The function array_search is used to search for a specific value in an array and return the corresponding key. Here is how it is used:<\/p>\n

mixed<\/span> array_search<\/span> ( mixed<\/span> $needle<\/span> , array<\/span> $haystack<\/span> [, bool<\/span> $strict<\/span> = false<\/span> ] )\r\n<\/code><\/pre>\n
Instructions for parameters:<\/p>\n
    \n
  1. $needle: The value to search for.<\/li>\n
  2. $haystack: Array to be searched.<\/li>\n
  3. $strict (optional): Specifies whether to use strict mode for comparison, default is false. If set to true, data types will be compared during the search.<\/li>\n<\/ol>\n
    Return value:<\/p>\n
      \n
    1. Return the key name corresponding to the specified value if found.<\/li>\n
    2. If the specified value is not found, return false.<\/li>\n<\/ol>\n
      I’m sorry, I don’t understand the question.<\/p>\n
