<h1>List of Parser Tokens</h1>
<p class="para">
Various parts of the PHP language are represented internally by types like
T_SR. PHP outputs identifiers like this one in parse errors, like
<em>"Parse error: unexpected T_SR, expecting ',' or ';' in script.php on line 10."</em>
</p>
<p class="para">
You're supposed to know what T_SR means. For everybody who doesn't
know that, here is a table with those identifiers, PHP-syntax and
references to the appropriate places in the manual.
</p>
<blockquote class="note"><p><strong class="note">Note</strong>:
<strong>Usage of T_* constants</strong><br />
<p class="para">
All tokens listed below are also defined as PHP constants. Their value is
automatically generated based on PHP's underlying parser infrastructure.
This means that the concrete value of a token may change between two PHP
versions. For example the <strong><code>T_FILE</code></strong> constant is
<em>365</em> in PHP 5.3, while the same value refers now to
<strong><code>T_TRAIT</code></strong> in PHP 5.4 and the value of <strong><code>T_FILE</code></strong>
is <em>369</em>. This means that your code should never rely directly
on the original T_* values taken from PHP version X.Y.Z, to provide some compatibility
across multiple PHP versions. Instead your code should utilize custom values
(using big numbers like <em>10000</em>) and an appropriate strategy that
will work with both PHP versions and T_* values.
