How Can PHP Libraries Help Map Seat Locations from PDF Floor Plans?

Reading PDF Files for Seat Location Mapping with PHP

Seeking ways to retrieve text layers and coordinates from large PDF floor maps, the following solutions are available:

PHP

• FPDF with FPDI: This library enables opening and adding content to PDF files. It likely supports searching for specific text and retrieving its coordinates.
• TCPDF: Another PHP library that allows for PDF manipulation and content search.

Other Languages

• PDF Parser (PHP): A modern library specifically designed for parsing PDF files and extracting text and metadata.

Implementation:

1. Integrate the chosen library into your PHP script.
2. Open the PDF floor map file.
3. Search for text layers containing seat location information using the library's functions.
4. Extract the text content and corresponding coordinates into an appropriate data structure.

Example (FPDF with FPDI):

// Create an FPDF object
$pdf = new FPDF();
// Open the PDF file
$pdf->AddPage();
$pdf->setSourceFile('floor_map.pdf');
// Loop through the pages of the PDF file
for ($i = 1; $i <= $pdf->setSourceFile('floor_map.pdf')->getNumPages(); $i++) {
  // Get the current page
  $page = $pdf->importPage($i);
  // Search for text containing seat location information
  $text = $pdf->getTextFromPage($page);
  // Process the text to extract seat locations and coordinates
}

Note: The exact implementation will vary depending on the chosen library.
