I am a newbie to this array thing as still learning. Need to print this nested array. Pls guide me how to do it as when trying to print it is not recognized.
$args = array(
'pUserId'=>"veenu",
"pPassword" => "somePass",
"pCode" => 381,
"pCity" => "DELHI",
$pIn = array("TypeCode" => 22,"Subtype" => "21"));
The way I am trying to print is below
print_r($args[pIn] -> TypeCode);
Error when trying to print is "Undefined index: pIn" and "Trying to get property of non-object"
1.From what I see, you want to have a key pLn pointing to the nested array. This is how you do it:
"pIn" => array("TypeCode" => 22,"Subtype" => "21")
2.It's a good idea when using keys to enclose them in single quotes:
print_r($args['pIn']['TypeCode']);
Cheers!
It should be
echo $args[$pIn]['TypeCode'];
This is a multi-dimensional array.
It has a parent array and an array with key $pIn
.
You are putting $pIn
as a key, but it is not defined. But if you want to put just pIn
(as string), you don't need to express it in a variable.
What you need is simply
$args = array(
"pUserId" => "veenu",
"pPassword" => "somePass",
"pCode" => 381,
"pCity" => "DELHI",
"pIn" => array(
"TypeCode" => 22,
"Subtype" => "21")
);
As $args
is now a multidimensional array, you will be able to get the TypeCode like this:
echo $args["pIn"]["TypeCode"];
As you have it written, you are assigning an array to the variable $pIn and including it in $args but not as an index. Your array as defined looks like:
array(5) {
["pUserId"]=>
string(5) "veenu"
["pPassword"]=>
string(8) "somePass"
["pCode"]=>
int(381)
["pCity"]=>
string(5) "DELHI"
[0]=>
array(2) {
["TypeCode"]=>
int(22)
["Subtype"]=>
string(2) "21"
}
}
You probably want:
$args = array(
'pUserId'=>"veenu",
"pPassword" => "somePass",
"pCode" => 381,
"pCity" => "DELHI",
"pIn" => array("TypeCode" => 22,"Subtype" => "21"));
print_r($args["pIn"]["TypeCode"]);
Notice how the print_r accesses the element you want.
