sorry seems to be the hardest Detailed explanation of the use of PHP EOT delimiter
The end identifier must start in the first column of the row. Likewise, identifiers must follow the naming rules for any other tag in PHP: they must only contain alphanumeric underscores, and they must start with an underscore or a non-numeric character.
The above introduces the detailed explanation of the use of sorry seems to be the hardest PHP EOT delimiter, including the content of sorry seems to be the hardest. I hope it will be helpful to friends who are interested in PHP tutorials.

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably, The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
Warning
It is important to point out that the line ending the identifier cannot contain any other characters, except perhaps a semicolon (;). This means in particular that the identifier cannot be indented and there cannot be any spaces or tabs before or after the semicolon. It's also important to realize that the first character before the closing identifier must be a newline character as defined in your operating system. For example, on Macintosh systems it is r.
If you break this rule so that the end identifier is not "clean", it will not be treated as an end identifier and PHP will keep looking for it. Failure to find a suitable closing identifier in this case will result in a syntax error on the last line of the script.
Class members cannot be initialized using delimiter syntax. Use other string syntax instead. Example 11-3. Illegal example
PHP code
class foo {
public $bar = <<
EOT;
}
?>
Delimiter text representation Just like a double-quoted string, except without the double quotes. This means that quotes do not need to be escaped within delimited text, but the escape codes listed above can still be used. Variables are expanded, but the same care must be taken when expressing complex variables in delimited literals as with strings. Example 11-4. Delimiter string example
PHP code
$str = <<
spanning multiple lines
using heredoc syntax.
EOT;
/* More complex example, with variables. */
class foo
{
var $foo;
var $bar;
function foo()
{
$this->foo = 'Foo';
$this->bar = array('Bar1', 'Bar2', 'Bar3');
}
}
$foo = new foo();
$name = 'MyName';
echo <<
Now, I am printing some {$foo->bar[1]}.
This should print a capital 'A': x41
EOT;

Note: Delimiter support was added in PHP 4.
