I'm not sure if it was implemented any other way.  There was discussions 
on this mailing list several years ago, but I don't know the outcome:

I have used PHP MapScript to apply SLDs on the server side, such as:

*******************************
<?php

// define variables
define( "MAPFILE", "D:/sld-test.map" );
define( "MODULE", "php_mapscript.dll" );

// load the mapscript module
if (!extension_loaded("MapScript")) dl(MODULE);

// open map
$oMap = ms_newMapObj( MAPFILE );

//get layer
$oLayer = $oMap->getLayerByName("country_bounds");

//apply SLD
$oLayer->applySLD('<StyledLayerDescriptor 
version="1.0.0"><NamedLayer><Name>country_bounds</Name><UserStyle><Title>xxx</Title><FeatureTypeStyle><Rule><Filter><PropertyIsEqualTo><PropertyName>NA3DESC</PropertyName><Literal>Africa</Literal></PropertyIsEqualTo></Filter><LineSymbolizer><Geometry><PropertyName>center-line</PropertyName></Geometry><Stroke><CssParameter 
name="stroke">#0000ff</CssParameter><CssParameter 
name="stroke-width">2.0</CssParameter></Stroke></LineSymbolizer></Rule></FeatureTypeStyle></UserStyle></NamedLayer></StyledLayerDescriptor>');

// set image size
$oMap->setsize(400, 300);

// set image format
$oMap->selectoutputformat("png");

// draw map
$oImage = $oMap->draw();

// set header
header("Content-type: image/gif");

// output map
$url = $oImage->saveImage("");

?>
