chr不显示来自CLI请求的ascii扩展符号

编程问答 2022-10-31

问题描述

我从cli和PHP脚本中调用的方式如下：

# PHP test.PHP

PHP脚本内容：

<?PHP
echo chr(201);

这是CLI左上角的方形角

但它显示É字符并应为：

symbol


（很抱歉，我在帖子中找不到该字符。）

frame example bad output

我尝试使用其他方法使其正常运行，但没有任何效果：

<?PHP
echo mb_convert_encoding(chr(201),'UTF-8','ISO-8859-1');

<?PHP
echo utf8_encode(chr(201));

PHP文件为UTF-8，没有BOM。

终端设置：

更新：文本输出：

    'idprocess' => string(11): 'c-cron-0001','idform' => string(11): 'c-cron-0001',]

解决方法

在PHP中使用cp1252的扩展ASCII中，chr(201)是É。

执行以下代码：

<?php
for ($i = 0; $i <= 255; $i++) {
    echo "$i: " . htmlentities(chr($i),ENT_QUOTES,'cp1252') . "<br />";
}

您真正要寻找的是Box Drawing characters，它在Unicode中具有其他值。您可以从Wikipedia复制abd粘贴它，也可以只运行以下脚本以显示具有数字实体的所有字符：

<?php
$mains = [250,251,252,253,254,255,256,257];
$subs = [0,1,2,3,4,5,6,7,8,9,'A','B','C','D','E','F'];
echo '<table>';
foreach ($mains as $main){
    foreach ($subs as $sub){
        $code = $main.$sub;
        echo "
            <tr>
                <td><pre>&amp;#x{$code};</pre> </td>
                <td>&#x{$code};</td>
            </tr>" ;
    }
}
echo '</table>';

HTML        char
-----------------
...
&#x2552;    ╒
&#x2553;    ╓
&#x2554;    ╔
&#x2555;    ╕
&#x2556;    ╖
&#x2557;    ╗
...

因此，我假设您想获得类似的内容（运行代码段）：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>test</title>
    <style>
        .monospace {
            font-family: monospace;
        }
    </style>
</head>
<body>
<div class="monospace">
    &#x2554;&#x2550;&#x2550;&#x2550;&#x2550;&#x2550;&#x2550;&#x2550;&#x2550;&#x2550;&#x2550;&#x2550;&#x2557;<br>
    &#x2551; Some text &#x2551;<br>
    &#x255A;&#x2550;&#x2550;&#x2550;&#x2550;&#x2550;&#x2550;&#x2550;&#x2550;&#x2550;&#x2550;&#x2550;&#x255D;
</div>

</body>
</html>

我很确定您会花很长的时间绘制这些框，我建议您使用一些PP脚本来计算内部文本的长度LOL：D

更新

实际上根据this old article的图纸甚至很有趣：D 

<?php

drawBoxes(
    [
        'Header','Hello,World!','Box drawing is alive after all these years!!!! :D','Lorem ipsum dolor sit amet,consectetur adipiscing elit. Vestibulum arcu.'
    ],true,true
);

function drawBoxes(array $lines,$isFirstLineHeader = false,$wrapInPre = false)
{
    $tl = html_entity_decode('╔',ENT_NOQUOTES,'UTF-8'); // top left corner
    $tr = html_entity_decode('╗','UTF-8'); // top right corner
    $bl = html_entity_decode('╚','UTF-8'); // bottom left corner
    $br = html_entity_decode('╝','UTF-8'); // bottom right corner
    $v = html_entity_decode('║','UTF-8');  // vertical wall
    $h = html_entity_decode('═','UTF-8');  // horizontal wall

    $hs = html_entity_decode('─','UTF-8');  // horizontal wall single
    $ls = html_entity_decode('╟','UTF-8');  // right separator
    $rs = html_entity_decode('╢','UTF-8');  // right separator

    $longest = 0;
    foreach ($lines as $line) {
        $len = strlen($line);
        if ($len > $longest) {
            $longest = $len;
        }
    }
    $preStart = $wrapInPre ? "<pre style='font-family: monospace'>" . PHP_EOL : '';
    $preEnd = $wrapInPre ? PHP_EOL . "</pre>" : '';
    echo $preStart . $tl . str_repeat($h,$longest + 2) . $tr . PHP_EOL;
    $i = 0;
    foreach ($lines as $line) {
        $addEmpty = '';
        $len = strlen($line);
        if ($len < $longest) {
            $addEmpty = str_repeat(' ',$longest - $len);
        }
        echo $v . ' ' . $line . $addEmpty . ' ' . $v;
        if ($isFirstLineHeader && $i == 0) {
            echo PHP_EOL . $ls . str_repeat($hs,$longest + 2) . $rs . PHP_EOL;
        } else {
            echo PHP_EOL;
        }
        $i++;
    }

    echo $bl . str_repeat($h,$longest + 2) . $br . $preEnd;
}

输出 

╔═══════════════════════════════════════════════════════════════════════════╗

如果要以HTML显示，请将drawBoxes()函数$wrapInPre的第二个参数设置为true，如果是纯文本，则将false设置为第二个参数。
