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.
