I'm changing the logo of the WordPress link screen. For this I am using PHP to filter the function by swapping the CSS. But since I have several services like this, I need to do it dynamically, that is, use the same code for several sites. Then it will look like this:
function my_f(){
echo '<style type="text/css">
h1 a{background-image:url( php tem que ser aqui "exemplo: function();" )
}
</style>';
}
This is generating a problem because php is seeing this as a string.
