php export needed

Job ID: 32559507

Budget: $30 – $250 USD

I am looking for php expert to parse scrapped content.

Please apply with php script to convert below using php regex or replace function
$str = '1,2,"$1,613","1,740","1,740"'
=>
$str = '1,2,$1613,1740,1740'

I will pay $5 for the above test and share the scraping content & automation ref.
