java.lang.ObjectPHPTagTypes
public final class PHPTagTypes
Contains tag types related to the PHP server platform.
There is no specific tag type defined for the ASP-style PHP tag as it is recognised using the common server tag type.
The tag types defined in this class are not registered by default.
The register()
method is provided as a convenient way to register them all at once.
Field Summary | |
---|---|
static StartTagType |
PHP_SCRIPT
The tag type given to a script-style PHP start tag ( <script language="php"> ... </script> ). |
static StartTagType |
PHP_SHORT
The tag type given to a short-form PHP tag ( <? ... ?> ). |
static StartTagType |
PHP_STANDARD
The tag type given to a standard PHP tag ( <?php ... ?> ). |

public static final StartTagType PHP_STANDARD
<?php ... ?>
).
Note that the standard PHP processor includes as part of the tag any newline characters directly following the closing delimiter, but PHP tags recognised by this library do not include trailing newlines. They must be removed manually if required.
This library only correctly recognises standard PHP tags that comply with the XML syntax for processing instructions.
Specifically, the tag is terminated by the first occurrence of the closing delimiter
"?>
", even if it occurs within a PHP string expression.
Unfortunately there is no reliable way to determine the end of a PHP tag without the use of a PHP parser.
The following code is an example of a standard PHP tag that is not recognised correctly by this parser
because of the presence of the closing delimiter within a string expression:
<?php echo("<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n"); ?>
This is recognised as the PHP tag: <?php echo("<?xml version=\"1.0\" encoding=\"UTF-8\"?>
followed by the plain text: \n"); ?>

When this tag type is registered, all XML processing instructions are recognised as short-form PHP tags instead.
The comments in the documentation of the PHP_STANDARD
tag type regarding the termination of PHP tags and
trailing newlines are also applicable to this tag type.
