如何在循环中获取多个查询

Question

的index.php

textarea值传递给另一个页面，但它只执行一个查询

搜索页面

<?php 
$text = trim($_POST['textarea']);
$textAr = explode("\n", $text);
$textAr = array_filter($textAr, 'trim'); // remove any extra \r characters left behind

foreach ($textAr as $line) {

} 

$count=count($textAr);


for($i=0;$i<$count;$i++)
{   
$cusdet = "SELECT * from `product` WHERE category LIKE '%" .$textAr[$i]. "%'"; 
echo "SELECT * from products where name='$textAr[$i]'<br><br>"; ?>
 <?php
$query =  mysql_query($cusdet) or die(mysql_error()) ;  
while ($row = mysql_fetch_array($query)) { ?> 
<br><b><?php    echo $row['product']; ?></b><br> <?php echo $row['category']; 
} 

 }   
?>

索引页

 <form method="post" action="search.php">
  <div class="form-group">
  <textarea class="form-control" id="textarea" name="textarea" rows="15" placeholder="Eg:Milk Powder"></textarea>
  </div>
  <div class="col-md-8 col-xs-12 col-sm-7" style="background-color:#1b934d;margin-top: -14px;">
  <h3 style="color:white;font-size: 21px;">To start shopping with the shoppinglist.</h3>
  </div>
  </form>

我需要它才能显示
