Runtime Configuration

The behaviour of these functions is affected by settings in php.ini.

**Iconv Configure Options**
Name	Default	Changeable	Changelog
iconv.input_encoding	""	PHP_INI_ALL	Available since PHP 4.0.5. Deprecated in PHP 5.6.0.
iconv.output_encoding	""	PHP_INI_ALL	Available since PHP 4.0.5. Deprecated in PHP 5.6.0.
iconv.internal_encoding	""	PHP_INI_ALL	Available since PHP 4.0.5. Deprecated in PHP 5.6.0.

Here's a short explanation of the configuration directives.

Warning

Some systems (like IBM AIX) use "ISO8859-1" instead of "ISO-8859-1" so this value has to be used in configuration options and function parameters.

Many people report problems compiling PHP on Leopard due to a libiconv issue.

This may be due to the small C test programme in ./configure.
It calls open_conv with two const * char arguments (correct), but these are NOT valid charsets to iconv. This then breaks ./configure.

AFAIK from the libiconv documentation, the PHP configure call is incorrect: this function expects two valid charset arguments. (You can see a list of valid arguments by running iconv -l).

Changing the call to:

cd = open_conv("UTF-8","ISO-8859-1") 

returns a valid iconv_t number (non-negative), and configure can then continue setting up for your Makefile compile.
