在php

Question

我有一个像这样的数组：-

$str = array(
    array(
        'amount' => 1.87,
        'user' => 'hello',
    ),
    array(
        'amount' => 0.9,
        'user' => 'test' ,
    ),
    array(
        'amount' => 9,
        'user' => 'hello',
    ),
    array(
        'amount' => 1.4,
        'user' => 'test1',
    )
);

现在，我想在用户“ hello”拥有的html表中显示这两个金额。我尝试了以下搜索：-

$ac = array_search("hello", $str);
echo $str["$ac"];

但是它不起作用。无论如何，用户'hello'会显示这样的结果：-

1.87
9

以便以后可以在html表中显示。

Answer 1

foreach($str as $new_str){
    if($new_str['user']=="hello"){
        echo $new_str['amount'];
        echo "<br />";
    }
}

Answer 2

您可以使用array_column()

$users = array_column($str,'user'); // get all the user list from array
$search = "hello"; // user you want to search
foreach($users as $key=>$value){ // iterate over user array
  if($value == $search){ // compare user name with search value
    echo $str[$key]['amount'] .PHP_EOL; // if matched print the corresponding amount
  }
}

Answer 3

在这里您可以得到

$ac = array_column($record, ‘Hello’);
Print($ac);

Answer 4

<?php
$str = array(
 array(
'amount' => 1.87,
'user' => 'hello',
 ),
 array(
 'amount' => 0.9,
 'user' => 'test' ,
 ),
 array(
'amount' => 9,
'user' => 'hello',
 ),
 array(
 'amount' => 1.4,
 'user' => 'test1',
)
    );

$key = array_keys(array_column($str, 'user'), 'hello');
foreach($key as $value){
  echo $str[$value]["amount"]."<br/>";
}
?>
