SVG in PHP example #WordPress. It uses the PHP function 'file_get_contents' to output an inline SVG from an SVG image file.

_svg.scss

.logo {
    svg {
        .cls-1{
            fill:none;
            stroke: get-color('primary');
        }
        .cls-2{
            fill: get-color('primary');
        } 
    }
}

functions.php

<?php 
function svg($filename, $folder='svg') {
	$file = "/dist/assets/images/$folder/$filename.svg";
	$file_path = get_stylesheet_directory().$file;
	$file_uri = get_stylesheet_directory_uri().$file;
	if (file_exists ( $file_path )) {
		return file_get_contents($file_uri);
	}
}

svg.php

<!-- Use PHP to place inline SVG from file - expects file '/dist/assets/images/svg/logo.svg' -->
<a href="<?php echo esc_url( home_url( '/' ) ); ?>" rel="home" class="logo"><?php 
	echo svg('logo); 
?><span class="hide"><?php bloginfo( 'name' ); ?></span></a>
