Aug 08, 2016 am 09:31 AMFirst deal with the situation where the file really does not exist. The method is to use Apache’s .htaccess definition. The
method is to create a new .htaccess and add: ErrorDocument 404 /404.php (/404. php is a custom 404 page).
2. Set up under the yii framework
When the requested page does not exist, yii will throw a CHttpException exception with the exception code 404. So how does yii handle this type of exception? There are three following Method:
1. Don’t do anything, yii will handle it by itself
When this type of exception is thrown, yii will render the errorxxx.php (error404.php) template file under framework/view/ by default
2. In protected Create a new errorxxx.php under /views/system, Yii will render the file
3. Configure the exception handler
Add the following configuration in the configuration file main.php, set the exception handling controller to site/error
'errorHandler'=>array( // use 'site/error' action to display errors 'errorAction'=>'site/error', ),
Then in Add in SiteController.php, error controller:
public function actionError() { if($error=Yii::app()->errorHandler->error) {print_r($error); if(Yii::app()->request->isAjaxRequest) echo $error['message']; else $this->render('error', $error); } }
Finally add error.php template file under view/site/:
<?php $this->pageTitle=Yii::app()->name . ' - Error'; $this->breadcrumbs=array( 'Error', ); ?> <h2>Error <?php echo $code; ?></h2> <div class="error"> <?php echo CHtml::encode($message); ?> </div>
The above introduces the unified setting of 404 pages for PHP projects (including under the Yii framework), including aspects of the content. I hope it will be helpful to friends who are interested in PHP tutorials.

The method to get the current session ID in PHP is to use the session_id() function, but you must call session_start() to successfully obtain it. 1. Call session_start() to start the session; 2. Use session_id() to read the session ID and output a string similar to abc123def456ghi789; 3. If the return is empty, check whether session_start() is missing, whether the user accesses for the first time, or whether the session is destroyed; 4. The session ID can be used for logging, security verification and cross-request communication, but security needs to be paid attention to. Make sure that the session is correctly enabled and the ID can be obtained successfully.

To extract substrings from PHP strings, you can use the substr() function, which is syntax substr(string$string,int$start,?int$length=null), and if the length is not specified, it will be intercepted to the end; when processing multi-byte characters such as Chinese, you should use the mb_substr() function to avoid garbled code; if you need to intercept the string according to a specific separator, you can use exploit() or combine strpos() and substr() to implement it, such as extracting file name extensions or domain names.

In PHP, the most common method is to split the string into an array using the exploit() function. This function divides the string into multiple parts through the specified delimiter and returns an array. The syntax is exploit(separator, string, limit), where separator is the separator, string is the original string, and limit is an optional parameter to control the maximum number of segments. For example $str="apple,banana,orange";$arr=explode(",",$str); The result is ["apple","bana

JavaScript data types are divided into primitive types and reference types. Primitive types include string, number, boolean, null, undefined, and symbol. The values are immutable and copies are copied when assigning values, so they do not affect each other; reference types such as objects, arrays and functions store memory addresses, and variables pointing to the same object will affect each other. Typeof and instanceof can be used to determine types, but pay attention to the historical issues of typeofnull. Understanding these two types of differences can help write more stable and reliable code.

std::chrono is used in C to process time, including obtaining the current time, measuring execution time, operation time point and duration, and formatting analysis time. 1. Use std::chrono::system_clock::now() to obtain the current time, which can be converted into a readable string, but the system clock may not be monotonous; 2. Use std::chrono::steady_clock to measure the execution time to ensure monotony, and convert it into milliseconds, seconds and other units through duration_cast; 3. Time point (time_point) and duration (duration) can be interoperable, but attention should be paid to unit compatibility and clock epoch (epoch)

In PHP, to pass a session variable to another page, the key is to start the session correctly and use the same $_SESSION key name. 1. Before using session variables for each page, it must be called session_start() and placed in the front of the script; 2. Set session variables such as $_SESSION['username']='JohnDoe' on the first page; 3. After calling session_start() on another page, access the variables through the same key name; 4. Make sure that session_start() is called on each page, avoid outputting content in advance, and check that the session storage path on the server is writable; 5. Use ses
