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.
