正在处理一些评论Feed。有两个数组arrayone是带注释而arraytwo是自定义值如果在arrayone中存在arraytwo的值，则应该从arrayone

中删除该值

那些在这里

    $arraytwo  = array("cool","lo","love");

   $arrayone = Array

   foreach($arraytwo as $sa)
        {
    foreach($arrayone as $fa)

    $result1 = str_replace($sa,"",$fa);

        }

    }

Answer 1

PHP提供的函数非常适合查看字符串值的每个数组条目，然后根据匹配进行过滤（或搜索）。

它是基于pcre的正则表达式扩展的一部分，并调用preg_grep。

在您的情况下，您选择$arryTwo输入并将其转换为正则表达式模式。然后，通过反转匹配（这意味着您的匹配被删除），此模式用于gre $arrayOne。

$pattern  = sprintf('~(\\Q%s\\E)~', implode('\\E|\\Q', $arrayTwo));
$filtered = preg_grep($pattern, $arrayOne, PREG_GREP_INVERT);

结果是过滤后的数组（demo）：

Array
(
    [0] => Aman Namdev Twinkle::how many coast  
    [3] => Aman Nagar::nice 
    [4] => Aarya Kumar::H  
    [5] => Akash Shah::superb 
    ...

如此示例输出所示，条目1和2被过滤掉。

如果您想通过聊天提供搜索，可以使用相同的功能。正则表达式在字符串方面非常强大，但它们并不总是直截了当所以如果你需要更频繁地处理字符串搜索，请花些时间来了解它们，因为它对你很有价值。

参见：

Wildcards in array search (Oct 2011) - 此Q＆amp; A显示了如何将preg_gep与您自己的模式结合使用，例如SQL LIKE patterns ^MysqlDocs。

Answer 2

试试这个。

$temp=array();
$arrayone= array([0]=>..,. ......, [40]=>...);
foreach($arrayone as $key=>$val) {
   for($i=0;$i<count($arraytwo);$i++) {
      $pos = strpos($val, $arraytwo[$i]);
      if($pos === true) {
        $temp[$key] = $val;
      }
   }
}
$result = array_diff($arrayone,$temp);
print_r($result);

Answer 3

简单foreach

foreach ($arrayone as $key => $value)
{
    foreach ($arraytwo as $keyword)
    {
        if(preg_match('/'.$keyword.'/', $value))
            unset($array[$key]);
    }
}

var_dump($array);

Answer 4

使用预定义函数非常简单.....

<?php $array1 = array("a" => "green", "red", "blue", "red"); 
      $array2 = array("b" => "green", "yellow", "red"); 
      $result = array_diff($array1, $array2);
      print_r($result);
?>

输出：

阵（[1] =＆gt;蓝色）

    I needed to remove the contents of $array1 from $array2 so I tried:

   <?php 
        $diff    = array_diff($members1, $members2);
   ?> 
   WRONG!! A quick swap around and things worked smoothly...
   <?php  
       $diff    = array_diff($members2, $members1); 
  ?> 
  Hope this saves someone a bit of bother
