reflection - How to extract start line of a property declaration in PHP? -

with reflection, it's easy start , end line e.g. of method in source file: reflectionfunctionabstract::getfilename(), reflectionfunctionabstract::getstartline(), reflectionfunctionabstract::getendline() provide functionality. however, doesn't seem work properties. what's best way extract @ least start line , file name of property declaration in class definition?

it's not trivial not hard.

you can class property defined in via reflection. , there can filename. have either tokenize file , check @ line property declaration or go on file line line , string matching.

here 1 possible way that:

$reflector      = new reflectionproperty('foo', 'bar'); $declaringclass = $reflector->getdeclaringclass(); $classfile      = new splfileobject($declaringclass->getfilename());  foreach ($classfile $line => $content) {     if (preg_match(         '/             (private|protected|public|var) # match visibility or var             \s                             # followed 1 whitespace             \$bar                          # followed var name $bar         /x',         $content)     ) {         echo $line + 1;     } } 

and here demo show works

obviously, above solution assumes property declared in fashion. assumes have 1 class per file. if cannot sure case, tokenization better option. it's more difficult.
