从文件中提取函数名（带或不带正则表达式） [英] Extracting function names from a file (with or without regular expressions)

问题描述

如何从PHP文件中提取所有函数名称？

How can I extract all function names from a PHP file?

该文件具有许多功能，它们看起来或多或少像下面这样。

The file has many functions that look more or less like the following. Is a regular expression the best way to do it?

public function someFunction(

private function anotherOne(

推荐答案

你可以用正则表达式找到它们：

You could find them with a regular expression:

# The Regular Expression for Function Declarations
$functionFinder = '/function[\s\n]+(\S+)[\s\n]*\(/';
# Init an Array to hold the Function Names
$functionArray = array();
# Load the Content of the PHP File
$fileContents = file_get_contents( 'thefilename.php' );

# Apply the Regular Expression to the PHP File Contents
preg_match_all( $functionFinder , $fileContents , $functionArray );

# If we have a Result, Tidy It Up
if( count( $functionArray )>1 ){
  # Grab Element 1, as it has the Matches
  $functionArray = $functionArray[1];
}
