Declaring variable inside string - php

Question

I have this kind of string.
'"asdfasdf","123456", this is a message. OK'
What i want to do is declare variables according to the first, second quotation and the rest of the message until the OK...
(note: the length of the string inside the '' is not consistent)
$First = "asdfasdf"
$Second = "123456"
$Message = "this is a message"
is this even possible?
is there something like " "$First","$Second", "$Message" OK " kind of way?
TIA.

Answer 1

Is this a CSV file ?
Doesn't seem to, but if it was you should check out the csv functions of php, specifically str_getcsv.
If not, you should just do an explode by , or ", or any combination you think would be most accurate, and then go through each array item.
$string = '"asdfasdf","123456","this is a message. OK"';
$temp = explode('","',$string);
$array = array();
foreach($temp as $key=>$value){
//do stuff with $value and $key
}

Answer 2

You can use regular expressions, like this:
Code
$raw = '"asdfasdf","123456", this is a message. OK'; // this is your raw text
preg_match('/^"(?P<first>[^"]+)","(?P<second>[^"]+)",\s+(?P<message>.+?) OK/', $raw, $matches); // this looks for the pattern you defined and stores the matches in $matches
print_r($matches); // this just dumps out the array of matching substrings
Output
Array
(
[0] => "asdfasdf","123456", this is a message. OK
[first] => asdfasdf
[1] => asdfasdf
[second] => 123456
[2] => 123456
[message] => this is a message.
[3] => this is a message.
)
You can access the individual substrings as, for example, $matches['first'], $matches['second'], or $matches['message'].
