I have this string :
0=&task=rose&duration=1.25&user=15&1=&task=daisy&duration=0.75&user=25&2=&task=orchid&duration=1.15&user=7
I want this array structure :
array(
array( "task" => "rose",
"duration" => 1.25,
"user" => 15
),
array( "task" => "daisy",
"duration" => 0.75,
"user" => 25,
),
array( "task" => "orchid",
"duration" => 1.15,
"user" => 7
)
)
Now parse_url won't work for your case, as it will overwrite the duplicate entries. You have to manually extract and group here.
$str = 'decoded_name=0=&task=rose&duration=1.25&user=15&1=&task=daisy&duration=0.75&user=25&2=&task=orchid&duration=1.15&user=7';
preg_match_all('#(\w+)=([^&=]*)(?:&|$)#', $str, $matches, PREG_SET_ORDER);
$result = array();
$i = 0;
foreach ($matches as $m) {
list(, $key, $value) = $m;
if (!strlen($value)) {
$i = (int)$key;
}
else {
$result[$i][$key] = $value;
}
}
The trick is watching out for the numeric keys (sans value), which separate your groups. The loop will generate following nested array:
[0] => Array
(
[task] => rose
[duration] => 1.25
[user] => 15
)
[1] => Array
(
[task] => daisy
[duration] => 0.75
[user] => 25
)
[2] => Array
(
[task] => orchid
[duration] => 1.15
[user] => 7
)
you can't achieve what you want to using the headers send as $_GET['user'] would be 7 (the previous ones would be overwritten. You would need a query string like so to go down that route...
decoded_name=0=&task[]=rose&duration[]=1.25&user[]=15&1=&task[]=daisy&duration[]=0.75&user[]=25&2=&task[]=orchid&duration[]=1.15&user[]=7
if you had that as your query string it would a simple case of using array_push otherwise you will have to parse the string manually - again using array_push to generate the sub arrays and then push those into the parent.
I'm happy to help!
<?php
$input = 'data[0][task]=rose&data[0][duration]=1.25&data[0][user]=15&' .
'data[1][task]=daisy&data[1][duration]=0.75&data[1][user]=25&' .
'data[2][task]=orchid&data[2][duration]=1.15&data[2][user]=7';
$output = array();
parse_str($input, $output);
print_r($output);

Since reparsing your bad input string would be substantially harder than answering your core question, if you want help with that as well, consider opening a new question for it.
Here is a solution without regular expressions. I 'd feel more comfortable with it.
$str = 'decoded_name=0=&task=rose&duration=1.25&user=15&1=&task=daisy&duration=0.75&user=25&2=&task=orchid&duration=1.15&user=7';
// Get rid of "decoded_name", which we don't need
$str = str_replace('decoded_name=', '', $str);
$arr = explode('&', $str);
array_push($arr, '0='); // Add sentinel value to simplify the loop
$results = array();
$parsing = array();
foreach ($arr as $item) {
// If a new task begins
if (strspn($item, '0123456789') == strlen($item) - 1) {
// Add the current item if there is one
if (!empty($parsing)) {
$results[] = $parsing;
}
// Prepare to parse another item
$parsing = array();
continue;
}
// Add data to the current item
list($key, $value) = explode('=', $item);
$parsing[$key] = $value;
}
strspn line looks pretty interesting. Can you explain what it does / how it works? (Never seen such a construct.)strspn (php.net/manual/en/function.strspn.php) condition does here is check that all of the characters in $item except the last one are digits. This matches 0=, 1=, etc and signals that we have encountered a new result item.$str = "decoded_name=0=&task=rose&duration=1.25&user=15&1=&task=daisy&duration=0.75&user=25&2=&task=orchid&duration=1.15&user=7";
$str = preg_replace("/&\d=/", "", $str);
$str = preg_replace("/&/", "=", $str);
$tmp = preg_split("/=+/", $str);
$length = count($tmp);
for ($i = 2, $j = 0; $i < $length; $i+=6, $j++) {
$arr[$j] = array($tmp[$i] => $tmp[$i + 1], $tmp[$i + 2] => $tmp[$i + 3], $tmp[$i + 4] => $tmp[$i + 5]);
}
print_r($arr);
Try to edit your input / textarea in your form
from name="task" into name="data[task]"
then you will see your data in var_dump($_GET)
