Hello im learning php here and i have a question about blockchain.info's wallet api.

so from my understanding network propagation is the amount of nodes a transaction hits before being confirmed.


Im using blockchain.info's wallet api and when a transaction has not had a confirmation yet, blockchain.info shows network propagation in the form of a percentage for any given unconfirmed transaction on their website.


How can i programmatically get this percentage for an unconfirmed transaction using php?..
 
Thanks in advance,
