php-get data from form through get method - php

Question

test.php?t=xxx,y=sss
This is how the user inputs data to my script.
How can I get this data as an array inside test.php, and remove the commas?

Answer 1

$temp = explode(',', $_GET['t']);
$t = $temp[0];
$y = substr($temp[1],2);
will get you what you want from the url you gave, however #Tudor Constantin has the best solution.
Edit
This will loop through all however many fields you have. They will finish up in $result in the correct order.
$temp = explode(',', $_GET['t']);
foreach($temp as $var){
if(strpos($var, '=')){
$exp = explode('=', $var);
$result[] = $exp[1];
} else $result[] = $var;
}
then var_dump $result gives this result
array
0 => string 'xxx' (length=3)
1 => string 'sss' (length=3)
2 => string 'ttt' (length=3)
3 => string 'uuu' (length=3)
Edit 2
Or you could try this:-
Say URL is "test.php?t=xxx,y=sss,z=ttt,a=uuu"
$temp = explode(',', $_GET['t']);
$key = array_keys($_GET);
$temp = array_reverse($temp);
$result[$key[0]] = array_pop($temp);
array_reverse($temp);
foreach($temp as $var){
$exp = explode('=', $var);
$result[$exp[0]] = $exp[1];
}
Then var_dump($result); will give you:-
array
't' => string 'xxx' (length=3)
'a' => string 'uuu' (length=3)
'z' => string 'ttt' (length=3)
'y' => string 'sss' (length=3)

Answer 2

By accessing $_GET['t'], you will get the value 'xxx,y=sss' - I think you have to change the URL to something like
test.php?t=xxx&y=sss
So you will be able to access $_GET['t'] and get the value 'xxx' and $_GET['y'] having value 'sss'
You could also send all the parameter values to one variable, separated by '|' for example - then split by that char:
URL would be test.php?array=xxx|sss|ddd|rrr and in test.php you will do:
$arr = explode('|', $_GET['array']);
This way in the $arr variable you will have an array of the values sent (no matter how many are there)
