There are multiple ways to find and extract a date from a string using PHP. Here are a few examples:
1 2 3 4 5 6 7 |
$string = "Today is 25-11-2021"; $pattern = "/d{2}-d{2}-d{4}/"; // Matches date in format DD-MM-YYYY preg_match($pattern, $string, $matches); $date = $matches[0]; // Extracted date from the string echo $date; // Output: 25-11-2021 |
1 2 3 4 5 6 7 8 9 |
$string = "Today is November 25, 2021"; // Remove non-alphanumeric characters and extra spaces from the string $string = preg_replace('/[^a-zA-Z0-9s]/', '', $string); // Extract date using strtotime() $date = date("Y-m-d", strtotime($string)); echo $date; // Output: 2021-11-25 |
1 2 3 4 5 6 7 8 9 10 |
$string = "Today is 25th November, 2021"; // Remove non-alphanumeric characters and extra spaces from the string $string = preg_replace('/[^a-zA-Z0-9s]/', '', $string); // Extract date using DateTime class $date = DateTime::createFromFormat("j F, Y", $string); $dateFormatted = $date->format("Y-m-d"); echo $dateFormatted; // Output: 2021-11-25 |
Note: The approach may vary depending on the format and structure of the string you have. You may need to modify the regular expressions or the format used in strtotime() or DateTime::createFromFormat() to match your specific requirements.

Additionally, you can use the preg_match_all() function to find and extract multiple dates from a string. Here's an example:
1 2 3 4 5 6 7 8 9 10 11 |
$string = "The event dates are 2021-12-01 and 2022-01-15"; $pattern = "/d{4}-d{2}-d{2}/"; // Matches dates in format YYYY-MM-DD preg_match_all($pattern, $string, $matches); $dates = $matches[0]; // Extracted dates from the string foreach ($dates as $date) { echo $date . "<br>"; // Output: 2021-12-01, 2022-01-15 } |
In this example, the preg_match_all()
function is used with a regular expression pattern to find all occurrences of dates in the format "YYYY-MM-DD" in the given string. The extracted dates are stored in the $dates
array, which can be accessed and processed as needed.
