Php preg_split seperates number with comma in two different numbers - php

Question

$line = "Type:Bid, End Time: 12/20/2018 08:10 AM (PST), Price: $8,000,Bids: 14, Age: 0, Description: , Views: 120270, Valuation: $10,75, IsTrue: false";
I need to get this array:
Array ( [0] => Bid [1] => 12/20/2018 08:10 AM (PST) [2] => $8,000 [3] => 14 [4] => 0 [5] => [6] => 120270 [7] => $10,75 [8] => false )

Answer 1

I agree with Andreas about using preg_match_all(), but not with his pattern.
For stability, I recommend consuming the entire string from the beginning.
Match the label and its trailing colon. [^:]+:
Match zero or more spaces. \s*
Forget what you matched so far \K
Lazily match zero or more characters (giving back when possible -- make minimal match). .*?
"Look Ahead" and demand that the matched characters from #4 are immediately followed by a comma, then 1 or more non-comma&non-colon character (the next label), then a colon ,[^,:]+: OR the end of the string $.
Code: (Demo)
$line = "Type:Bid, End Time: 12/20/2018 08:10 AM (PST), Price: $8,000,Bids: 14, Age: 0, Description: , Views: 120270, Valuation: $10,75, IsTrue: false";
var_export(
preg_match_all(
'/[^:]+:\s*\K.*?(?=\s*(?:$|,[^,:]+:))/',
$line,
$out
)
? $out[0] // isolate fullstring matches
: [] // no matches
);
Output:
array (
0 => 'Bid',
1 => '12/20/2018 08:10 AM (PST)',
2 => '$8,000',
3 => '14',
4 => '0',
5 => '',
6 => '120270',
7 => '$10,75',
8 => 'false',
)

Answer 2

New answer according to new request:
I use he same regex for spliting the string and I replace after what is before the colon:
$line = "Type:Bid, End Time: 12/20/2018 08:10 AM (PST), Price: $8,000,Bids: 14, Age: 0, Description: , Views: 120270, Valuation: $10,75, IsTrue: false";
$parts = preg_split("/(?<!\d),|,(?!\d)/", $line);
$result = array();
foreach($parts as $elem) {
$result[] = preg_replace('/^[^:]+:\h*/', '', $elem);
}
print_r ($result);
Output:
Array
(
[0] => Bid
[1] => 12/20/2018 08:10 AM (PST)
[2] => $8,000
[3] => 14
[4] => 0
[5] =>
[6] => 120270
[7] => $10,75
[8] => false
)

Answer 3

I'd use preg_match instead.
Here the pattern looks for digit(s) comma digit(s) or just digit(s) or a word and a comma.
I append a comma to the string to make the regex simpler.
$line = "TRUE,59,m,10,500";
preg_match_all("/(\d+,\d+|\d+|\w+),/", $line . ",", $match);
var_dump($match);

Even with a different order of the items this code will still produce a correct output: https://3v4l.org/SRJOf

Answer 4

much bettter idea:
$parts=explode(',',$line,4); //explode has a limit you can use in this case 4
same result less code.
I would keep it simple and do this
$line = "TRUE,59,m,10,500";
$parts = preg_split("/,/", $line);
//print_r ($parts);
$parts[3]=$parts[3].','.$parts[4]; //create a new part 3 from 3 and 4
//$parts[3].=','.$parts[4]; //alternative syntax to the above
unset($parts[4]);//remove old part 4
print_r ($parts);
i would also just use explode(), rather than a regular expression.
