using this convert method. However, thesetLog function can be used to direct messages to an external file.

`xmlPath`

The filename of the input XML or HTML document.

`returns`

True if a PDF file was generated successfully, false otherwise.

Note that to have the browser correctly display the PDF output, the following two lines will be needed before the convert method is called:

header('Content-Type: application/pdf')
header('Content-Disposition: inline; filename="foo.pdf"');`

You may also specify attachment for the Content-Disposition header instead of inline, so that the browser will prompt the user to save the PDF file instead of displaying it.

public function convertMultipleFilesToPassthru($xmlPaths)

Convert multiple XML or HTML files to a PDF file, which will be passed through to the output buffer of the current PHP page. Returns true if a PDF file was generated successfully.

Currently there is no mechanism to retrieve error/warning messages when using this convert method. However, thesetLog function can be used to direct messages to an external file.

`xmlPaths`

An array of the input XML or HTML documents.

`returns`

True if a PDF file was generated successfully, false otherwise.

Note that to have the browser correctly display the PDF output, the following two lines will be needed before the convert method is called:

header('Content-Type: application/pdf')
header('Content-Disposition: inline; filename="foo.pdf"');`

You may also specify attachment for the Content-Disposition header instead of inline, so that the browser will prompt the user to save the PDF file instead of displaying it.

public function convertStringToPassthru($xmlString)

Convert an XML or HTML string to a PDF file, which will be passed through to the output buffer of the current PHP page. Returns true if a PDF file was generated successfully.

Currently there is no mechanism to retrieve error/warning messages when using this convert method. However, thesetLog function can be used to direct messages to an external file.

`xmlString`

header('Content-Type: application/pdf')
header('Content-Disposition: inline; filename="foo.pdf"');`

You may also specify attachment for the Content-Disposition header instead of inline, so that the browser will prompt the user to save the PDF file instead of displaying it.
