ph とはどういう意味ですか?

質問を翻訳

(voice-over): Just ask Shir Singh (ph), a traffic cop who`s been on duty all week, working 12-hour days in the population.

It makes our eyes burn and it`s difficult to breath, he says.

The smog comes every year where the temperature drops, wind speeds fall, and a mix of dangerous pollutants settles over the city.

Nineteen-year-old Kishur (ph) also spends his days on Delhi`s congested roads. He`s a street hawker. For him pollution means watery eyes, but

also a way to make more money.

Me and my friends, we used to sell balloons, he says, but the pollution is so bad that we switched to selling masks. Two days, we got a thousand

pieces. We already sold 700.

But it`s not easy. Kishur works at one of the busiest and most polluted traffic junctions in the city.

By the time I get home, my throat and my eyes hurt. Everything, he says, smells of smoke.

Hm, I think it's related to their name.
This is a transcript from news.

Their names are not English ones so ph could be phonetic, right? Thanks guys.
