A loop library for PHP.

Installation

Run the following command inside of your project directory.

composer require enzyme/loopy

Usage

Simple

A simple loop over an array.

use Enzyme\Loopy\Each;

$array = [1, 2, 3];

Each::shallow()->begin($array, function($bag) {
    echo $bag->value() . ', ';
});

The above will output 1, 2, 3,

Deep

A deep loop over a multidimensional array.

use Enzyme\Loopy\Each;

$array = [1, 2, 3, 4 => [4, 5, 6]];

Each::deep()->begin($array, function($bag) {
    echo $bag->value() . ', ';
});

The above will output 1, 2, 3, 4, 5, 6,

Filtered

A loop over a filtered array.

use Enzyme\Loopy\Each;
use Enzyme\Loopy\Filters\SkipNulls;

$array = [1, 2, null, 4, 5];

Each::deep(new SkipNulls)->begin($array, function($bag) {
    echo $bag->value() . ', ';
});

The above will output 1, 2, 4, 5,

Bags

The $bag object passed to the callback function generally contains the follow information.

Key	Value	Description
key()	Key	The enumerable objects key for the given pass.
value()	Value	The enumerable objects value for the given pass.
cycle()	Current cycle (0 based)	How many times around the entire object the looper has gone.
depth()	Current depth (0 based)	The current depth of the pass, for multidimensional arrays.
index()	Current index (0 based)	The current index, in this case index is really a count of the number of items encountered so far.

Filters

Filter	Description
SkipNulls	Will skip over any values which are null.
Regex	Will test value against the supplied regular expression.
Equal	Will test value for equality against the given rule. (===)
Less	Will test that value is less than the give rule, or less than or equal if parameter 2 in the constructor is set to true.
Greater	Will test that value is greater than the give rule, or greater than or equal if parameter 2 in the constructor is set to true.

enzyme/loopy 适用场景与选型建议

enzyme/loopy 是一款基于 PHP 开发的 Composer 扩展包，目前已累计 19 次下载、GitHub Stars 达 1，最近一次更新时间为 2015 年 12 月 09 日，在 PHP 生态内属于活跃度较高的组件。

它主要适用于以下技术方向：「php」「loop」「for」「enzyme」「while」「foreach」等业务场景。在实际项目中，围绕这些方向常见需要落地的问题包括：接口对接、性能调优、并发安全、与既有框架（Laravel / ThinkPHP / Yii / Webman 等）的兼容适配，以及生产环境的日志埋点与稳定性保障。

我们在过去多个企业项目中使用过 enzyme/loopy 或与其功能相近的方案，如果你在选型或落地过程中遇到问题，例如 版本兼容、二次改造、私有化封装、与内部系统对接、生产 BUG 排查，欢迎联系我们协助评估。

围绕 enzyme/loopy 我们能提供哪些服务？

定制开发 / 二次开发

基于 enzyme/loopy 在你已有业务上做功能扩展、字段裁剪、UI 适配、与内部账号 / 权限 / 日志系统的深度对接。

BUG 修复 & 性能优化

线上偶发问题、内存泄漏、慢查询、并发异常等排查修复；针对高流量场景做缓存、队列、索引层面的调优。

项目外包 & 长期维护

承接完整的项目从需求 → 设计 → 开发 → 上线 → 长期运维；也可按月提供技术保姆服务。
