How to decode_json string without quotes in PHP?-CodePudding

I need to decode the JSON string variable to an associative array. The problem I faced was that the key and value of the JSON string don't have quotes. So I want to add the quotes to each key and value. The JSON string that I have:

$incorrectJsonString = "{
 id: uepwhfkj,
 name: sthfor.test,
 product: SIDO-EOSJGF-DOE_IEO
}";

The output that I want:

$correctJsonString = '{
"id": "uepwhfkj",
 "name": "sthfor.test",
 "product": "SIDO-EOSJGF-DOE_IEO"
}';

At least I need to decode this JSON string :

json_decode($correctJsonString, TRUE);

The is no such thing as a 'incorrect JSON string'. A string is either valid JSON or not.

Here is a quick solution, but I would not recommend to try to transform such a string into valid JSON, there are too many problems which can arise.

The solution is to fix the code which provides what you call 'incorrect JSON string'.

$text = '{
 id: uepwhfkj,
 name: sthfor.test,
 product: SIDO-EOSJGF-DOE_IEO
}';

$lines = preg_split("/\r\n|\n|\r/", $text);
$members = array_slice($lines, 1, count($lines) - 2);

foreach ($members as &$line) {
  $indexOfFirstColon = strrpos($line, ':');
  $member = trim(substr($line, 0, $indexOfFirstColon));
  $element = rtrim(trim(substr($line, $indexOfFirstColon   1)), ',');
  $line = "  \"$member\" : \"$element\"";
}
unset($line);

$json = '{' . "\n" . implode(",\n", $members) . "\n" . '}';

print_r($json);

You can the following regex with substitution

(\w ):\s(.*?)(,|$)

See regex demo and PHP example

You can correct string using preg_replace:

<?php
$incorrectJsonString = "{
 id: uepwhfkj,
 name: sthfor.test,
 product: SIDO-EOSJGF-DOE_IEO
}";

$correctJsonString = preg_replace('/(\S ):\s*([^,\n] )(,?\n?)/m', '"$1": "$2"$3', $incorrectJsonString);

// echo $correctJsonString;

var_dump(json_decode($correctJsonString, true));
