您可以使用 ReflectionFunction 类列出所有参数。无需像 Nguyet.Duc 建议的那样解析选定的文件/文件。

示例
<?php
function foo(&$bar, $big, $small = 1) {}
function bar($foo) {}
function noparams() {}
function byrefandopt(&$the = 'one') {}
$functions = get_defined_functions();
$functions_list = array();
foreach ($functions['user'] as $func) {
$f = new ReflectionFunction($func);
$args = array();
foreach ($f->getParameters() as $param) {
$tmparg = '';
if ($param->isPassedByReference()) $tmparg = '&';
if ($param->isOptional()) {
$tmparg = '[' . $tmparg . '$' . $param->getName() . ' = ' . $param->getDefaultValue() . ']';
} else {
$tmparg.= '&' . $param->getName();
}
$args[] = $tmparg;
unset ($tmparg);
}
$functions_list[] = 'function ' . $func . ' ( ' . implode(', ', $args) . ' )' . PHP_EOL;
}
print_r($functions_list);
?>
输出
数组
(
[0] => function foo ( &&bar, &big, [$small = 1] )
[1] => function bar ( &foo )
[2] => function noparams ( )
[3] => function byrefandopt ( [&$the = one] )
)
