This package provides a handy way to work with strings in php.

Spatie is a webdesign agency in Antwerp, Belgium. You'll find an overview of all our open source projects on our website.

Install

You can install this package via composer:

composer require spatie/string

Postcardware

You're free to use this package (it's MIT-licensed), but if it makes it to your production environment we highly appreciate sending us a postcard from your hometown, mentioning which of our package(s) you are using.

Our address is: Spatie, Samberstraat 69D, 2060 Antwerp, Belgium.

All postcards are published on our website.

Usage

First you must wrap a native string in a String-object. This can be done with the string-function.

string('myFirstString');

From then on you can chain methods like there's no tomorrow:

echo string('StartMiddleEnd')->between('Start', 'End')->toUpper(); // outputs "MIDDLE"

Of course you can keep concatenate the output with the .-operator we all know and love.

echo 'stuck in the ' . string('StartMiddleEnd')->between('Start', 'End')->toLower() . ' with you';

You can also use offsets to manipulate a string.

echo string('hello')[1]->toUpper(); //outputs "E"

$string = string('gray');
$string[2] = 'e';
echo $string->toUpper(); //outputs "GREY"

Provided methods

between

/**
 * Get the string between the given start and end.
 *
 * @param $start
 * @param $end
 * @return \Spatie\String\String
 */
public function between($start, $end)

Example:

string('StartMiddleEnd')->between('Start', 'End')->toUpper(); // MIDDLE

toUpper

/**
 * Convert the string to uppercase.
 *
 * @return \Spatie\String\String
 */
public function toUpper()

Example:

string('string')->toUpper(); // STRING

toLower

/**
 * Convert the string to lowercase.
 *
 * @return \Spatie\String\String
 */
public function toLower()

Example:

string('STRING')->toLower(); // string

tease

/**
 * Shortens a string in a pretty way. It will clean it by trimming
 * it, remove all double spaces and html. If the string is then still
 * longer than the specified $length it will be shortened. The end
 * of the string is always a full word concatinated with the
 * specified moreTextIndicator.
 *
 * @param int $length
 * @param string $moreTextIndicator
 * @return \Spatie\String\String
 */
public function tease($length = 200, $moreTextIndicator = '...')

Example:

$longText = 'Now that there is the Tec-9, a crappy spray gun from South Miami. This gun is advertised as the most popular gun in American crime. Do you believe that shit? It actually says that in the little book that comes with it: the most popular gun in American crime.'
string($longText)->tease(10); // Now that...

replaceFirst

/**
 * Replace the first occurrence of a string.
 *
 * @param $search
 * @param $replace
 * @return \Spatie\String\String
 */
public function replaceFirst($search, $replace)

Example:

$sentence = 'A good thing is not a good thing.';
string($sentence)->replaceFirst('good', 'bad'); // A bad thing is not a good thing.

replaceLast

/**
 * Replace the last occurrence of a string.
 *
 * @param $search
 * @param $replace
 * @return \Spatie\String\String
 */
public function replaceLast($search, $replace)

Example:

$sentence = 'A good thing is not a good thing.';
string($sentence)->replaceLast('good', 'bad'); // A good thing is not a bad thing.

prefix

/**
 * Prefix a string.
 *
 * @param $string
 * @return \Spatie\String\String
 */
public function prefix($string)

Example:

string('world')->prefix('hello '); //hello world

suffix

/**
 * Suffix a string.
 *
 * @param $string
 * @return \Spatie\String\String
 */
public function suffix($string)

Example:

string('hello')->suffix(' world'); // hello world

concat

This is identical to the suffix-function.

possessive

/**
 * Get the possessive version of a string.
 *
 * @return \Spatie\String\String
 */
public function possessive()

Example:

string('Bob')->possessive(); // Bob's
string('Charles')->possessive(); // Charles'

segment

/**
 * Get a segment from a string based on a delimiter.
 * Returns an empty string when the offset doesn't exist.
 * Use a negative index to start counting from the last element.
 * 
 * @param string $delimiter
 * @param int $index
 * 
 * @return \Spatie\String\String
 */
public function segment($delimiter, $index)

Related methods:

/**
 * Get the first segment from a string based on a delimiter.
 * 
 * @param string $delimiter
 * 
 * @return \Spatie\String\String
 */
public function firstSegment($delimiter)

/**
 * Get the last segment from a string based on a delimiter.
 * 
 * @param string $delimiter
 * 
 * @return \Spatie\String\String
 */
public function lastSegment($delimiter)

Example:

string('foo/bar/baz')->segment('/', 0); // foo
string('foo/bar/baz')->segment('/', 1); // bar
string('foo/bar/baz')->firstSegment('/'); // foo
string('foo/bar/baz')->lastSegment('/'); // baz

pop

/**
 * Pop (remove) the last segment of a string based on a delimiter
 * 
 * @param string $delimiter
 * 
 * @return \Spatie\String\String
 */
public function pop($delimiter)

Example:

string('foo/bar/baz')->pop('/'); // foo/bar
string('foo/bar/baz')->pop('/')->pop('/'); // foo

contains

/**
 * Check whether a string contains a substring
 *
 * @param array|string $needle
 * @param bool $caseSensitive
 * @param bool $absolute
 *
 * @return bool
 */
public function contains($delimiter)

Example:

string('hello world')->contains('world'); // true
string('hello world')->contains('belgium'); // false

Integration with underscore.php

In addition to the methods described above, you can also use all string methods provided by Maxime Fabre's underscore package.

For example:

string('i am a slug')->slugify()` // returns 'i-am-a-slug'

Of course, you can chain underscore's methods with our own.

string('i am a slug')->slugify()->between('i', 'a-slug`) // returns '-am-'

Be aware that some underscore methods do not return a string value. Such methods are not chainable.

string('freek@spatie.be')->isEmail() // returns true;
