// to string

StringHelper

Empty String Determine

use Windwalker\String\StringHelper;

StringHelper::isEmpty('');      // true
StringHelper::isEmpty(0);       // false
StringHelper::isEmpty(array()); // true
StringHelper::isEmpty(null);    // true

StringHelper::isZero(0);    // true
StringHelper::isZero('0');  // true
StringHelper::isZero('');   // false
StringHelper::isZero(null); // false

Quote

// Default quote is `"`
StringHelper::quote('foo'); // "foo"

// Custom quotes
StringHelper::quote('foo', array('{{', '}}')); // {{foo}}

// Backquote
StringHelper::backquote('foo'); // `foo`

More Methods

StringHelper::increment('Title'); // Title (2)
StringHelper::increment('Title', StringHelper::INCREMENT_STYLE_DASH); // Title-2

StringHelper::at('歡迎光臨', 2); // 光

StringHelper::collapseWhitespace('Welcome   to   Windwalker'); // 'Welcome to Windwalker'

StringHelper::endsWith('歡迎光臨', '光臨' [, $caseSensive = true]); // true

StringHelper::startsWith('歡迎光臨', '歡迎' [, $caseSensive = true]); // true

// Default callback is array_push
StringHelper::explode('.', 'foo.bar', 3); // array('foo', 'bar', null);

// Shift null
StringHelper::explode('.', 'foo.bar', 3, 'array_shift'); // array(null, 'foo', 'bar');

// Limit
StringHelper::explode('.', 'foo.bar.yoo', 2); // array('foo', 'bar.yoo');

// Useful to use list()

list($foo, $bar, $yoo) = StringHelper::explode('.', 'foo.bar', 3);

StringInflector

use Windwalker\String\StringInflector;

    $string = $inflector->toPular(); // categories
}

}
