In the use of the time, you have to generate a summary of the content strip_tags (), of course, you can also add strip_tags () directly to the function, I did not engage, add it myself. Here's the function: Copy Code code as follows: function Cutstr ($string, $length, $charset, $dot) {//character, interception length, character set, end character if (strlen ($string) return $string; } $pre = Chr (1); $end = Chr (1); Protect Special strings $string = str_replace (Array (' ', '

length of the string is smaller than the length to be intercepted, the system returns// Strlen is used to obtain the length of a string. for example, if the string "happy new year" needs to be intercepted with four Chinese characters,// You must know the number of bytes of these four Chinese characters. Otherwise, the returned string may be "happy new year ..."If (strlen ($ string) Return $ string;}// Convert htmlspecialchars from the original string$ Pre = chr (1 );$ End = chr (1 );$ String =

Otherwise, the returned string may be "Happy New Year ..."If (strlen ($ string) Return $ string;}// Convert htmlspecialchars from the original string$ Pre = chr (1 );$ End = chr (1 );$ String = str_replace (array ('', '"', '$ Strcut = ''; // initialize the return value// If it is UTF-8 encoded (this judgment is incomplete, it may be utf8)If (strtolower (CHARSET) = 'utf-8 '){// The initial continuous loop pointer $ n, the last digit $ tn, the num

Php does not support Chinese very well. It is a problem to intercept Chinese and English characters in a string, and garbled characters may occur if the string is not properly processed, next we can take the Chinese character string function and handle it well.

It is a problem to intercept Chinese and English characters in a string, and garbled characters may occur if the string is not properly processed, next we can take the Chinese character string funct

Use php to intercept a specified length. PHP language: the code used to copy string based on Chinese characters is as follows: functioncutstr ($ string, $ length, $ dot ...) {if (strlen ($ string) $ length) {return $ string ;}$ prechr (1); PHP language: trim strings based on Chinese characters The code is as follows: Function cutstr ($ string, $ length, $ dot = '...'){If (strlen ($ string) Return $ string;}$ Pre = chr (1 );$ End = chr (1 );$ String = str_replace (array ('', '"', '$ Strcut = ''

what I used to do. Now let's look at the Chinese truncation function. The code is as follows Copy Code function Moocutstr ($string, $length, $dot = ' ... ') {Global $charset;if (strlen ($string) return $string;}$string = Str_replace (' ', ' ' ', ' $strcut = ";if (Strtolower ($charset) = = ' Utf-8 ') {$n = $tn = $noc = 0;while ($n $t = Ord ($string [$n]);if ($t = = 9 | | $t = = 10 | | ($tn = 1; $n + +; $

When using the strip_tags () command, you must add strip_tags () to the function. The following are functions: Copy codeThe Code is as follows: function cutstr ($ string, $ length, $ charset, $ dot) {// character, truncation length, Character Set, and Terminator If (strlen ($ string) Return $ string; } $ Pre = chr (1 ); $ End = chr (1 ); // Protect Special strings $ String = str_replace (array ('', '"', '$ Strcut = ''; If (strtolower ($ charset) = 'utf-8 '){ $ N = $ tn = $
