Convert HTML table to text
Don't reinvent the wheel. Table rendering is difficult, rendering tables using only text is even more difficult.To clarify the complexity of a text-based table renderer that offers all the features of HTML, take a look at w3m, which is open source:these 3000 lines of code are there only to display html tables.
Transform HTML to Text
There are textbased browsers that can be used by command line, like lynx. You could fwrite your html table into a file, pass that file into the textbased browser and take its output.
Note: textbased browsers are generally used in a shell, which generally displays in monospace. This remains a prerequisite.
lynx and w3m are both available on Windows and you don't need to "install" them, you just need to have the executables and the permission to run them from PHP.
code example:
<?php$table = '<table><tr><td>foo</td><td>bar</td></tr></table>'; //this contains your table$html = "<html><body>$table</body></html>";//write html file$tmpfname = tempnam(sys_get_temp_dir(), "tblemail");$handle = fopen($tmpfname, "w");fwrite($handle, $html);fclose($handle);$myTextTable = shell_exec("w3m.exe -dump \"$tmpfname\"");unlink($tmpfname);w3m.exe needs to be in your working directory.
(didn't try it)
Render a Text table
If you want a native PHP solution, there's also at least one framework (https://github.com/c9s/CLIFramework) aimed at console applications for PHP which has a table renderer.
It doesn't transform HTML to text, but it helps you build a text formatted table with support for multiline cells (which seems to be the most complicated part).
Using CLIFramework you would need a code like this to render your table:
<?phprequire 'vendor/autoload.php';use CLIFramework\Component\Table\Table;$table = new Table;$table->addRow(array( "test product", "5", "£50.00"));$table->addRow(array( "Project Name: Test Project", "", ""));$table->addRow(array( "Page 1 : 01 New York 1.jpg", "", "£0.00"));$myTextTable = $table->render();The CLIFramework table renderer doesn't seem to support anything similar to "colspan" however.
Here's the documentation for the table component: https://github.com/c9s/CLIFramework/wiki/Using-Table-Component
