What are some common challenges when using PHP scripts for converting LaTeX syntax to images?

One common challenge when using PHP scripts for converting LaTeX syntax to images is ensuring that the necessary LaTeX packages are installed on the server. This can lead to compatibility issues and errors during the conversion process. To solve this, you can use a Docker container with a pre-installed LaTeX distribution to ensure consistent results. 

// Example PHP code snippet using a Docker container for LaTeX conversion
$latexSyntax = "\\LaTeX";
$imagePath = "/path/to/output/image.png";

// Build the Docker command to convert LaTeX syntax to image
$dockerCommand = "docker run --rm -v " . __DIR__ . ":/data danteev/texlive pdflatex -output-directory=/data " . $latexSyntax;

// Execute the Docker command
exec($dockerCommand);

// Convert the generated PDF to PNG image
shell_exec("convert -density 300 " . __DIR__ . "/output.pdf " . $imagePath);

// Clean up the temporary PDF file
unlink(__DIR__ . "/output.pdf");
