CSS comes here, click compile to build.
If you usePackagist for installing packages, then you can update yourcomposer.json like so:
{"require":{"leafo/lessphp":"0.4.0"}}The typical flow oflessphp is to create a new instance oflessc,configure it how you like, then tell it to compile something using one built incompile methods.
Thecompile method compiles a string of LESS code to CSS.
<?phprequire"lessc.inc.php";$less=newlessc;echo$less->compile(".block { padding: 3 + 4px }");ThecompileFile method reads and compiles a file. It will either return theresult or write it to the path specified by an optional second argument.
echo$less->compileFile("input.less");ThecompileChecked method is likecompileFile, but it only compiles if the outputfile doesn’t exist or it’s older than the input file:
$less->checkedCompile("input.less","output.css");If there any problem compiling your code, an exception is thrown with a helpful message:
try{$less->compile("invalid LESS } {");}catch(exception$e){echo"fatal error: ".$e->getMessage();}Thelessc object can be configured through an assortment of instance methods.Some possible configuration options includechanging the outputformat,setting variables fromPHP, andcontrolling the preservation ofcomments, writingcustomfunctions and much more. It’s all described inthedocumentation.
