过滤数组的结果为每个循环

Question

I have this code to create my array from file:

            <?php
            $servers = array();
            $handle = @fopen("data/data.txt", "r");

            if ($handle) {
                while (($buffer = fgets($handle)) !== false) {
                    $line = explode("|", $buffer);
                    $servers[] = array(
                        "name" => $line[0],
                        "ip" => $line[1],
                        "type" => $line[2],
                    );
                }

                fclose($handle);
            }
            ?>

then i have this code to display the array:

                    <?php           
                foreach ($servers as $name => $servers): ?>
                            <td style="width:340px;">&nbsp;<?php echo $servers['name']; ?></td>
                            <td style="width:240px;"><?php echo $servers['ip']; ?></td>
                        </tr>
                <?php endforeach; ?>

this is the array sample:

Array(
[0] => Array
    (
        [name] => aaa
        [ip] => 123
        [type] => good
    )

[1] => Array
    (
        [name] => bbb
        [ip] => 345
        [type] => good
    )
)

suppose i need to filter the result with array type is good, im trying with this code but it only returns the last array:

                    <?php           
                foreach ($servers as $name => $servers): ?>
                    <?php if($servers['type']=="good"){?>
                            <td style="width:340px;">&nbsp;<?php echo $servers['name']; ?></td>
                            <td style="width:240px;"><?php echo $servers['ip']; ?></td>
                        </tr>
                    <?php } ?>
                <?php endforeach; ?>

The error is in the variable name in foreach loop (use $server instead of $serves as $servers already exists and contains your data)

 <?php foreach ($servers a $server): ?>
           <?php if($server['type']=="good"){?>
                <tr>
                    <td style="width:340px;">&nbsp;<?php echo $server['name']; ?></td>
                    <td style="width:240px;"><?php echo $server['ip']; ?></td>
                </tr>
           <?php } ?>
    <?php endforeach; ?>

Filter the array, then print it

<?php
    //Filter the array
    $goodValues = array_filter($servers, function($e){
        return $e['type'] == "good";
        //Use this to be sure
        //return strtolower($e['type']) == "good";
    });

    //Print the values
    foreach ($goodValues as $value):  ?>
        <tr>
            <td style="width:340px;">&nbsp;<?php echo $value['name']; ?></td>
            <td style="width:240px;"><?php echo $value['ip']; ?></td>
        </tr> 
   <?php endforeach; ?>

As this is just numaric array and you're not using the key anywhere inside the body of the loop, you don't need to use as $key => $value and only as $value will suffice. Also notice the different variable names.

<?php foreach ($servers as $server): ?>
    <?php if($server['type']=="good"){?>
        <tr>
            <td style="width:340px;">&nbsp;<?php echo $server['name']; ?></td>
            <td style="width:240px;"><?php echo $server['ip']; ?></td>
        </tr>
    <?php } ?>
<?php endforeach; ?>
