php使用wordwrap格式化文本段落的方法

本文实例讲述了php使用wordwrap格式化文本段落的方法 。分享给大家供大家参考 。具体分析如下：

wordwrap()函数可以按照指定的固定行长度格式化文本段落，让段落看起来更加整齐

<?php
$string = "TRADING ON MARGIN POSES ADDITIONAL
RISKS AND IS NOT SUITABLE FOR ALL
    INVESTORS.
A COMPLETE LIST OF THE RISKS ASSOCIATED WITH MARGIN TRADING IS
AVAILABLE IN THE MARGIN RISK DISCLOSURE DOCUMENT.";
$string = str_replace("\n", " ", $string);
$string = str_replace("\r", " ", $string);
print(wordwrap($string, 40)."\n");
?>

上面的代码返回如下结果

TRADING ON MARGIN POSES ADDITIONAL
RISKS AND IS NOT SUITABLE FOR ALL
INVESTORS. A COMPLETE LIST OF THE
RISKS ASSOCIATED WITH MARGIN TRADING IS
AVAILABLE IN THE MARGIN RISK DISCLOSURE
DOCUMENT.

希望本文所述对大家的php程序设计有所帮助 。
