if (strpos('string with lots of words', 'words') != false) Example: PHP 7. This function returns the position of the needle string, or it returns false if the string needle is not found. In PHP 7.x, strops() function is used to check if a given string contains another string or not. A couple of functions for checking if a string contains any of the strings in an array, or all of the strings in an array: addcslashes () Returns a string with backslashes in front of the specified characters. Returns the position of where the needle exists relative to the beginning of the haystack string (independent of offset). No installation is required to use these functions. The strcontains () function returns the boolean 'true' if the substring is found in the string and 'false' otherwise. The str_contains function checks if a first-string is contained in the second string and it returns a true /false Boolean value based on whether the string is found or not. The PHP string functions are part of the PHP core. In PHP 8 and higher, you can use strcontains () function to check if a string contains the desired substring. In PHP 8, str_contains function determines if a string contains a given substring anywhere.
