How to make alignment on console in php
提问by user519846
I am trying to run a script through command prompt in PHP and trying to show the result in tabular form. But due to different character length of words I am not able to show the result properly align.
我正在尝试通过 PHP 中的命令提示符运行脚本并尝试以表格形式显示结果。但是由于单词的字符长度不同，我无法正确对齐显示结果。

If you don't want (or not allowed for some reason) to use libraries, you can use standard php printf/ sprintffunctions.
如果您不想（或由于某种原因不允许）使用库，您可以使用标准的 php printf/sprintf函数。
The problem with them that if you have values with variable and non-limited width, then you will have to decide if long values will be truncated or break table's layout.
他们的问题是，如果您的值具有可变和非限制宽度，那么您将必须决定是否截断长值或中断表的布局。
First case:
第一种情况：
// fixed width
$mask = "|%5.5s |%-30.30s | x |\n";
printf($mask, 'Num', 'Title');
printf($mask, '1', 'A value that fits the cell');
printf($mask, '2', 'A too long value the end of which will be cut off');
The output is
输出是
| Num |Title | x |
| 1 |A value that fits the cell | x |
| 2 |A too long value the end of wh | x |
Second case:
第二种情况：
// only min-width of cells is set
$mask = "|%5s |%-30s | x |\n";
printf($mask, 'Num', 'Title');
printf($mask, '1', 'A value that fits the cell');
printf($mask, '2', 'A too long value that will brake the table');
And here we get
在这里我们得到
| Num |Title | x |
| 1 |A value that fits the cell | x |
| 2 |A too long value that will brake the table | x |
If neither of that satisfies your needs and you really need a table with flowing width columns, than you have to calculate maximum width of values in each column. But that is how PEAR::Console_Tableexactly works.
如果这两者都不能满足您的需求，并且您确实需要一个具有流动宽度列的表格，那么您必须计算每列中值的最大宽度。但这PEAR::Console_Table正是工作的方式。

You can use PEAR::Console_Table:
您可以使用PEAR::Console_Table：
Console_Tablehelps you to display tabular data on a terminal/shell/console.
Console_Table帮助您在终端/外壳/控制台上显示表格数据。
Example:
例子：
require_once 'Console/Table.php';
$tbl = new Console_Table();
$tbl->setHeaders(array('Language', 'Year'));
$tbl->addRow(array('PHP', 1994));
$tbl->addRow(array('C', 1970));
$tbl->addRow(array('C++', 1983));
echo $tbl->getTable();
Output:
输出：
+----------+------+
| Language | Year |
+----------+------+
| PHP | 1994 |
| C | 1970 |
| C++ | 1983 |
+----------+------+

Your best option is to use the Pear Package Console_Table ( http://pear.php.net/package/Console_Table/).
您最好的选择是使用 Pear 包 Console_Table ( http://pear.php.net/package/Console_Table/)。
To use - on a console you need to install the pear package, running:
要使用 - 在控制台上，您需要安装梨包，运行：
pear install Console_Table
this should download the package and install. You can then use a sample script such as:
这应该下载包并安装。然后，您可以使用示例脚本，例如：
require_once 'Console/Table.php';
$tbl = new Console_Table();
$tbl->setHeaders(
array('Language', 'Year')
);
$tbl->addRow(array('PHP', 1994));
$tbl->addRow(array('C', 1970));
$tbl->addRow(array('C++', 1983));
echo $tbl->getTable();

You could try the recent simple PHP library ConsoleTableif you don't want to use the standard PHP functions printf/sprintfor the pear package PEAR::Console_Table.
如果您不想使用标准 PHP 函数printf/ sprintf或梨包PEAR::Console_Table ，您可以尝试最近的简单 PHP 库ConsoleTable。
Example:
例子：
require_once 'ConsoleTable.php';
$table = new LucidFrame\Console\ConsoleTable();
$table
->addHeader('Language')
->addHeader('Year')
->addRow()
->addColumn('PHP')
->addColumn(1994)
->addRow()
->addColumn('C++')
->addColumn(1983)
->addRow()
->addColumn('C')
->addColumn(1970)
->display()
;
Output:
输出：
+----------+------+
| Language | Year |
+----------+------+
| PHP | 1994 |
| C++ | 1983 |
| C | 1970 |
+----------+------+

Too old, but i went trough the same now and used str_pad, just set the lenght as the size of your column and thats it
太旧了，但我现在也使用了 str_pad，只需将长度设置为您的列的大小即可

Just in case someone wants to do that in PHP I posted a gist on Github
以防万一有人想在 PHP 中做到这一点，我在 Github 上发布了一个要点
https://gist.github.com/redestructa/2a7691e7f3ae69ec5161220c99e2d1b3
https://gist.github.com/redestructa/2a7691e7f3ae69ec5161220c99e2d1b3
simply call:
只需调用：
$output = $tablePrinter->printLinesIntoArray($items, ['title', 'chilProp2']);
you may need to adapt the code if you are using a php version older than 7.2
如果您使用的是低于 7.2 的 php 版本，则可能需要修改代码
after that call echo or writeLine depending on your environment.
之后根据您的环境调用 echo 或 writeLine 。
