xdebug.max_nesting_level Type: integer, default value: 256 (the default value for versions before 2.3 is 100) This setting allows the maximum level of nested functions to run before the script stops. xdebug.scream Type: boolean, Default value: 0, starting from Xdebug version>= 2.1 If this value is set to 1, xdebug will display notifications, warnings and errors for statements marked with the @ symbol and will no longer hide them. ​ ​ Related functions: ​ string xdebug_call_file() Returns the name of the file currently executing this function. ​ string xdebug_call_function() Returns the function source name when the current function is called and executed. int xdebug_call_line() Returns the current line number of execution. ​ Example:
Example:

<?<span>php
    </span><span>function</span> fix_string(<span>$a</span><span>)
    {
        </span><span>echo</span> "Called @ ".<span>
            xdebug_call_file()</span>.
            ":".<span>
            xdebug_call_line()</span>.
            " from ".<span>
            xdebug_call_function();
    }

    </span><span>$ret</span> = fix_string(<span>array</span>('Derick'<span>));
</span>?>

<span>//</span><span> Called @ /home/httpd/html/test/xdebug_caller.php:12 from {main}</span>

string xdebug_call_class() Returns the calling class name. ​ void xdebug_disable() Do not display error tracking information. ​ void xdebug_enable() Display error tracking information. ​ string Starting with version 2.1 This function returns all collected error information formatted in table form. The starting point for collecting error information is determined using the function xdebug_start_error_collection(). By default, this function will not clear the error information collection cache. You can set the parameter to true and the cache will be cleared. ​ array xdebug_get_headers() Returns all header information in an array. All header information set by calling the header() function will be returned. bool xdebug_is_enabled() Check whether the debug trace is valid. ​ int
<?<span>php
</span><span>header</span>( "X-Test", "Testing"<span> );
</span><span>setcookie</span>( "TestCookie", "test-value"<span> );
</span><span>var_dump</span><span>( xdebug_get_headers() );
</span>?>

<span>/*</span><span>*
Returns:

array(2) {
  [0]=>
  string(6) "X-Test"
  [1]=>
  string(33) "Set-Cookie: TestCookie=test-value"
}
</span><span>*/</span>
Copy after login
xdebug_memory_usage() Returns the memory usage of the script. Versions compiled before PHP5.2.1 must be accompanied by the --enable-memory-limit parameter to be effective, and versions after this are always valid. ​ int xdebug_peak_memory_usage() Returns the highest value of memory usage. Versions compiled before PHP5.2.1 must be accompanied by the --enable-memory-limit parameter to be effective, and versions after this are always valid. ​ void xdebug_start_error_collection() Since version 2.1 Once this function is executed, PHP will no longer display any notification warnings and error messages. These messages will be stored in a cache and will not stop until xdebug_stop_error_collection() is executed. The error information content in the cache can be obtained through the xdebug_get_collected_errors() function. ​ void xdebug_stop_error_collection() Starting with version 2.1 Contrary to xdebug_start_error_collection(), it stops collecting all notifications, warnings, and error messages.

C++ function parameter type safety check C++ function parameter type safety check Apr 19, 2024 pm 12:00 PM

C++ parameter type safety checking ensures that functions only accept values ​​of expected types through compile-time checks, run-time checks, and static assertions, preventing unexpected behavior and program crashes: Compile-time type checking: The compiler checks type compatibility. Runtime type checking: Use dynamic_cast to check type compatibility, and throw an exception if there is no match. Static assertion: Assert type conditions at compile time.

Advanced usage of reference parameters and pointer parameters in C++ functions Advanced usage of reference parameters and pointer parameters in C++ functions Apr 21, 2024 am 09:39 AM

Reference parameters in C++ functions (essentially variable aliases, modifying the reference modifies the original variable) and pointer parameters (storing the memory address of the original variable, modifying the variable by dereferencing the pointer) have different usages when passing and modifying variables. Reference parameters are often used to modify original variables (especially large structures) to avoid copy overhead when passed to constructors or assignment operators. Pointer parameters are used to flexibly point to memory locations, implement dynamic data structures, or pass null pointers to represent optional parameters.

The open source model wins GPT-4 for the first time! Arena's latest battle report has sparked heated debate, Karpathy: This is the only list I trust The open source model wins GPT-4 for the first time! Arena's latest battle report has sparked heated debate, Karpathy: This is the only list I trust Apr 10, 2024 pm 03:16 PM

An open source model that can beat GPT-4 has appeared! The latest battle report of the large model arena: the 104 billion parameter open source model CommandR+ climbed to 6th place, tying with GPT-4-0314 and surpassing GPT-4-0613. Image This is also the first open-weight model to beat GPT-4 in the large model arena. The large model arena is one of the only test benchmarks that the master Karpathy trusts. Image CommandR+ from AI unicorn Cohere. The co-founder and CEO of this large model startup is none other than Aidan Gomez, the youngest author of Transformer (referred to as the wheat harvester). As soon as this battle report came out, another wave of big model clubs started

Are there any class-like object-oriented features in Golang? Are there any class-like object-oriented features in Golang? Mar 19, 2024 pm 02:51 PM

There is no concept of a class in the traditional sense in Golang (Go language), but it provides a data type called a structure, through which object-oriented features similar to classes can be achieved. In this article, we'll explain how to use structures to implement object-oriented features and provide concrete code examples. Definition and use of structures First, let's take a look at the definition and use of structures. In Golang, structures can be defined through the type keyword and then used where needed. Structures can contain attributes
