The ascii helper method in Laravel converts a UTF-8 encoded string into its ASCII equivalent. It accepts a single argument, which should be a string or something that can be cast into a string. This function is useful when communicating with other software platforms that require ASCII, or when complying with protocols like HTTP. In Laravel 5, the ascii function uses the stringy library, while previous versions of Laravel used the patchwork/utf8 package.

Studly caps is a formatting style for text that involves capitalizing the first letter of each word while removing certain word separators. Laravel provides a Str::studly method to implement this formatting. Examples include transforming "my words" to "MyWords" and "my-WORDS" to "MyWORDS". Pascal case, which is similar to camel case with the first letter capitalized, can also be achieved with studly. There is also a global function studly_case available as a shortcut to Str::studly.

Learn how to use the e function in PHP to sanitize user input and prevent potential security vulnerabilities. The e function is a convenient wrapper for PHP's htmlentities function and utilizes the UTF-8 character encoding. By using the e function, you can safely display user input in the browser without the risk of executing malicious code. Discover how to implement the e function and ensure that the browser renders user input as intended.

Learn how to use the camel helper function in Laravel's Illuminate\Support\Str class to convert strings to camel case. Discover examples of how to convert various forms of strings to camel case, and understand that the function only affects the casings of the first character.

Learn how to use the contains helper method in PHP to check if a given value contains any of the specified needles. The contains method returns true if any needles are found in the haystack, otherwise it returns false.

The endsWith helper method in Laravel is used to check if a string ends with any of the provided characters. It returns true if the string ends with any of the characters and false otherwise. This method can be used in combination with PHP's range function to check if a string ends with any alphabetical character. Additionally, there is a shortcut function ends_with that can be used instead of calling Str::endsWith directly.

The equals method in Laravel compares two strings to check if they are the same. It returns a boolean value indicating whether the strings are equal or not. This method implements a constant-time algorithm, so the time it takes to complete doesn't increase with the size of the strings. However, starting from Laravel version 5.2, it is recommended to use PHP's built-in hash_equals function instead. The equals method may leak length information through timing attacks if the input strings have different lengths.

The finish helper method is a useful tool for ensuring that a given value ends with a specified character or string. It's commonly used for constructing URIs or file paths, and can accept any string of characters as the ending. This helper function is particularly handy when combined with the slug method, allowing for easy generation of interesting results. Additionally, for convenience, there is a shortcut function called str_finish that can be used in the global namespace.

The is helper method is used to determine if a value matches a specific pattern. It returns true if the value matches the pattern, and false otherwise. You can use wildcards in the pattern for flexible matching. The str_is function is a shortcut for calling the is method. It can be used globally without the need for importing the Str class.

The length helper method in Laravel returns the length of a given value in PHP. It utilizes PHP's internal character encoding to calculate the length. For example, Str::length('12345') would return 5, and Str::length(str_repeat('n', 120)) would return 120. Additionally, str_repeat is a PHP function that repeats a given input a specified number of times, such as str_repeat('n', 120) resulting in a string with 120 occurrences of the character 'n'.

The limit method is a useful helper function in Laravel's Str class that ensures a provided value does not exceed a specified limit. It appends a given end sequence if the value is trimmed. This is particularly useful when displaying lengthy user-generated content to avoid issues with UI layouts. The str_limit function is a shortcut to calling Str::limit and is defined in the global namespace.

The lower helper method converts a given value to lowercase. Use the lower function by passing the desired value as an argument. For example, Str::lower('ALL LOWER CASED') will output "all lower cased".

Learn how to use the parseCallback helper method in Laravel to split a string with a class name and method name.
