php使用wordwrap格式化文本段落的方法

本文實例講述了php使用wordwrap格式化文本段落的方法。分享給大家供大家參考。具體分析如下：

wordwrap()函數可以按照指定的固定行長度格式化文本段落，讓段落看起來更加整齊

<?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");
?>

上面的代碼返回如下結果

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.

希望本文所述對大家的php程序設計有所幫助。
