searching for quoted string

[cybert]

I have a function that runs the dig command to get txt records. It currently prints the entire output of the dig command. All I want to be returned is the text (if any) that is inside quotation marks. I am at my wits end. Still relatively new to PHP. Any suggestions would be appreciated.

Use backticks as described in the manual to execute the external program. Assign the results to a variable. Use regular expressions to extract the desired data. Print the result.

I am running the external program in backticks. I am assigning it to a variable. I cannot figure out the regular expresion to fing a string of possible varying length that begins and ends with doublequotes ("). So I guess my question should have read, "Can anyone tell me what the regular expression would be to find any text in a string where the text is enclosed in doublequotes (")?
