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。
