Examples
Example #1 ReflectionFunction::__construct() example
<?php
/**
* A simple counter
*
* @return int
*/
function counter1()
{
static $c = 0;
return ++$c;
}
/**
* Another simple counter
*
* @return int
*/
$counter2 = function()
{
static $d = 0;
return ++$d;
};
function dumpReflectionFunction($func)
{
// Print out basic information
printf(
"\n\n===> The %s function '%s'\n".
" declared in %s\n".
" lines %d to %d\n",
$func->isInternal() ? 'internal' : 'user-defined',
$func->getName(),
$func->getFileName(),
$func->getStartLine(),
$func->getEndline()
);
// Print documentation comment
printf("---> Documentation:\n %s\n", var_export($func->getDocComment(), 1));
// Print static variables if existant
if ($statics = $func->getStaticVariables())
{
printf("---> Static variables: %s\n", var_export($statics, 1));
}
}
// Create an instance of the ReflectionFunction class
dumpReflectionFunction(new ReflectionFunction('counter1'));
dumpReflectionFunction(new ReflectionFunction($counter2));
?>
The above example will output something similar to:
===> The user-defined function 'counter1'
declared in Z:\reflectcounter.php
lines 7 to 11
---> Documentation:
'/**
* A simple counter
*
* @return int
*/'
---> Static variables: array (
'c' => 0,
)
===> The user-defined function '{closure}'
declared in Z:\reflectcounter.php
lines 18 to 23
---> Documentation:
'/**
* Another simple counter
*
* @return int
*/'
---> Static variables: array (
'd' => 0,
)
