PHP会破坏字符串，但将引号中的单词作为一个单词来处理

How can I explode the following string:

我如何引爆下面的字符串:

Lorem ipsum "dolor sit amet" consectetur "adipiscing elit" dolor

into

成

array("Lorem", "ipsum", "dolor sit amet", "consectetur", "adipiscing elit", "dolor")

So that the text in quotation is treated as a single word.

所以引文中的文字被当作一个词来处理。

Here's what I have for now:

下面是我现在要讲的:

$mytext = "Lorem ipsum %22dolor sit amet%22 consectetur %22adipiscing elit%22 dolor"
$noquotes = str_replace("%22", "", $mytext");
$newarray = explode(" ", $noquotes);

but my code divides each word into an array. How do I make words inside quotation marks treated as one word?

但是我的代码将每个单词都分割成一个数组。如何使引号内的单词成为一个单词?

You could use a preg_match_all(...):

您可以使用preg_match_all(…):

$text = 'Lorem ipsum "dolor sit amet" consectetur "adipiscing \\"elit" dolor';
preg_match_all('/"(?:\\\\.|[^\\\\"])*"|\S+/', $text, $matches);
print_r($matches);

which will produce:

这将会产生:

Array
(
    [0] => Array
        (
            [0] => Lorem
            [1] => ipsum
            [2] => "dolor sit amet"
            [3] => consectetur
            [4] => "adipiscing \"elit"
            [5] => dolor
        )

)

And as you can see, it also accounts for escaped quotes inside quoted strings.

正如你所看到的，它也解释了引号内的转义引号。

A short explanation:

一个简短的解释:

"           # match the character '"'
(?:         # start non-capture group 1 
  \\        #   match the character '\'
  .         #   match any character except line breaks
  |         #   OR
  [^\\"]    #   match any character except '\' and '"'
)*          # end non-capture group 1 and repeat it zero or more times
"           # match the character '"'
|           # OR
\S+         # match a non-whitespace character: [^\s] and repeat it one or more times

And in case of matching %22 instead of double quotes, you'd do:

如果匹配%22而不是双引号，你应该这样做:

preg_match_all('/%22(?:\\\\.|(?!%22).)*%22|\S+/', $text, $matches);

This would have been much easier with str_getcsv().

使用str_getcsv()会容易得多。

$test = 'Lorem ipsum "dolor sit amet" consectetur "adipiscing elit" dolor';
var_dump(str_getcsv($test, ' '));

Gives you

给你

array(6) {
  [0]=>
  string(5) "Lorem"
  [1]=>
  string(5) "ipsum"
  [2]=>
  string(14) "dolor sit amet"
  [3]=>
  string(11) "consectetur"
  [4]=>
  string(15) "adipiscing elit"
  [5]=>
  string(5) "dolor"
}

#3

You can also try this multiple explode function

你也可以尝试这个多重爆炸函数

function multiexplode ($delimiters,$string)
{

$ready = str_replace($delimiters, $delimiters[0], $string);
$launch = explode($delimiters[0], $ready);
return  $launch;
}

$text = "here is a sample: this text, and this will be exploded. this also | this one too :)";
$exploded = multiexplode(array(",",".","|",":"),$text);

print_r($exploded);

In some situations the little known token_get_all() might prove useful:

在某些情况下，鲜为人知的token_get_all()可能被证明是有用的:

$tokens = token_get_all("<?php $text ?>");
$separator = ' ';
$items = array();
$item = "";
$last = count($tokens) - 1;
foreach($tokens as $index => $token) {
    if($index != 0 && $index != $last) {
        if(count($token) == 3) {
            if($token[0] == T_CONSTANT_ENCAPSED_STRING) {
                $token = substr($token[1], 1, -1);
            } else {
                $token = $token[1];
            }
        }
        if($token == $separator) {
            $items[] = $item;
            $item = "";
        } else {
            $item .= $token;
        }
    }
}

结果:

Array

    [1] => ipsum
    [2] => dolor sit amet
    [3] => consectetur
    [4] => adipiscing elit
    [5] => dolor

I came here with a complex string splitting problem similar to this, but none of the answers here did exactly what I wanted - so I wrote my own.

我带着一个类似的复杂的弦分裂问题来到这里，但是这里没有一个答案能达到我想要的效果——所以我写了我自己的答案。

I am posting it here just in case it is helpful to someone else.

我把它贴在这里，以防对别人有帮助。

This is probably a very slow and inefficient way to do it - but it works for me.

这可能是一种非常缓慢而低效的方法，但它对我有效。

function explode_adv($openers, $closers, $togglers, $delimiters, $str)
{
    $chars = str_split($str);
    $parts = [];
    $nextpart = "";
    $toggle_states = array_fill_keys($togglers, false); // true = now inside, false = now outside
    $depth = 0;
    foreach($chars as $char)
    {
        if(in_array($char, $openers))
            $depth++;
        elseif(in_array($char, $closers))
            $depth--;
        elseif(in_array($char, $togglers))
        {
            if($toggle_states[$char])
                $depth--; // we are inside a toggle block, leave it and decrease the depth
            else
                // we are outside a toggle block, enter it and increase the depth
                $depth++;

            // invert the toggle block state
            $toggle_states[$char] = !$toggle_states[$char];
        }
        else
            $nextpart .= $char;

        if($depth < 0) $depth = 0;

        if(in_array($char, $delimiters) &&
           $depth == 0 &&
           !in_array($char, $closers))
        {
            $parts[] = substr($nextpart, 0, -1);
            $nextpart = "";
        }
    }
    if(strlen($nextpart) > 0)
        $parts[] = $nextpart;

    return $parts;
}

Usage is as follows. explode_adv takes 5 arguments:

使用如下。explode_adv接受5个参数:

An array of characters that open a block - e.g. [, (, etc.
打开一个块的一组字符，例如，(，等等)。
An array of characters that close a block - e.g. ], ), etc.
关闭块的一组字符，例如，]，等等。
An array of characters that toggle a block - e.g. ", ', etc.
用于切换块的字符数组——例如。“,”等。
An array of characters that should cause a split into the next part.
一个字符数组，它将导致下一部分的分裂。
The string to work on.
要处理的字符串。
