復制代碼 代碼如下:
 
<?php 
class NLP{ 
private static $cmd_path; 
// 不以'/'結尾 
static function set_cmd_path($path){ 
self::$cmd_path = $path; 
} 
private function cmd($str){ 
$descriptorspec = array( 
0 => array("pipe", "r"), 
1 => array("pipe", "w"), 
); 
$cmd = self::$cmd_path . "/ictclas"; 
$process = proc_open($cmd, $descriptorspec, $pipes); 
if (is_resource($process)) { 
$str = iconv('utf-8', 'gbk', $str); 
fwrite($pipes[0], $str); 
$output = stream_get_contents($pipes[1]); 
fclose($pipes[0]); 
fclose($pipes[1]); 
$return_value = proc_close($process); 
} 
/* 
$cmd = "printf '$input' | " . self::$cmd_path . "/ictclas"; 
exec($cmd, $output, $ret); 
$output = join("/n", $output); 
*/ 
$output = trim($output); 
$output = iconv('gbk', 'utf-8', $output); 
return $output; 
} 
/** 
* 進行分詞, 返回詞語列表. 
*/ 
function tokenize($str){ 
$tokens = array(); 
$output = self::cmd($input); 
if($output){ 
$ps = preg_split('//s+/', $output); 
foreach($ps as $p){ 
list($seg, $tag) = explode('/', $p); 
$item = array( 
'seg' => $seg, 
'tag' => $tag, 
); 
$tokens[] = $item; 
} 
} 
return $tokens; 
} 
} 
NLP::set_cmd_path(dirname(__FILE__)); 
?> 
復制代碼 代碼如下:
 
<?php 
require_once('NLP.php'); 
var_dump(NLP::tokenize('Hello, World!')); 
?>
