Convert PostgreSQL array to PHP array

Question

I have trouble reading Postgresql arrays in PHP. I have tried explode(), but this breaks arrays containing commas in strings, and str_getcsv() but it's also no good as PostgreSQL doesn't quote the Japanese strings.

Not working:

explode(',', trim($pgArray['key'], '{}'));
str_getcsv( trim($pgArray['key'], '{}') );

Example:

// print_r() on PostgreSQL returned data: Array ( [strings] => {または, "some string without a comma", "a string, with a comma"} )

// Output: Array ( [0] => または [1] => "some string without a comma" [2] => "a string [3] => with a comma" ) 
explode(',', trim($pgArray['strings'], '{}'));

// Output: Array ( [0] => [1] => some string without a comma [2] => a string, with a comma ) 
print_r(str_getcsv( trim($pgArray['strings'], '{}') ));

Answer 1

If you have PostgreSQL 9.2 you can do something like this:

SELECT array_to_json(pg_array_result) AS new_name FROM tbl1;

The result will return the array as JSON

Then on the php side issue:

$array = json_decode($returned_field);

You can also convert back. Here are the JSON functions page
