For now, exactly like.
This is what I extracted from your example for it to work ->
$ret = str_replace("\n", '', curl_exec($this->curl_handle));
eval("\$arr = $ret;");
$arr1 = var_export($arr, true);
var_dump($arr);
I would like to convert this to a real array.
Im currently trying this ->
$ret = curl_exec($this->curl_handle);
$str = '$array = $ret;';
this is your problems. its to do with string interpolation.
your exec() call is equivelant to
$array = $ret;
guess what that makes $array?
so it should be:
exec("\$array = $ret;");
which will replace the string $ret into the string to be
exec()'ed. alternatively:
exec('$array = '.$ret.';');
geddit?
gotit
eval($str);
var_dump($ret, $array);
next time paste the actual var_dump output, its easier. :-)
It was in the original email. Just not where you thought it would have
been ;)
Thanks for your help.

[PHP] Eval string to array
Im trying to evaluate a string representation of the output of
var_export(),
as an array.
To make a long story short, Im using curl to fetch another php page,
that uses var_export to echo out php data structures.
The fetched data via curl, is a string. Something like ->
array ( 'foo' => 'bar', )
I would like to convert this to a real array.
Im currently trying this ->
$ret = curl_exec($this->curl_handle);
$str = '$array = $ret;';
eval($str);
var_dump($ret, $array);
The resulting var_dump() shows that my eval'ed data is still a string.
string(27) "array ( 'foo' => 'bar', )" string(27) "array ( 'foo' =>
'bar', )"
What should I be doing to get it as an array ->
array(1) { ["foo"]=> string(3) "bar" }
Thanks for your time.
