This article is about how php implements ellipses in strings that are too long. Xiaobian thinks it is quite practical, so share it with everyone for reference. Let's follow Xiaobian and have a look.

Php implementation string is too long to display ellipses method: 1, use strlen() function to determine the length of the string;2, if the length of the string exceeds the specified length, and then use substr() function to replace the excess string with ellipses.

Operating environment: windows 10 system, php 7, thinkpad t480 computer.

In fact, we want to replace the redundant string content with ellipses is very simple, just need to use PHP to provide us with reasonable functions can be. Let's see how this can be done in code.

Code implementation:

/** * php Displays strings of specified length, exceeded by ellipses (...) * @ str string * @ len specified length **/function cutSubstr($str,$len=30){ if (strlen($str)>$len) { $str=substr($str,0,$len) . '... '; } return $str;} Thank you for reading!
