Building font file via PHP script

For a complete description of use custom fonts in client-side, read the article: Custom fonts (client-side) > via Virtual file system (VFS)

If you don’t want to install gulp and/or just downloaded pdfMake and want to use custom fonts in client-side, you can generate the vfs_fonts.js with an PHP script as well. Put the code below in a file on a server with the font files you want to include in the same directory and view it in a browser. Use parameter “?tofile” in the URL to write the output to “vfs_fonts.js” in the same directory on the server, otherwise it outputs in the browser window for you to copy/paste.

<?php

    $output = "var vfs = {";
    $phpDir = dir('.');
    while (($file = $phpDir->read())!==false) {
        if ($file != '..' && $file!='.' && $file != 'makefont.php' && $file != 'vfs_fonts.js') {
            $output .= '"';
            $output .= $file;
            $output .= '":"';
            $output .= base64_encode(file_get_contents($file));
            $output .= '",';
        }
    }
    $output=substr($output,0,-1);
    $output .= "}";

    $output .= "; var _global = typeof window === 'object' ? window : typeof global === 'object' ? global : typeof self === 'object' ? self : this; if (typeof _global.pdfMake !== 'undefined' && typeof _global.pdfMake.addVirtualFileSystem !== 'undefined') { _global.pdfMake.addVirtualFileSystem(vfs); } if (typeof module !== 'undefined') { module.exports = vfs; }";

    if (isset($_REQUEST['tofile'])) {
        $fh = fopen('vfs_fonts.js', 'w') or die("CAN'T OPEN FILE FOR WRITING");
        fwrite($fh,$output);
        fclose($fh);
        echo 'vjs_fonts.js created';
    } else {
        echo $output;
    }
