这里是一个简单使用 tokenizer 的PHP脚本例子,它将读取一个PHP文件,去掉代码中全部注释,然后只打印纯代码
Example #1 Strip comments with the tokenizer
<?php
if (! defined ( 'T_ML_COMMENT' )) {
define ( 'T_ML_COMMENT' , T_COMMENT );
} else {
define ( 'T_DOC_COMMENT' , T_ML_COMMENT );
}
$source = file_get_contents ( 'example.php' );
$tokens = token_get_all ( $source );
foreach ( $tokens as $token ) {
if ( is_string ( $token )) {
// simple 1-character token
echo $token ;
} else {
// token array
list( $id , $text ) = $token ;
switch ( $id ) {
case T_COMMENT :
case T_ML_COMMENT : // we've defined this
case T_DOC_COMMENT : // and this
// no action on comments
break;
default:
// anything else -> output "as is"
echo $text ;
break;
}
}
}
?>
