$str = 'answers[0] = "Love it"; answers[1] = "Hate it."; answers[2] = "Doesnt care"; answers[3] = "Like it";'
How can I convert it to an array?

It is not easy to convert it to an array...how can we split this type of strings...?? try to pass this input with just values only..Sherin Jose– Sherin Jose2013-09-26 10:24:35 +00:00Commented Sep 26, 2013 at 10:24

Agreed with other comments. This is a crazy format to be trying to import. If you can get the data in a more sensible format (eg JSON), it would be much easier to work with. Why is the data in this format in the first place? It looks like program code; what language is it written in? Why are you trying to import code from one language into another?Spudley– Spudley2013-09-26 10:56:26 +00:00Commented Sep 26, 2013 at 10:56

$str = 'answers[0] = "Love it"; answers[1] = "Hate it."; answers[2] = "Doesnt care"; answers[3] = "Like it";';
preg_match_all('/"(.*)";/U', $str, $matches);
$arr = $matches[1];
var_dump($arr);

Will work fir sample above, but fail if there are other string literals (or may be HEREDOCS e.t.c.)

Depends whether the OP has any other variants
Use
preg_split
to select just the values and put it in to an array
example:
$keywords = preg_split("/[\s,]+/", $str);
Just change the pattern!
check the documentation: http://php.net/manual/en/function.preg-split.php

$str = 'answers[0] = "Love it"; answers[1] = "Hate it."; answers[2] = "Doesnt care"; answers[3] = "Like it";';
$chunks = explode(';', $str);
for ($aa=0;$aa<count($chunks);$aa++)
{
$chunks1 = explode('=', $chunks[$aa]);
$myArray[]=$chunks1[1];
}

If you can add new lines after the semicolons (;), take a look at the parse_ini_string() function.
$str = str_replace(';', "\n", $str); // <- add them in the source if you can
$array = parse_ini_string($str);

Something like this?
<?php
$str = '$answers[0] = "Love it"; $answers[1] = "Hate it."; $answers[2] = "Doesnt care"; $answers[3] = "Like it";';
eval($str);
print_r($answers);
?>

Don't use
eval() if you don't have to. And there is always another way to achieve what you want to. Also, there is no $ signs in OP example string, so it's not an answer.

eval() is not a good practice..it allows permission to execute codes in the server for the input..that may harm your server.....so try another method ....
$str = 'answers[0] = "Love it"; answers[1] = "Hate it."; answers[2] = "Doesnt care"; answers[3] = "Like it";';
preg_match_all('/"(.*?)"/', $str, $answers);
$answer = $answers[0];
print_r($answer);
