Php 如何在数组中查找已找到id的索引

如何在搜索后返回数组的索引值

$sql=mysql_query("SELECT id,userName,email FROM user ORDER BY id ASC");
$myArray=array();
while($row=mysql_fetch_array($sql)){
    $myArray[$row['eMail']]=$row;
}

我收到电子邮件作为获取变量，我需要这样搜索

$search = $_GET["eMail"];

if (isset($myArray[$search])) {
  echo $my_values[$search]; 
  $isEmailStored= 1; // **means that I have but in WHICH INDEX I need to find out that**
}
else {
$isEmailStored=0;
}

此数组搜索有助于您

//example
$array = array(0 => 'blue', 1 => 'red', 2 => 'green', 3 => 'red');

$key = array_search('green', $array); // $key = 2;
$key = array_search('red', $array);   // $key = 1;

//你的代码

if ( array_search($search,$my_values ) {
  echo $my_values[$search]; 
  $isEmailStored= 1; // means that I have but in WHICH INDEX I need to find out that
}

没有用，我用sql代码代替php数组搜索解决了这个问题。谢谢你的帮助。
