PHP 从字符串中删除新行
要从字符串中删除换行符，代码如下-
示例
<?php
$str = "Demo
text for
reference";
echo nl2br($str);
$str = preg_replace('~[\r\n]+~','', $str);
echo "\n".nl2br($str);
?>输出结果
Demo<br /> <br /> text for <br /> <br /> reference Demo text for reference
示例
现在让我们来看另一个示例-
<?php
$str = "Demo
text";
echo nl2br($str);
$str = str_replace(array("\n", "\r"), '', $str);
echo "\n".nl2br($str);
?>输出结果
Demo<br /> <br /> text Demo text
