(PHP ActiveX) ITIDA Create Canonical JSON

See more Egypt ITIDA Examples

Demonstrates creating the canonical (ITIDA) version of a JSON document. The document in the example is the one at https://sdk.invoicing.eta.gov.eg/files/one-doc.json

Note: This example requires Chilkat v9.5.0.92 or greater.

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// Note: This example requires Chilkat v9.5.0.92 or greater.
// (In v9.5.0.92, the "itida" encoding was added to StringBuilder's Encode method.)
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.StringBuilder')
$sb = new COM("Chilkat.StringBuilder");

// This is the file at https://sdk.invoicing.eta.gov.eg/files/one-doc.json
$success = $sb->LoadFile('qa_data/itida/sdk.invoicing.eta.gov.eg/files/one-doc.json','utf-8');

    exit;
}

// Convert the contents of sb to the ITIDA canonical form.
// Always pass utf-8 for the 2nd arg.
$sb->Encode('itida','utf-8');

$canonical = $sb->getAsString();

print $canonical . "\n";

// Output: 
// "SomeValue""DELIVERY""APPROACH""SomeValue""PACKAGING""SomeValue""DATEVALIDITY""2020-09-28T09:30:10Z"........."TOTALAMOUNT""5191.50""EXTRADISCOUNTAMOUNT""5.00""TOTALITEMSDISCOUNTAMOUNT""14.00"
