The assertStringContainsStringIgnoringCase() function is a builtin function in PHPUnit and is used to assert a string containing a substring but ignoring the case of substring. This assertion will return true in the case if the string contains the substring as a substring ignoring case-sensitivity, else return false and in case of true the asserted test case got passed else test case got failed.
assertStringContainsStringIgnoringCase(string $substring, string $string, string $message = ''])
Parameters: This function accepts three parameters as shown in the above syntax. The parameters are described below:
- $substring: This parameter represents the string to be substring of given string.
- $string: This parameter is string for which the assert function will check whether it contains substring(ignoring case-sensitivity) or not.
- $message: This parameter takes string value. When the testcase got failed this string message got displayed as error message.
Below programs illustrate the assertStringContainsStringIgnoringCase() function:
