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

<"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。
