Extract Array content for PHP variables

Question

I have a Curl statement that invokes a WS. The answer to this WS is saved via:

$reference = var_dump(json_decode($exec, true));

return $reference;

Since I have this in one function, in the other file I read as follows:

$var = ob_get_clean();

This is where I echo and give the result below:

array(4) {
  ["InvoiceIdOut"]=>
  int(945)
  ["FiscalDocumentNumber"]=>
  string(7) "AAAA945"
  ["InvoiceURL"]=>
  string(34) "http://teste.pt/maistestes/AAAA945"
  ["ErrorMessage"]=>
  NULL
}

However, I don’t understand how I can remove the data and store it in variables.

Answer 1

Commando list or extract

PHP has a command called list which makes the association of a tuple of variables to the values of an array. If the array, as in your example is associative (value-key), you can use the command Extract.

Using your example array, if you use the extract:

extract($seu_array);

It will automatically create variables with key names:

$InvoiceIdOut = 879
$FiscalDocumentNumber = "AAAA879"
$InvoiceURL = "http://teste.pt/maistestes/AAAA879"
$ErrorMessage = null

Answer 2

The mistake is where you use the var_dump().

Look at the documentation of var_dump() and you will see that this function does not return any value.

The right thing would be:

$reference = json_decode($exec, true);
var_dump($reference);
return $reference;

Thus the return of json_decode will be stored in the variable $reference instead of being passed on to var_dump and be disposed of.

Answer 3

I don’t know what the name of your array looks like:

    $array= array(
  "InvoiceIdOut"=>879,
  "FiscalDocumentNumber"=>"AAAA879",
  "InvoiceURL"=>"http://teste.pt/maistestes/AAAA879",
  "ErrorMessage"=> NULL
);

One way to access the content would be to inform the name of the array,:

echo $array['InvoiceIdOut'];

Another way would also be using the Extract , that performs the function that Voce wants, of extracting the content and transforms into variables, thus:

 extract($array);
 echo $InvoiceIdOut;

I hope I’ve helped

Answer 4

You can use the function Extract():

Kind of:

<?php
$foo = array(
    "InvoiceIdOut" => 879,
    "FiscalDocumentNumber" => "AAAA879",
    "InvoiceURL" => "http://teste.pt/maistestes/AAAA879",
    "ErrorMessage" => null,
    );
extract($foo);
echo "\$InvoiceIdOut = $InvoiceIdOut</br>\$FiscalDocumentNumber = $FiscalDocumentNumber</br>\$InvoiceURL = $InvoiceURL</br>\$ErrorMessage = $ErrorMessage</br>";
?>
//saida
$InvoiceIdOut= 879 
$FiscalDocumentNumber = AAAA879
$InvoiceURL = http://teste.pt/maistestes/AAAA879
$ErrorMessage = 

Answer 5

Have you tried that?

$array = ["InvoiceIdOut" => 879, "FiscalDocumentNumber"=>"AAAA879","InvoiceURL"=>"http://teste.pt/maistestes/AAAA879", "ErrorMessage"=>NULL]

$invoiceIdOut = $array[0];
$fiscalDocumentNumber = $array[1];
$invoiceURL = $array[2];
$errorMessage = $array[3];

Answer 6

A simple way is to do: $var = $array["valor da chave"].

An example, where $array would be the name of array in your code.

Code:

<?php

$array = array (
  "InvoiceIdOut" => 879,
  "FiscalDocumentNumber" => "AAAA879",
  "InvoiceURL" => "http://teste.pt/maistestes/AAAA879",
  "ErrorMessage" => NULL
);

$InvoiceIdOut = $array["InvoiceIdOut"];
$FiscalDocumentNumber = $array["FiscalDocumentNumber"];
$InvoiceURL = $array["InvoiceURL"];
$ErrorMessage = $array["ErrorMessage"];

echo '<p> InvoiceIdOut: ' . $InvoiceIdOut . '</p>';
echo '<p> FiscalDocumentNumber: ' . $FiscalDocumentNumber . '</p>';
echo '<p> InvoiceURL: ' . $InvoiceURL . '</p>';
echo '<p> ErrorMessage: ' . $ErrorMessage . '</p>';

?>

Exit:

InvoiceIdOut: 879

FiscalDocumentNumber: AAAA879

InvoiceURL: http://teste.pt/maistestes/AAAA879

ErrorMessage: 

Answer 7

I appreciate the help provided by all. I was not really doing echo out of the function but rather the var_dump inside the function.

So I share here the correct form:

Function receiving WS response:

$reference = json_decode($exec, true);
return $reference;

Out of function:

$reference = Business::check(...Variáveis...)

echo $reference['InvoiceIdOut'];
echo $reference['FiscalDocumentNumber'];
echo $reference['InvoiceURL'];

Thanks again for the help.
