PHP strpbrk() Function: Find Characters in a String

The PHP function strpbrk() searches a haystack string for the first occurrence of any character from a specified char_list.

Signature: string strpbrk(string $haystack, string $char_list) It returns the portion of $haystack starting from the first matched character; if no character from $char_list is found, it returns FALSE.

Parameters $haystack: The string to be searched. $char_list: A string containing the characters to search for (case‑sensitive).

Return value

A substring of $haystack beginning with the first matched character, or FALSE if no match is found.

Example 1

```php php $text = 'This is a Simple text.'; // Output "is is a Simple text.", because 'i' is matched first echo strpbrk($text, 'mi'); // Output "Simple text.", because the search is case‑sensitive echo strpbrk($text, 'S'); ? ```

In the first call, the function finds the character i (from 'mi') and returns the substring starting at that position. In the second call, only an uppercase S matches, so the returned substring starts at S.

Example 2

```php php echo strpbrk("I love Shanghai!", "S"); // Outputs "Shanghai!" ? ```
