(PHP ActiveX) UN/EDIFACT Syntax Level A Encoding/Decoding

Demonstrates the new "eda" encoding that can be used throughout Chilkat starting in v9.5.0.65.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

// Note: Requires Chilkat v9.5.0.65 or greater.

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.StringBuilder')
$sb = new COM("Chilkat.StringBuilder");
$sb->Append('The 5 men of 223rd St');
print $sb->getAsString() . "\n";

// Encode the utf-8 byte representation of the string in the 
// UN/EDIFACT syntax level A character set.
$sb->Encode('eda','utf-8');
print $sb->getAsString() . "\n";

// EDA Output should be: BTME027FCF6CFARFI94JT6.)F(14KJ2U

// Decode back to the original string.
$sb->Decode('eda','utf-8');
print $sb->getAsString() . "\n";
print '----' . "\n";

// The following requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// The "eda" encoding can be used anywhere within Chilkat.
// For example, with the Crypt2 API
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Crypt2')
$crypt = new COM("Chilkat.Crypt2");
