The string manipulation functions are found in the Illuminate\Support namespace and are callable on the Str object.

Most of the functions also have shorter snake_case aliases. For example, the Str::endsWith() method is identical to the global ends_with() function. We are free to use whichever one we prefer in our application.

Boolean functions

The following functions return the true or false values:

  • The is method checks whether a value matches a pattern. The asterisk can be used as a wildcard character as shown here:
    Str::is('projects/*', 'projects/php/'); // Returns true
  • The contains method, as shown in the following code, checks whether a string contains a given substring:
    Str::contains('Getting Started With Laravel', 'Python');
    // returns false
  • The startsWith and endsWith methods, as shown in the following code, check whether a string starts or ends with one or more substrings:
    Str::startsWith('.gitignore', '.git'); // Returns true
    Str::endsWith('index.php', ['html', 'php']); // Returns true

As you can see from the preceding examples, these methods are handy for validation filenames and similar dat
