Various parts of the PHP language are represented internally by types like T_SR. PHP outputs identifiers like this one in parse errors, like "Parse error: unexpected T_SR, expecting ',' or ';' in script.php on line 10."
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.
Note: Usage of T_* constants
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
T_FILE
constant is 365 in PHP 5.3, while the same value refers now toT_TRAIT
in PHP 5.4 and the value ofT_FILE
is 369. 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 10000) and an appropriate strategy that will work with both PHP versions and T_* values.
