Preserving Words in Quotes While Splitting Strings in PHP
When you need to split a string into an array, it can be challenging if the string contains words enclosed in quotes that should remain intact. In this case, you want to explode the following string:
Lorem ipsum "dolor sit amet" consectetur "adipiscing elit" dolor
Into this array:
array("Lorem", "ipsum", "dolor sit amet", "consectetur", "adipiscing elit", "dolor")
Rather than splitting the text within the quotation marks, you can employ a preg_match_all(...) function to achieve this:
$text = 'Lorem ipsum "dolor sit amet" consectetur "adipiscing \"elit" dolor';
preg_match_all('/"(?:\\.|[^\\"])*"|\S+/', $text, $matches);
This regular expression works as follows:
- It matches either a sequence of characters enclosed in double quotes (escaped quotes are also handled).
- Or, it matches any non-whitespace character one or more times.
The resulting $matches array will contain the desired split words:
Array
(
[0] => Array
(
[0] => Lorem
[1] => ipsum
[2] => "dolor sit amet"
[3] => consectetur
[4] => "adipiscing \"elit"
[5] => dolor
)
)
By utilizing this approach, you can effectively explode strings while preserving the integrity of quoted words.

How do I destroy a session in PHP using session_destroy()?
Jun 20, 2025 am 01:06 AM
To completely destroy a session in PHP, you must first call session_start() to start the session, and then call session_destroy() to delete all session data. 1. First use session_start() to ensure that the session has started; 2. Then call session_destroy() to clear the session data; 3. Optional but recommended: manually unset$_SESSION array to clear global variables; 4. At the same time, delete session cookies to prevent the user from retaining the session state; 5. Finally, pay attention to redirecting the user after destruction, and avoid reusing the session variables immediately, otherwise the session needs to be restarted. Doing this will ensure that the user completely exits the system without leaving any residual information.
