How can I access an array/object?
(6 answers)
Closed 4 months ago.
I'm not understanding why the array:
<? $data = array( 'items[0][type]' => 'screenprint'); ?>
Is not the same as
<? echo $data['items'][0]['type']; ?>
I'm trying to add to the array but can't seem to figure out how?
array( 'items[0][type]' => 'screenprint')
This is an array which has one key which is named "items[0][type]" which has one value. That's not the same as an array which has a key items which has a key 0 which has a key type. PHP doesn't care that the key kinda looks like PHP syntax, it's just one string. What you want is:
$data = array('items' => array(0 => array('type' => 'screenprint')));
I hope it's obvious that that's a very different data structure.
It should be:
$data = [
'items' => [['type' => 'screenprint']]
];
echo $data['items'][0]['type'];

How to convert an array to object in PHP?
(35 answers)
Closed 2 years ago.
Say I have an array like the following:
$arr = array(
'id' => 123,
'title' => 'Example Title',
);
How come I cannot access the values using PHP's object operator (->)? In theory, I should be able to do $arr->title but that doesn't work and I have to access it as $arr['title'] instead.
I've been reading plenty of examples of people using the object operator however it's not returning anything but a null value.
Has something changed in recent versions of PHP or am I misunderstanding the examples given?
this code work 100% fine
$arr = (object) array(
'id' => 123,
'title' => 'Example Title',
);
echo $arr->title;

print an array as code
(4 answers)
Closed 2 years ago.
for very special purpose I need to transform PHP array into PHP code. I will try to explain what I mean in code below:
$a = array('a' => 'abc', 'path' => INCLUDE_DIR.'/file.txt', 'number' => 1234);
$php_code = some_magic_function($a);
echo $php_code; // outputs: "array('a' => 'abc', 'path' => '/path/to/file.txt', 'number' => 1234)"
So it would write back array as PHP code. I can not find any library that would help me with this.
Any ideas or hints ? Thanks in advance.
I think you want to print the array as a string, in the exact format it would be written in your code.
If so, then the var_export() function is what you need, e.g. something like this:
$a = array('a' => 'abc', 'path' => '/file.txt', 'number' => 1234);
$str = var_export($a, true);
echo $str;

Add values to an associative array in PHP
(2 answers)
Closed 7 years ago.
I want to push new data in array which each value of them.
$array = array("menu1" => "101", "menu2" => "201");
array_push($array, "menu3" => "301");
But I got an error syntax.
And if I use like this :
$array = array("menu1" => "101", "menu2" => "201");
array_push($array, "menu3", "301");
result is : Array ( [menu1]=>101 [menu2]=>201 [0]=>menu3 [1]=>301 )
My hope the result is : Array ( [menu1]=>101 [menu2]=>201 [menu3]=>301 )
I want push new [menu3]=>'301' but I dont know how. Please help me, the answer will be appreciate
You can use
$array["menu3"] = "301"
as for array_push
array_push() treats array as a stack, and pushes the passed variables onto the end of array
so for associative arrays is a no match
another suitable function for what you want but it requires an array argument is array_merge
$result = array_merge(array("one" => "1"), array("two" => "2"));

Smarty: How to reference to the associative array index
(4 answers)
Closed 8 years ago.
I have problem with displaying my array in smarty. It looks like this. Declaration of array:
index.php:
$rewrites = array(
'en' => array(
'homepage' => 'homepage'
),
'de' => array(
'homepage' => 'zuhause'
),
);
$smarty->assign('rewrites', $rewrites);
And in template file:
{$rewrites|#print_r}
{$rewrites[de][homepage]}
First line prints whole array like it is, so array is assigned. But second line shows nothing, why? How to do it properly? If I do it like this {$rewrites.de.homepage} it works but I really need to declare my array value like this {$rewrites[de][homepage]} because 'de' comes from other variable, that define current language. My target is {$rewrites[$lang][homepage]} for example.
Use:
{$rewrites[$lang]['homepage']}
You can use also:
{$rewrites.{$lang}.homepage}
Simply try this:
{$rewrites.de.homepage}
you can do is as follows {$rewrites[$lang].homepage}

Getting the key of the only element in a PHP array
(6 answers)
Closed 8 years ago.
How do I get the value of a key of any array item? Like how a foreach loop turns it into $k => $v...except I only want to do that once, so no need for a loop. Do I really need to make a new array that it flips to?
Take this for example.
1 => array(
'street' => 'Street Address ',
'town' => 'Town/City '
),
2 => array(
'state' => 'State '
),
Those are arrays inside a bigger array. And now I tried to do this
array_flip($thatarrayupthere[2]['state'])
What I want to receive from that is "state" because that is the key name. But I'm getting errors.
I'm not exactly sure what you wan't, but if you just want to get the key of the second array in any given array this might help.
$key = key($array[2]);
In your example above you will get "state" in your $key variable.
$key = array_keys($array[2]);
print_r($key);
