Path

  • join(string ...$segments): string

    Join paths using native DIRECTORY_SEPARATOR constant

  • scan_for_files(string $directory, string $file_regexp, array $ignore = []): array

    Scan for files recursively in a given directory that match a given pattern. Returns an array of SplFileInfo

    This supports ignoring files

    Note The / in the ignore patterns do not need to be escaped

    All paths get converted to a real path and all separators get converted to a forward slash /

    //return all php files
Utils::$Path::scan_for_files(__DIR__, "\.php$");
Utils::$Path::scan_for_files(__DIR__, "\.php$",
    ignore: ['/vendor/?.*']
);

  • getFileSystemIteratorFilter

    This custom FileSystemIterator allows ignoring patterns (ignoring is leaf type agnostic, the pattern will validate against directories and paths)

    FileSystemIterator constructor

    public function __construct(
    RecursiveIterator $iterator,
    private readonly array $ignore = []
) {}

    FileSystemIterator example usage

    $dir_it = new RecursiveDirectoryIterator(__DIR__, RecursiveDirectoryIterator::SKIP_DOTS);
$fs_it = Utils::$Path::getFileSystemIteratorFilter($dir_it, $ignore_array);

Preg

  • count(string $pattern, string $subject, int $flags = 0, int $offset = 0) : int

    Returns the number matches for a given a pattern

    This is guaranteed to return an integer

  • match_all(string $pattern, string $subject, &$matches, int $flags = 0, int $offset = 0)

    Return all matches of a given pattern

    $str = <<<'A'
https://johndoe:pa$$w0rd@example.com

https://janedoe:pa$$w0rd@example.com
A;

Utils::$Regex::match_all('/https:\/\/(?:(?<username>\w+):(?<password>\S+))@example\.com/', $str, $matches);

$john_match = $matches[0];

//accessing match metadata
$john_match->value; // https://johndoe:pa$$w0rd@example.com
$john_match->start; // 0
$john_match->end; // 36

//accessing groups
$john_match->groups->{'1'}; // johndoe
$john_match->groups->username; // johndoe
$john_match->g1; //johndoe

$john_match->groups->{'2'}; // pa$$w0rd
$john_match->groups->password; // pa$$w0rd
$john_match->g2; //pa$$w0rd

Strings

  • charAt(string $value, int $index) : ?string

  • utf8(string $value): ?string

  • explode_implode( string $value, string $explode_delimiter, ?callable $foreach = null, ?string $implode_delimiter = null, int $limit = PHP_INT_MAX ) : string

    Utility to quickly explode a string, optionally perform a mapping operation on each value and then implode it back

    Note the foreach map is applied to the exploded operation

    $str = "key=value; key2=value2; key3=value3";

$result = Utils::$String::explode_implode(
    $str,
    explode_delimiter: ";",
    implode_delimiter: " / ",
    foreach: fn($i) =>
        Utils::$String::explode_implode($i, "=", null, " => ")
);

echo $result; // "key => value /  key2 => value2 /  key3 => value3"
