php-regexHow to match a quotation mark in PHP regex?

To match a quotation mark in PHP regex, you can use the \ character before the quotation mark. This is known as an escape character and it tells the regex engine to treat the quotation mark as a literal character instead of a special character.

Example code

$string = 'This is a "test" string';
$pattern = '/".*"/';

if (preg_match($pattern, $string)) {
    echo 'Match found!';
}

Output example

Match found!

Code explanation

• $string = 'This is a "test" string';: This is the string that we are searching for a match in.
• $pattern = '/".*"/';: This is the regex pattern that we are using to search for a match. The \ character before the quotation mark tells the regex engine to treat the quotation mark as a literal character instead of a special character.
• if (preg_match($pattern, $string)) {: This is the condition that will be checked to see if a match is found.
• echo 'Match found!';: This is the code that will be executed if a match is found.
