从字符串中的引号中提取时,如何包含等号和引号?

string regex php

bestprogrammerintheworld · 技术社区 · 3 年前

我有这个字符串:

$shortcode = '[csvtohtml_create include_rows="1-10" 
debug_mode="no" source_type="guess" path="largecsv" 
source_files="test?output=csv"  csv_delimiter="," ]'

我想检索属性及其值,甚至是引号中的等号或空格。

How to explode a string but not within quotes in php?

我有以下代码:

$args = preg_split('/"[^"]+"(*SKIP)(*F)|\h+/', $shortcode);
   
$attrs = [];
foreach( $args as $item )
{
    //Only use those items in array $args with = sign
    if ( strpos( $item , '=' ) !== false )
    {
        $sep = explode( '=', $item );
        $key = $sep[0];
        $value = $sep[1];
        $attrs[$key] = str_replace( '"', '', $value );
    }
}

$args = explode( '=', $sc );

Array attrs
      "include_rows" => "1-10"
      "debug_mode" => "no"
      "source_type" => "guess"
      "path" => "largecsv"
      "source_files" => "test.csv?output"
      "csv_delimiter" => ","

我想要的结果是:

Array attrs
      "include_rows" => "1-10"
      "debug_mode" => "no"
      "source_type" => "guess"
      "path" => "largecsv"
      "source_files" => "test.csv?output=csv"
      "csv_delimiter" => ","

等

我想我应该在这里的某个地方加上等号(或者是?=),但正则表达式不是我的强项。。。

$args = preg_split('/"[^"]+"(*SKIP)(*F)|\h+/', $shortcode);

你在正确的轨道上爆炸了等号。这个实现不需要 array_shift 那就去拿钥匙吧 implodes

<?php

$sc = '[csvtohtml_create include_rows="1-10" 
debug_mode="no" source_type="guess" path="largecsv" 
source_files="test?output=csv"  csv_delimiter="," ]';

$args = array_filter(array_map('trim', preg_split('/"[^"]+"(*SKIP)(*F)|\h+/', $sc)));
array_shift($args); // remove [csvtohtml
array_pop($args); // remove ]

$output = [];
foreach ($args as $arg) {
    $explode = explode('=', $arg);
    $key = array_shift($explode);
    $value = str_replace('"', '', implode('=', $explode)); // remove str_replace if you want to keep the extra set of quotes
    $output[$key] = $value;
}

print_r($output);

导致

Array
(
    [include_rows] => 1-10
    [debug_mode] => no
    [source_type] => guess
    [path] => largecsv
    [source_files] => test?output=csv
    [csv_delimiter] => ,
)

可以使用匹配属性名称及其值

([^\s=]+)=(?|"([^"]*)"|(\S+))

见 regex demo 细节

([^\s=]+) -组1:除空格和空格外的一个或多个字符 = 查尔斯
= = 签名
(?|"([^"]*)"|(\S+)) -分支重置组:
- "([^"]*)" " " 捕获到第1组,然后 "
- | -或
- (\S+) -第2组:任意一个或多个非空白字符

见 PHP demo

$sc = '[csvtohtml_create include_rows="1-10" 
debug_mode="no" source_type="guess" path="largecsv" 
source_files="test?output=csv"  csv_delimiter="," ]';
if (preg_match_all('~([^\s=]+)=(?|"([^"]*)"|(\S+))~', $sc, $ms)) {
    print_r(array_combine($ms[1],$ms[2]));
}

Array
(
    [include_rows] => 1-10
    [debug_mode] => no
    [source_type] => guess
    [path] => largecsv
    [source_files] => test?output=csv
    [csv_delimiter] => ,
)

可能更容易找到匹配项。然后你可以做任何事。我将其转换为查询字符串并解析为数组:

preg_match_all('/[^\s=]+="[^"]*"/', $shortcode, $result);
parse_str(implode('&', $result[0]), $result);

现在 $result 产量:

Array
(
    [include_rows] => "1-10"
    [debug_mode] => "no"
    [source_type] => "guess"
    [path] => "largecsv"
    [source_files] => "test?output=csv"
    [csv_delimiter] => ","
)
