Sometime back I was getting alot of data via some API and I saved it into a flat file doing a simple var_dump or print_r. Now I am looking to process the data and each line looks like:
" 'middle_initial' => '', 'sid' => '1419843', 'fixed' => 'Y', 'cart_weight' => '0', 'key' => 'ABCD', 'state' => 'XX', 'last_name' => 'MNOP', 'email' => '[email protected]', 'city' => 'London', 'street_address' => 'Sample', 'first_name' => 'Sparsh',"
Now I need to get this data back into an array format. Is there a way I can do that?
What about first exploding the string with the explode() function, using ', ' as a separator :
$str = "'middle_initial' => '', 'sid' => '1419843', 'fixed' => 'Y', 'cart_weight' => '0', 'key' => 'ABCD', 'state' => 'XX', 'last_name' => 'MNOP', 'email' => '[email protected]', 'city' => 'London', 'street_address' => 'Sample', 'first_name' => 'Sparsh',";
$items = explode(', ', $str);
var_dump($items);
Which would get you an array looking like this :
array
0 => string ''middle_initial' => ''' (length=22)
1 => string ''sid' => '1419843'' (length=18)
2 => string ''fixed' => 'Y'' (length=14)
3 => string ''cart_weight' => '0'' (length=20)
...
And, then, iterate over that list, matching for each item each side of the =>, and using the first side of => as the key of your resulting data, and the second as the value :
$result = array();
foreach ($items as $item) {
if (preg_match("/'(.*?)' => '(.*?)'/", $item, $matches)) {
$result[ $matches[1] ] = $matches[2];
}
}
var_dump($result);
Which would get you :
array
'middle_initial' => string '' (length=0)
'sid' => string '1419843' (length=7)
'fixed' => string 'Y' (length=1)
'cart_weight' => string '0' (length=1)
...
But, seriously, you should not store data in such an awful format : print_r() is made to display data, for debugging purposes -- not to store it an re-load it later !
If you want to store data to a text file, use serialize() or json_encode(), which can both be restored using unserialize() or json_decode(), respectively.
