本文實例講述了php按單詞截取字符串的方法。分享給大家供大家參考。具體分析如下:
這裡指定字符串和單詞數量進行截取
復制代碼 代碼如下:<?php
function limit_words($string, $word_limit)
{
$words = explode(" ",$string);
return implode(" ",array_splice($words,0,$word_limit));
}
//Example Usage
$content = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.";
echo limit_words($content,20);
?>
希望本文所述對大家的php程序設計有所幫助。
