PHP projects uniformly set up 404 pages (including under the yii framework)
PHP projects uniformly set up 404 pages (including under the yii framework)
Aug 08, 2016 am 09:31 AM
First 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.

How to convert a string from one character encoding to another in PHP
Oct 09, 2025 am 03:45 AM
Use the mb_convert_encoding() function to convert a string between different character encodings. Make sure that PHP's MultibyteString extension is enabled. 1. The format of this function is mb_convert_encoding (string, target encoding, source encoding), such as converting ISO-8859-1 to UTF-8; 2. It can be combined with mb_detect_encoding() to detect the source encoding, but the result may be inaccurate; 3. It is often used to convert old encoding data to UTF-8 to adapt to modern applications; 4. The alternative iconv() supports the //TRANSLIT and //IGNORE options, but the cross-platform consistency is poor; 5. Recommended first
How to use the intl extension for internationalization in PHP

How to use the array_reduce function in PHP
Oct 06, 2025 am 03:45 AM
The array_reduce function simplifies an array into a single value by iteratively applying a callback function, and is often used to sum, splice strings, or convert data structures. 1. The syntax is array_reduce($array,$callback,$initial), and $callback receives $carry (cumulative value) and $item (current element). 2. Summarization example: $numbers=[1,2,3,4,5], the result after callback accumulation is 15. 3. String splicing: Use "Fruits:" as the initial value, add elements one by one, and get "Fruits:,apple,banana,cherry&qu
How to parse command line arguments in a PHP script
Oct 03, 2025 am 04:29 AM
Use $argv and $argc to process command line parameters, $argv[0] is the script name, and subsequently it is the incoming value; getopt() supports short and long options parsing, such as -u or --user=value, the colon represents the required value, and the double colon represents the optional value. Combining the two can achieve flexible parameter processing.
