Printing a multi dimensional array in table using For loop
提问by Muhammad Shahzad
I want to Print a multidimensional array in table using For loop only.
This is $myArray
我想仅使用 For 循环在表中打印多维数组。这是$myArray
$myArray = Array(
[0] => Array
(
[0] => 598
[1] => Introducing abc
[2] =>
)
[1] => Array
(
[0] => 596
[1] => Big Things Happening at abc
[2] =>
)
[2] => Array
(
[0] => 595
[1] => Should I send abc?
[2] =>
)
[3] => Array
(
[0] => 586
[1] => Things you need to know about abc :P
[2] =>
)
);
);
update a new array as var_dump($myArray );
将新数组更新为 var_dump($myArray );

There's a tonne of different approaches to this, so why not have some fun with it.
对此有很多不同的方法，那么为什么不从中获得一些乐趣呢。
If you MUST use a for loop
如果您必须使用 for 循环
No idea why you would, unless it's for a school assignment:
不知道你为什么会这样做，除非是为了学校作业：
for($i=0;$i<count($data);$i++) {
echo('<tr>');
echo('<td>' . $data[$i][0] . '</td>');
echo('<td>' . $data[$i][1] . '</td>');
echo('<td>' . $data[$i][2] . '</td>');
echo('</tr>');
}
But then that's kinda stupid directly accessing the ID's, lets use another for loop in the row:
但是，直接访问 ID 有点愚蠢，让我们在行中使用另一个 for 循环：
for($i=0;$i<count($data);$i++) {
echo('<tr>');
for($j=0;$j<count($data[$i]);$j++) {
echo('<td>' . $data[$i][$j] . '</td>');
}
echo('</tr>');
}
Replace it with an equally as boring foreach loop:
用同样无聊的 foreach 循环替换它：
<table>
<?php foreach($items as $row) {
echo('<tr>');
foreach($row as $cell) {
echo('<td>' . $cell . '</td>');
}
echo('</tr>');
} ?>
</table>
Why not implode the array:
为什么不内爆数组：
<table>
<?php foreach($items as $row) {
echo('<tr>');
echo('<td>');
echo(implode('</td><td>', $row);
echo('</td>');
echo('</tr>');
} ?>
</table>
Mix it up, screw the foreach, and go for a walk; and implode stuff along the way:
把它混合起来，搞砸 foreach，然后去散散步；并沿途内爆东西：
<?php
function print_row(&$item) {
echo('<tr>');
echo('<td>');
echo(implode('</td><td>', $item);
echo('</td>');
echo('</tr>');
}
?>
<table>
<?php array_walk($data, 'print_row');?>
</table>
Double walking... OMG
双人行走... OMG
Yeah, it looks a little silly now, but when you grow the table and things get more complex, things are a little better broken out and modularized:
是的，现在看起来有点傻，但是当你增加表格并且事情变得更复杂时，事情会更好地分解和模块化：
<?php
function print_row(&$item) {
echo('<tr>');
array_walk($item, 'print_cell');
echo('</tr>');
}
function print_cell(&$item) {
echo('<td>');
echo($item);
echo('</td>');
}
?>
<table>
<?php array_walk($data, 'print_row');?>
</table>

Use this, which are actually two nested forloops:
使用这个，它实际上是两个嵌套for循环：
print('<table>');
for($i = 0; $i < count($array); $i++) {
print('<tr>');
for($ii = 0; $ii < count($array[$i]); $ii++) {
print("<td>{$array[$i][$ii]}</td>");
}
print('</tr>');
}
print('</table>');

echo '<table>';
for($i=0;$i<count($array);$i++) {
echo '<tr><td>'.$array[$i][0].'</td>';
echo '<tr><td>'.$array[$i][1].'</td>';
echo '<tr><td>'.$array[$i][2].'</td></tr>';
}
echo '</table>';

Do like this
这样做
echo "<table>";
for($i=0;$i<count($your_array);$i++) {
echo "<tr><td>".$your_array[$i][0]."</td>";
echo "<td>".$your_array[$i][1]."</td>";
echo "<td>".$your_array[$i][2]."</td></tr>";
}
echo "</table>";

Do this
做这个
$arr as your array
then
