This function encode array to put string to send by url. It correct from of array, that don't
need to decode it;
<?php
function array_to_string($name,$array)
{
$ret="";
$key_var="";
$val_var="";
foreach ($array as $key=>$value)
{
$key_var="{$name}[{$key}]";
if(is_array($value))
$ret.=array_to_string($key_var,$value);
else
{
$val_var=$value;
$ret.="&".urlencode($key_var)."=".urlencode($val_var);
}
}
return $ret;
}
?>
Test:
<?php
$var3=array("key"=>"value",
"key2"=>"value2",
"key3"=>array("key3_key1"=>"value3",
"key3_key2"=>"value4"),
"key4"=>array("key4_key1"=>"value5",
"key4_key2"=>"value6",
"key4_key3"=>array("key4_key3_key1"=>"value7",
"key4_key3_key2"=>"value8",
"key4_key3_key3"=>"value9",
),
"key4_key4"=>"value10"),
);
var_dump($_GET);
$link=$_SERVER['PHP_SELF']."?".array_to_string("var",$var3);
?><br><a href="<?=$link?>"><?=$link?></a>
After you go link, you see:
array(1) {
["var"]=>
array(4) {
["key"]=>
string(5) "value"
["key2"]=>
string(6) "value2"
["key3"]=>
array(2) {
["key3_key1"]=>
string(6) "value3"
["key3_key2"]=>
string(6) "value4"
}
["key4"]=>
array(4) {
["key4_key1"]=>
string(6) "value5"
["key4_key2"]=>
string(6) "value6"
["key4_key3"]=>
array(3) {
["key4_key3_key1"]=>
string(6) "value7"
["key4_key3_key2"]=>
string(6) "value8"
["key4_key3_key3"]=>
string(6) "value9"
}
["key4_key4"]=>
