This article describes how to use the DZX1.5 string truncation function cutstr in php source code analysis. Share it with you for your reference. The specific analysis is as follows:

<? Php/*** function source DZX1.5, file location/source/function/function_core.php */define ('charset', 'utf-8'); function cutstr ($ string, $ length, $ dot = "... ") {if (strlen ($ string) <= $ length) {return $ string;} if (strtolower (CHARSET) =" UTF-8 ") {$ n = $ tn = $ noc = 0; while ($ n <strlen ($ string) {$ t = ord ($ string [$ n]); if ($ t = 9 | $ t = 10 | (32 <= $ t & $ t <= 126) {$ tn = 1; $ n ++; $ noc ++;} elseif (194 <=$ t & $ t <= 223) {$ tn = 2; $ n + = 2; $ noc + = 2;} elseif (224 <= $ t & $ t <= 239) {$ tn = 3; $ n + = 3; $ noc + = 2;} elseif (240 <=$ t & $ t <= 247) {$ tn = 4; $ n + = 4; $ noc + = 2;} elseif (248 <= $ t & $ t <= 251) {$ tn = 5; $ n + = 5; $ noc + = 2;} elseif ($ t = 252 | $ t = 253) {$ tn = 6; $ n + = 6; $ noc + = 2;} else {$ n ++;} if ($ noc >=$ length) {break ;}} if ($ noc> $ length) {$ n-= $ tn;} $ strcut = substr ($ string, 0, $ n) ;}else {for ($ I = 0; $ I <$ length; $ I ++) {$ strcut. = ord ($ string [$ I])> 127? $ String [$ I]. $ string [++ $ I]: $ string [$ I] ;}}$ pos = strrpos ($ strcut, chr (1); if ($ pos! = False) {$ strcut = substr ($ strcut, 0, $ pos);} return $ strcut. $ dot;} $ string = 'Test database ablci102020 @(#)!)! Test labor force ddk'; echo cutstr ($ string, 15);/* End of php */

The running result is as follows:
