php使用wordwrap格式化文本段落的方法_php技巧

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.
