how can i do the operation for obtaning the total result?
Thank You
Maybe your question is a possible duplicate from calculate-math-expression-from-a-string-using-eval
However
if you need to store this in a variable you can do
$string='((((((4,50*0,86)*52500*1,0016)+3800)/52500)*2,2046)*1,05)';
$response=eval('return '.str_replace(',','.',$string.';'));
print($response);
the output is:
9.14027512736

How to use php serialize() and unserialize()
(10 answers)
Closed 5 years ago.
I have this record in data base row :
a:2:
{
i:2;a:2:{s:6:"amount";d:150;s:11:"description";s:53:"value1";}
i:3;a:2:{s:6:"amount";d:1800;s:11:"description";s:53:"value 2";}
}
Is it Json or What exactly ?
And how can i extract data from it ?
I want to get each amount and description values
It's serialized data. You can use unserialize() to turn it in to an array.

php - deep search array of arrays and return only matching elements

Closed 5 years ago.
I find this quite hard to explain as you can see in the title but let's say this is how my object looks like,
{
"success":true,
"objects":[
{
"name":"Stick",
"value":"wood",
"size":"large"
}...
]
}
Now I'm trying to get all the data where the objects name is Stick, so basically if it's "name" is stick it should return, name, value and size.

How do I turn this:
$keys=array(1,8,27);
Into this?
$array=array();
$array[1][8][27]='Hooray!';
I have an array that I need as the keys of a multidimensional array.
In the example:
I am using 1, 8 and 27.
I think this would work:
$array[$keys[0]][$keys[1]][$keys[2]] = "Hooray!";
Can't even begin to imagine how to go about making it dynamic though.
