(PHP ActiveX) Send UTF-16 on TCP or TLS Socket

See more Socket/SSL/TLS Examples

Demonstrates how to send a string on a connected TCP or SSL/TLS socket such that it is the utf-16 byte representation that is sent.

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.

// This example assumes the Chilkat API to have been previously unlocked.

// Let's say we have an XML file saved in the utf-16 byte representation,
// and we want to send it over the connection using the utf-16 byte representation...

// First the file into a Chilkat StringBuilder.
// Tell the LoadFile method that we are reading utf-16 bytes..
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.StringBuilder')

// Once the text is properly contained in the StringBuilder, we can send the contents in any other charset (windows-1252, utf-16, utf-8, etc.) 
// as long as it make sense (i.e. we obviously can't send Japanese text using a single-byte charset such as Windows-1252).
