总结:
如果$in_txt是顾客输入的文书,日常可以这么输出:
echo ereg_replace(" {2}","  ",nl2br(htmlspecialchars(stripslashes($in_txt))));

}

?>

  幸好,除了大家早已能够不受任何限制使用的可比操作符之外,PHP 还提供了有些逻辑操作符来允许你把条件语句描述集中起来。上边的报表清楚地方统一规范明了这一个:

假设 $delta = 12 并且 $omega = 9

操作符
意义
例子
结果

&&
AND
$delta == $gamma && $delta > $omega
True

   $delta && $omega < $omega
False

||
OR
$delta == $gamma || $delta < $omega
True

   $delta > $gamma || $delta < $omega
False

!
NOT
!$delta
False

< =
低于或等于
$delta < = $omega
False

  好,大家得以用逻辑操作符重写上边例子的代码,你看,下边包车型客车抒发是或不是更简便易行些?


< ?

if ($day == "Thursday" && $time == "12" && $place == "Italy")
            {
            $lunch = "pasta";

前边看到有人发布
然则速度超慢,也至极长
此间给出后生可畏种

不过你将胜过以下麻烦:

$headlines = sizeof($content);

< ?

1 -
当你计划在hello和world之间投入八个(或三个以上)空格,
你使用:
echo "hello world!";
你收获的输出如故二个空格,可能您在行首参与八个空格,
您的空格也将被忽视。

有好些个截取首页新闻的主次,然则并不能够成功。
她们的办事原理无非两种,意气风发种是使用某个网址称得上backend的后端数据库接口,另后生可畏种则是硬声声的基于html代码截取。本程序采纳的是后人。应该说,容错质量相比好。
<?
$open = fopen("", "r"State of Qatar;//网页地址
$read = fread($open, 15000);
fclose($open);
