Why is PHP partially case senstive? I can only speculate that this stems from very early versions, probably PHP/FI 2.0. The manual explicitely states: Keep in mind that PHP/FI function names are not case sensitive. Most user input, such as GET and POST parameters, has always been registered as global variables, back then. Treating these as case … Read more

Pass re.IGNORECASE to the flags param of search, match, or sub:
The Character class of Java API has various functions you can use. You can convert your char to lowercase at both sides: There are also a methods you can use to verify if the letter is uppercase or lowercase:
You can use the \c escape sequence anywhere in the pattern. For example: /\ccopyright or /copyright\c or even /copyri\cght To do the inverse (case sensitive matching), use \C (capital C) instead

To test if the string paragraph contains the string word (thanks @QuarterMeister) Where culture is the instance of CultureInfo describing the language that the text is written in. This solution is transparent about the definition of case-insensitivity, which is language dependent. For example, the English language uses the characters I and i for the upper and lower case versions of the ninth letter, whereas the Turkish language uses … Read more
strncasecmp The strcasecmp() function performs a byte-by-byte comparison of the strings s1 and s2, ignoring the case of the characters. It returns an integer less than, equal to, or greater than zero if s1 is found, respectively, to be less than, to match, or be greater than s2. The strncasecmp() function is similar, except that it compares no more than n bytes of s1 and s2…
Assuming ASCII strings: As of Python 3.3, casefold() is a better alternative: If you want a more comprehensive solution that handles more complex unicode comparisons, see other answers.
