PHP数组显示 phpinfo, ini, extensions等信息

1. phpinfo to array

function phpinfo_array($return=false)
{
 	ob_start();
 	phpinfo(-1);
 
 	$pi = preg_replace(
 	array('#^.*(.*).*$#ms', '#PHP License.*$#ms',
	 '#Configuration#',  "#\r?\n#", "#(h1|h2|h3|tr)>#", '# +(?:.*?)" src="(?:.*?)=(.*?)" alt="PHP Logo" />'
	  .'PHP Version (.*?)(?:\n+?)#',
	  '#PHP Credits#',
	  '#(?:.*?)" src="(?:.*?)=(.*?)"(?:.*?)Zend Engine (.*?),(?:.*?)#',
	  "# +#", '##', '##'),
 	array('$1', '', '', '', '$1>' . "\n", 'PHP Configuration'."\n".'
PHP Version
$2
'.
	  "\n".'
PHP Egg
$1
',
	  '
PHP Credits Egg
$1
',
	  '
Zend Engine
$2
' . "\n" .
	  '
Zend Egg
$1
', ' ', '%S%', '%E%'),
 	ob_get_clean());

 	$sections = explode('', strip_tags($pi, '


'));
 	unset($sections[0]);

 	$pi = array();
 	foreach($sections as $section)
 	{
   		$n = substr($section, 0, strpos($section, ''));
   		preg_match_all('#%S%(?:
(.*?))?(?:(.*?))?(?:(.*?))?%E%#',$section, $askapache, PREG_SET_ORDER);
   		foreach($askapache as $m) $pi[$n][$m[1]]=(!isset($m[3])||$m[2]==$m[3])?$m[2]:array_slice($m,2);
 	}

 	return ($return === false) ? print_r($pi) : $pi;
}

phpinfo_array();

2. get_loaded_extensions? and PHP_VERSION

print_r(get_loaded_extensions());  

//print_r(apache_get_modules()); // 一般服务商都会屏蔽掉

print_r(PHP_VERSION);

3.? ini to array

$ini_path = php_ini_loaded_file();
print_r($ini_path); 

$ini = parse_ini_file($ini_path);
print_r($ini);

function parse_ini ( $filepath ) 
{
    $ini = file( $filepath );
    if ( count( $ini ) == 0 ) { return array(); }
    $sections = array();
    $values = array();
    $globals = array();
    $i = 0;
    foreach( $ini as $line ){
        $line = trim( $line );
        // Comments
        if ( $line == '' || $line{0} == ';' ) { continue; }
        // Sections
        if ( $line{0} == '[' ) {
            $sections[] = substr( $line, 1, -1 );
            $i++;
            continue;
        }
        // Key-value pair
        list( $key, $value ) = explode( '=', $line, 2 );
        $key = trim( $key );
        $value = trim( $value );
        if ( $i == 0 ) {
            // Array values
            if ( substr( $line, -1, 2 ) == '[]' ) {
                $globals[ $key ][] = $value;
            } else {
                $globals[ $key ] = $value;
            }
        } else {
            // Array values
            if ( substr( $line, -1, 2 ) == '[]' ) {
                $values[ $i - 1 ][ $key ][] = $value;
            } else {
                $values[ $i - 1 ][ $key ] = $value;
            }
        }
    }
    for( $j=0; $j
