echo $str->random(3, -1, 'fobarz');
// zfa
$str = new Str('');
echo $str->random(3);
// 1ho
Appends a random string consisting of $possibleChars, if specified, of given $size or random length between $size and $sizeMax to the original string.
- param int $size The desired length of the string. Defaults to 4.
- param int $sizeMax If given and is > $size, the generated string will have random length between $size and $sizeMax. Defaults to -1.
- param string $possibleChars If given, specifies allowed characters to make the string of. Defaults to ASCII alphanumeric chars.
- return Str
Example:
$str = new Str('foo');
echo $str->appendUniqueIdentifier(3, -1, 'foba_rz');
// foozro
Wraps each word in the string with specified $quote.
- param string $quote Defaults to ".
- return Str
Example:
$str = new Str('foo bar baz');
echo $str->quote('*');
// *foo* *bar* *baz*
Unwraps each word in the original string, deleting the specified $quote.
- param string $quote Defaults to ".
- return Str
Example:
$str = new Str('*foo* bar* ***baz*');
echo $str->unquote('*');
// foo bar baz
Splits on whitespace, returning an array of strings corresponding to the words in the string.
- return array
Example:
$str = new Str('foo bar baz');
echo $str->words();
// ['foo', 'bar', 'baz']
Cuts the original string in pieces of $step size.
- param int $step
- return array
Example:
$str = new Str('foo bar baz');
echo $str->chop(2);
// ['fo', 'o ', 'ba', 'r ', 'ba', 'z']
Joins the original string with an array of other strings with the given $separator.
- param string $separator
- param array $otherStrings Defaults to empty array.
- return Str
Example:
$str = new Str('foo');
echo $str->join('*', ['bar', 'baz']);
// foo*bar*baz
Returns the substring of the string from the last occurrence of $delimiter to the end.
- param string $delimiter
- return Str
Example:
$str = new Str('Acme/foo');
echo $str->pop('/');
// foo
Returns the substring of the original string from beginning to the first occurrence of $delimiter.
- param string $delimiter
- return Str
Example:
$str = new Str('Acme/foo');
echo $str->shift('/');
// Acme
Returns the substring of the original string from the first occurrence of $delimiter to the end.
- param string $delimiter
- return Str
Example:
$str = new Str('Acme/foo/bar');
echo $str->shiftReversed('/');
// foo/bar
Returns the substring of the original string from the beginning to the last occurrence of $delimiter.
- param string $delimiter
- return Str
Example:
$str = new Str('Acme/foo/bar');
echo $str->popReversed('/');
// Acme/foo
