Returns HTML for a link.
This is a wrapper around l() to allow for more flexible link themeing.
Where performance is more important than theme flexibility, Drupal code that outputs a link should call the l() function directly, as #theme 'link' implementations have a measurable performance impact.
$variables: An associative array containing the keys 'text', 'path', and 'options'. See the l() function for information about these variables.
l()
function theme_link($variables) {
return l($variables['text'], $variables['path'], $variables['options']);
}
