/**

|
|
19 |
* A PHP_CodeSniffer_File object represents a PHP source file and the tokens
|
|
|
20 |
* associated with it.
|
|
|
21 |
*
|
|
|
22 |
* It provides a means for traversing the token stack, along with
|
|
|
23 |
* other token related operations. If a PHP_CodeSniffer_Sniff finds and error or
|
|
|
24 |
* warning within a PHP_CodeSniffer_File, you can raise an error using the
|
|
|
25 |
* addError() or addWarning() methods.
|
|
|
26 |
*
|
|
|
27 |
* <b>Token Information</b>
|
|
|
28 |
*
|
|
|
29 |
* Each token within the stack contains information about itself:
|
|
|
30 |
*
|
|
|
31 |
* <code>
|
|
|
32 |
* array(
|
|
|
33 |
* 'code' => 301, // the token type code (see token_get_all())
|
|
|
34 |
* 'content' => 'if', // the token content
|
|
|
35 |
* 'type' => 'T_IF', // the token name
|
|
|
36 |
* 'line' => 56, // the line number when the token is located
|
|
|
37 |
* 'column' => 12, // the column in the line where this token
|
|
|
38 |
* // starts (starts from 1)
|
|
|
39 |
* 'level' => 2 // the depth a token is within the scopes open
|
|
|
40 |
* 'conditions' => array( // a list of scope condition token
|
|
|
41 |
* // positions => codes that
|
|
|
42 |
* 2 => 50, // openened the scopes that this token exists
|
|
|
43 |
* 9 => 353, // in (see conditional tokens section below)
|
|
|
44 |
* ),
|
|
|
45 |
* );
|
|
|
46 |
* </code>
|
|
|
47 |
*
|
|
|
48 |
* <b>Conditional Tokens</b>
|
|
|
49 |
*
|
|
|
50 |
* In addition to the standard token fields, conditions contain information to
|
|
|
51 |
* determine where their scope begins and ends:
|
|
|
52 |
*
|
|
|
53 |
* <code>
|
|
|
54 |
* array(
|
|
|
55 |
* 'scope_condition' => 38, // the token position of the condition
|
|
|
56 |
* 'scope_opener' => 41, // the token position that started the scope
|
|
|
57 |
* 'scope_closer' => 70, // the token position that ended the scope
|
|
|
58 |
* );
|
|
|
59 |
* </code>
|
|
|
60 |
*
|
|
|
61 |
* The condition, the scope opener and the scope closer each contain this
|
|
|
62 |
* information.
|
|
|
63 |
*
|
|
|
64 |
* <b>Parenthesis Tokens</b>
|
|
|
65 |
*
|
|
|
66 |
* Each parenthesis token (T_OPEN_PARENTHESIS and T_CLOSE_PARENTHESIS) has a
|
|
|
67 |
* reference to their opening and closing parenthesis, one being itself, the
|
|
|
68 |
* other being its oposite.
|
|
|
69 |
*
|
|
|
70 |
* <code>
|
|
|
71 |
* array(
|
|
|
72 |
* 'parenthesis_opener' => 34,
|
|
|
73 |
* 'parenthesis_closer' => 40,
|
|
|
74 |
* );
|
|
|
75 |
* </code>
|
|
|
76 |
*
|
|
|
77 |
* Some tokens can "own" a set of parethesis. For example a T_FUNCTION token
|
|
|
78 |
* has parenthesis around its argument list. These tokens also have the
|
|
|
79 |
* parenthesis_opener and and parenthesis_closer indicies. Not all parethesis
|
|
|
80 |
* have owners, for example parenthesis used for arithmetic operations and
|
|
|
81 |
* function calls. The parenthesis tokens that have an owner have the following
|
|
|
82 |
* auxilery array indicies.
|
|
|
83 |
*
|
|
|
84 |
* <code>
|
|
|
85 |
* array(
|
|
|
86 |
* 'parenthesis_opener' => 34,
|
|
|
87 |
* 'parenthesis_closer' => 40,
|
|
|
88 |
* 'parenthesis_owner' => 33,
|
|
|
89 |
* );
|
|
|
90 |
* </code>
|
|
|
91 |
*
|
|
|
92 |
* Each token within a set of parenthesis also has an array indicy
|
|
|
93 |
* 'nested_parenthesis' which is an array of the
|
|
|
94 |
* left parenthesis => right parenthesis token positions.
|
|
|
95 |
*
|
|
|
96 |
* <code>
|
|
|
97 |
* 'nested_parentheisis' => array(
|
|
|
98 |
* 12 => 15
|
|
|
99 |
* 11 => 14
|
|
|
100 |
* );
|
|
|
101 |
* </code>
|
|
|
102 |
*
|
|
|
103 |
* <b>Extended Tokens</b>
|
|
|
104 |
*
|
|
|
105 |
* PHP_CodeSniffer extends and augments some of the tokens created by
|
|
|
106 |
* <i>token_get_all()</i>. A full list of these tokens can be seen in the
|
|
|
107 |
* <i>Tokens.php</i> file.
