问题描述
在将函数的返回值访问到while循环中时，我遇到了如何创建离散div的问题，但我希望将div创建在另一个之外，而不是在另一个内部创建。请参阅以下代码：
I am getting problem in how to create discrete divs when accessing the function's returned value into a while loop, but I want that divs to be created one outside the other instead of being created one inside the other. See the below code:
<html>
<head>
<title>sdcsdzc</title>
</head>
<body>
<?php
$j=0;
while($j<=2)
{ $removed=array("http://www.w3schools.com/html/default.asp","http://www.w3schools.com/js/default.asp","http://www.w3schools.com/sql/default.asp");
$data=crawl_page($removed[$j]);
echo "
<div style=' background-color: #E7EFEF;width:84%;border:1px solid #A5BEBE;'>
<div style='background-color: white;border:1px solid #A5BEBE;'>
$data[0]
</div>
</div>";
$j++;
}
function crawl_page($b)
{
$a=fopen($b,"r");
$contents=stream_get_contents($a);
fclose($a);
$contents=strtolower($contents);
$start='<div class="example"';
$start_pos=strpos($contents,$start);
$first_trim=substr($contents,$start_pos);
$stop='</div>';
$stop_pos=strpos($first_trim,$stop);
$second_trim=substr($first_trim,0,$stop_pos);
$out['0'] = $second_trim;
return $out;
}
?>
</body>
</html>
我无法向你发送我输出的图像但是你可以直接在php中运行这个代码并看到div正在另一个内部创建，但我希望它们一个接一个地离散出来。如果有人能做到这一点，请告诉我，这对我很重要!!
I cant send you the image of my output but you can run this code directly in php and see the divs are creating inside the other, but I want them to come out discretely one after the other. If anyone can do this please do tell me, its important for me !!
推荐答案
j = 0;
while（
j=0; while(
j< = 2）
{
j<=2) {
removed = array（ http://www.w3schools.com/html/default.asp， http://www.w3schools.com/js/default.asp， < span class =code-string> http://www.w3schools.com/sql/default.asp）;
removed=array("http://www.w3schools.com/html/default.asp","http://www.w3schools.com/js/default.asp","http://www.w3schools.com/sql/default.asp");
