How to escape $ on Sublime Text Snippet

Question

I create a snippet for my PHP laravel in SBT3

<snippet>
    <content><![CDATA[
dd("${1}",${1});
]]></content>
    <tabTrigger>dd</tabTrigger>
    <scope>source.php</scope>
</snippet>

When I typed dd

I see this now.

if I type more

notice it's wrong ?

It need have the $ like this

dd("nameofTheVariable",$nameofTheVariable);

How do I modify my snippet to escape the $?

Answer 1

The nameofTheVariable is stored in ${1}, so you'll need to add another $ before it.

Use a backslash (\) to escape it: dd("${1}",\$${1});

<snippet>
    <content><![CDATA[
dd("${1}", \$${1});
]]></content>
    <tabTrigger>dd</tabTrigger>
    <scope>source.php</scope>
</snippet>
