php - RegEx - How to Extract Price?

Question

How would I extract the dollar amount from the following string

"some text will go here and more and more and then there will be some price $34.03 but that doesn't mean the string will end"

I want to extract $34.03...also want to extract if there is no cents

"some text will go here and more and more and then there will be some price $34 but that doesn't mean the string will end"

Here I want to extract $34

Answer 1

I'm no regex-guru, but was able to whip up the following with RegExr.

/($[0-9]+(.[0-9]{2})?)/

Matches $35.03 and $35. To accept formats like $35,000.52 you would need to include ,

/($[0-9,]+(.[0-9]{2})?)/

This could likely be improved upon, but from my preliminary tests, it works just fine.
