How to Preserve Quoted Text as Single Words When Using PHP's explode()?

Treating Quoted Words as Single Words in PHP explode

How can we break down a string, as seen below, using explode() while preserving quoted text as single words?

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

Copy after login

Expected Output:

["Lorem", "ipsum", "dolor sit amet", "consectetur", "adipiscing elit", "dolor"]

Copy after login

Despite attempts using the following code, the current implementation segments each word in the string:

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

Copy after login

Solution:

To accurately capture quoted words as single entities, we can leverage preg_match_all():

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

Copy after login

This refined syntax handles even escaped quotes within quoted phrases.

Breakdown of Regex:

"(?:         # Start non-capture group 1
  \        #   Match backslash character
  .         #   Match any character except line breaks
  |         #   Or
  [^\"]    #   Match any character except backslash and double quotes
)*          # End non-capture group 1 and repeat it zero or more times
"           # Match double quotes
|           # Or
\S+         # Match one or more non-whitespace characters

Copy after login

Handling " Instead of Double Quotes:

Should the need arise to deal with " in place of double quotes, utilize this adjusted regex:

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