这是一个经常用到的功能，如果字符串太长，需要按照指定的长度进行截断，然后在后面加上三个点的省略号
<?php
//if a string is longer than the defined length,
//it will add 3 periods to the end of the string.
//you can change it to what ever you want for example:
//return substr($str,0,$len).'[<a href="read_more.html">Read More</a>]';
function strLength($str,$len){
$lenght = strlen($str);
if($lenght > $len){
return substr($str,0,$len).'...';
}else{
return $str;
}
}
$str = "This is a fairly long string.";
//The fist part is the string, the second part is how long it can be
echo strLength($str,10).'<br>';
echo strLength($str,30);
?>
