If you need a literal dollar-sign in your $replacement, simply escape it with a backslash.
<?php
$value = 'value=5';
echo preg_replace('/(\d)/', '$1$1', $value); // Outputs "value=55"
echo preg_replace('/(\d)/', '\$1$1', $value); // Outputs "value=$15"
echo preg_replace('/(\d)/', '\\$1$1', $value); // Also outputs
"value=$15"
?>
