Various parts of the PHP language are represented internally by types like
8

T_SR. PHP outputs identifiers like this one in parse errors, like

<literal>"Parse error: unexpected T_SR, expecting ',' or ';' in script.php on line 10."</literal>

Various parts of the PHP language are represented internally by tokens.
8
+
A code snippet that contains an invalid sequence of tokens may lead to errors like
9
+
<literal>Parse error: syntax error, unexpected token "==", expecting "(" in script.php on line 10."</literal>
10
+
where token <code>==</code> is internally represented by <constant>T_IS_EQUAL</constant>.

You're supposed to know what T_SR means. For everybody who doesn't
13

know that, here is a table with those identifiers, PHP-syntax and
14

references to the appropriate places in the manual.

The following table lists all tokens. They are also available as PHP constants.

All tokens listed below are also defined as PHP constants. Their value is

automatically generated based on PHP's underlying parser infrastructure.
20
+
T_* constants values are automatically generated based on PHP's underlying parser infrastructure.
22
21
This means that the concrete value of a token may change between two PHP
23
-
versions. For example the <constant>T_FILE</constant> constant is
24
-
<literal>365</literal> in PHP 5.3, while the same value refers now to
25
-
<constant>T_TRAIT</constant> in PHP 5.4 and the value of <constant>T_FILE</constant>
26
-
is <literal>369</literal>. This means that your code should never rely directly
22
+
versions.
23
+
This means that your code should never rely directly
27
24
on the original T_* values taken from PHP version X.Y.Z, to provide some compatibility
28
-
across multiple PHP versions. Instead your code should utilize custom values
29
-
(using big numbers like <literal>10000</literal>) and an appropriate strategy that
30
-
will work with both PHP versions and T_* values.

To make use of T_* constants across multiple PHP versions, undefined constants

appropriate strategy that will work with both PHP versions and T_* values.
