Methods
Checks if the string is valid for UTF-8 encoding.
Removes invalid code unit sequences from UTF-8 string.
Returns a specific character in UTF-8 from code point (0x0 to 0xD7FF or 0xE000 to 0x10FFFF).
Starts the $haystack string with the prefix $needle?
Ends the $haystack string with the suffix $needle?
Does $haystack contain $needle?
Returns a part of UTF-8 string.
Removes special controls characters and normalizes line endings, spaces and normal form to NFC in UTF-8 string.
Standardize line endings to unix-like.
Converts UTF-8 string to ASCII.
Converts UTF-8 string to web safe characters [a-z0-9-] text.
Truncates UTF-8 string to maximal length.
Indents UTF-8 string from the left.
Converts UTF-8 string to lower case.
Converts first character to lower case.
Converts UTF-8 string to upper case.
Converts first character to upper case.
Capitalizes UTF-8 string.
Case-insensitive compares UTF-8 strings.
Finds the length of common prefix of strings.
Returns number of characters (not bytes) in UTF-8 string.
Strips whitespace from UTF-8 string.
Pad a UTF-8 string to a certain length with another string.
Pad a UTF-8 string to a certain length with another string.
Reverse string.
Returns part of $haystack before $nth occurence of $needle (negative value means searching from the end).
Returns part of $haystack after $nth occurence of $needle (negative value means searching from the end).
Returns position of $nth occurence of $needle in $haystack (negative value means searching from the end).
Splits string by a regular expression.
Performs a regular expression match. Accepts flag PREG_OFFSET_CAPTURE (returned in bytes).
Performs a global regular expression match. Accepts flag PREG_OFFSET_CAPTURE (returned in bytes), PREG_SET_ORDER is default.
Perform a regular expression search and replace.
