How to intercept Chinese string in cakephp?

I originally thought I would write a helper to intercept Chinese strings, but I didn’t expect that the truncate method is already provided in cakephp’s Text helper class. Below is the prototype of the truncate method.

Quote

truncate
truncate(string $text, int $length=100, array $options)
Cuts a string to the $length and adds a suffix with 'ending' if the text is longer than $length. If 'exact' is passed as false, the truncation will occur after the next word ending. If 'html' is passed as true, html tags will be respected and will not be cut off.

Text->truncate method There are 3 parameters:

$text: the string that needs to be intercepted

$length: the length that needs to be intercepted, the default is to intercept 100 characters

$options: array parameters. ending means adding the ending string to the end of the intercepted string; if exact is false, the word will not be truncated; if html is true, the html tag will not be truncated

The following code demonstrates how to use the tuncate method:

Php generation

echo $this->Text->truncate(   
    'The killer crept forward and tripped on the rug.',   
    22,   
    array(   
        'ending' => '...',   
        'exact' => false   
    )   
);  
echo $this->Text->truncate(
    'The killer crept forward and tripped on the rug.',
    22,
    array(
        'ending' => '...',
        'exact' => false
    )
);

The above code will output The killer crept...
Note: If you are intercepting a Chinese string, it is best to set exact to true, otherwise the Chinese characters will not be truncated
