README

This library provides utility functions to help simplify menial tasks.

Where possible, this library provides some wrappers around some built-in functions. Our code should always throw exceptions instead of triggering errors/warnings/notices (excluding deprecation warnings).

Table of Contents:

• Arr
• Assert
• Deprecated
• Ini
• Json
• Serialization
• Str

Arr

Functions to deal with arrays.

Assert

Additional assertions built on Webmozart\Assert.

isArrayAccessible

Throws InvalidArgumentException if $value is not an array or object implementing ArrayAccess.

isArrayAccessible($value, string $message = ''): void

isInstanceOfAny

Throws InvalidArgumentException if $value is not an instance of one of the given classes/interfaces.

isInstanceOfAny($value, string[] $classes, string $message = ''): void

isIterable

Throws InvalidArgumentException if $value is not an iterable. Same as isTraversable(), just a better name.

isIterable($value, string $message = ''): void

Deprecated

Helper methods for triggering deprecation warnings.

warn

Shortcut for triggering a deprecation warning for something.

warn(string $subject, string|float $since = null, string $suggest = ''): void

Examples:

// Triggers warning: "Doing foo is deprecated."
Deprecated::warn('Doing foo');

// Triggers warning: "Doing foo is deprecated since 3.3 and will be removed in 4.0."
Deprecated::warn('Doing foo', 3.3);

// Triggers warning: "Doing foo is deprecated since 3.3 and will be removed in 4.0. Do bar instead."
Deprecated::warn('Doing foo', 3.3, 'Do bar instead');

method

Shortcut for triggering a deprecation warning for a method.

method(string|float $since = null, string $suggest = '', string $method = null): void

$suggest can be a sentence describing what to use instead. Or it can be a method name or class::method which will be converted to a sentence.

$method defaults to the method/function it was called from.

• If called from constructor, warning message says the class is deprecated.
• If called from magic method, warning message says the method/property called with is deprecated.

Example:

class Foo
{
    public function world()
    {
        // Triggers warning: "Foo::world() is deprecated since 3.3 and will be removed in 4.0. Use hello() instead."
        Deprecated::method(3.3, 'hello');
    }
}

cls

Shortcut for triggering a deprecation warning for a class.

cls(string $class, string|float $since = null, string $suggest = null): void

$suggest can be a sentence describing what to use instead. Or it can be a class name which will be converted to a sentence.

Examples:

// Triggers warning: "Foo\Bar is deprecated."
Deprecated::cls('Foo\Bar');

// Triggers warning: "Foo\Bar is deprecated. Use Bar\Baz instead."
Deprecated::cls('Foo\Bar', null, 'Bar\Baz');

Ini

Handles setting and retrieving values from PHP's configuration.

has

Checks whether the key exists.

has(string $key): bool

getStr

Get a string value. The default is returned if the key does not exist or the value is empty.

getStr(string $key, string $default = null): ?string

getBool

Get a boolean value. False is returned if the key does not exist or the value is empty.

getBool(string $key): bool

getNumeric

Get a numeric value. The default is returned if the key does not exist or the value is empty.

getNumeric(string $key, int|float $default = null): int|float|null

getBytes

Get a memory size value, such as memory_limit, and convert it to an integer. The default is returned if the key does not exist or the value is empty.

getBytes(string $key, int $default = null): ?int

set

Set a new value for the given key. Throws RuntimeException if the key does not exist, it is not editable, or something goes wrong.

set(string $key, ?scalar $value): void

Json

Handles JSON parsing/dumping with error handling.

parse

Parses JSON string to array or scalar. Throws ParseException if anything goes wrong.

parse(string $json, int $options = 0, int $depth = 512): string

We use seld/jsonlint to determine why the parsing failed and include it in the exception message.

dump

Dumps mixed to JSON string. Throws DumpException if anything goes wrong.

dump(mixed $data, int $options = JSON_PRETTY_PRINT | JSON_UNESCAPED_SLASHES | JSON_UNESCAPED_UNICODE, int $depth = 512): string

If input contains invalid UTF-8 characters we try to convert these for you before failing.

test

Returns whether the string is valid JSON.

test(string $json): bool

Serialization

Handles PHP serialization parsing/dumping with error handling.

parse

Parses PHP serialized string.

Throws ParseException if a serialized class cannot be found or anything else goes wrong.

parse(string $value, array $options = []): mixed

Note: $options parameter is ignored on PHP 5.

See unserialize() for details.

dump

Dumps anything to a PHP serialized string.

Throws DumpException if the input is not serializable or anything else goes wrong.

dump(mixed $value): string

Str

Common string methods.

replaceFirst

Replaces the first occurrence of the $search text on the $subject.

replaceFirst(string $subject, string $search, string $replace, bool $caseSensitive = true): string

replaceLast

Replaces the last occurrence of the $search text on the $subject.

replaceLast(string $subject, string $search, string $replace, bool $caseSensitive = true): string

removeFirst

Removes the first occurrence of the $search text on the $subject.

removeFirst(string $subject, string $search, bool $caseSensitive = true): string

removeLast

Removes the last occurrence of the $search text on the $subject.

removeLast(string $subject, string $search, bool $caseSensitive = true): string

splitFirst

Splits a $subject on the $delimiter and returns the first part.

splitFirst(string $subject, string $delimiter): string

splitLast

Splits a $subject on the $delimiter and returns the last part.

splitLast(string $subject, string $delimiter): string

endsWith

Returns whether the subjects ends with the search string.

endsWith(string $subject, string $search, bool $caseSensitive = true): bool

className

Returns the class name without the namespace, of a string FQCN, or object.

className(string|object $class): string

humanize

Converts a string from camel case and snake case to a human readable string.

humanize(string $text): string

camelCase

Converts a string from snake case to camel case.

camelCase(string $text, bool $lowercaseFirstChar = false): string

snakeCase

Converts a string from camel case to snake case.

snakeCase(string $text): string
