.php files encrypted with IonCube

Start with your PHP file. If another file is needed, we'll show you what's missing. Maximum 10MB.

Only upload files you own, are authorized to analyze, or are lawfully permitted to recover, migrate, audit, or interoperate with. Do not upload third-party proprietary software without permission. This ordinary public preview does not use AI-assisted callback recovery; charged, trusted-account, and approved trusted-partner recovery may send supplied context and relevant decoded fragments to our configured third-party model provider. See Terms.

Decode IonCube PHP 8.4 files online

PHP 8.4 introduced property hooks, asymmetric visibility, and a new lazy-object API. IonCube's encoder for PHP 8.4 produces Zend bytecode that targets these new opcodes — and that means older decoders fail on 8.4 output. DecodePHP attempts recognized PHP 8.4-targeted builds and reports unsupported or protection-dependent cases explicitly.

Upload a recognized IonCube .php file targeting PHP 8.4. Eligible files get a free 20-line preview; files that need a license, companion file, or callback context return specific guidance.

IonCube 10–15

Support for recognized IonCube 10 through 15 builds across the listed PHP targets.

Supported PHP targets

Supported targets: PHP 5.0–5.6, 7.1–7.4, and 8.1–8.4. PHP 7.0 and 8.0 ionCube targets are not accepted.

Readable output

Recovered PHP is formatted for review where structure can be reconstructed; lint and test it before use.

Fast decoding

Routine files usually finish quickly. Uploads are limited to 10 MB; callback-key recovery can take several minutes.

100% online

Nothing to install locally. Uploads are processed server-side in isolated microVMs.

Account download

Download a viewable account result after processing completes.

IonCube 15 is the only release with full PHP 8.4 support. Earlier IonCube versions cannot compile for 8.4 targets.

What PHP 8.4 introduced

Decoders for PHP 8.4 need to reconstruct opcodes for these language features specifically:

  • Property hooks (public string $name { get => ...; set => ...; })
  • Asymmetric visibility (public private(set) string $id)
  • Lazy objects (\\ReflectionClass::newLazyGhost)
  • #[\\Deprecated] attribute
  • array_find(), array_find_key(), array_any(), array_all()
  • Chaining new without parens (new Foo()->bar())
  • HTML5-aware DOM API

Why PHP 8.4 decoding still matters

  • PHP 8.4 is the current cutting-edge release. New encoded apps released in 2025–2026 are increasingly 8.4-only.
  • Property hooks and asymmetric visibility in 8.4 are major semantic additions — encoded apps using them require exact 8.4 decoding.
  • Hosting providers aggressive on PHP upgrades (Laravel Cloud, Cloudflare Workers PHP beta) offer 8.4 exclusively for some runtimes.

Gotchas specific to decoding PHP 8.4

  • Property hooks add ZEND_ACC_PROPERTY_HOOK opcodes with embedded get/set lambdas — this is the biggest bytecode change since enums.
  • Asymmetric visibility introduces two visibility flags per property (read vs write). A decoder that stores only one flag will miscompile.
  • Lazy objects use an entirely new ZEND_AST_OP_LAZY_OBJECT node. Pre-8.4 decoders cannot represent it.
  • array_find / array_any / array_all are opcodes optimized to INIT_FCALL_BY_NAME specializations — decoded output may need function-name normalization.

File signature

An IonCube-encoded file targeting PHP 8.4 typically begins with a header that looks like this:

<?php //004fb7a8\n<?php //PHP84+\nHR+cPkX...

The first line encodes a header hash, the second encodes the PHP target, and the remainder is the encrypted bytecode payload. Our free in-browser version detector reads these bytes to identify the exact encoder and PHP target for your file.

Frequently asked questions

Does your decoder support IonCube with PHP 8.4?
DecodePHP accepts recognized IonCube builds targeting PHP 8.4. A matching license, companion file, or callback context may still be required.
Why do I need a special decoder for PHP 8.4?
Each PHP version uses a different Zend VM opcode set. DecodePHP has an explicit ionCube allowlist: PHP 5.0–5.6, 7.1–7.4, and 8.1–8.4; PHP 7.0 and 8.0 ionCube targets are not accepted.
Will my decoded PHP 8.4 code be runnable as-is?
Lint and test the recovered source on PHP 8.4 before using it. Formatting and source-level choices may differ, and decompiled output can require manual fixes.
Can you decode files compiled with IonCube 15 for PHP 8.4?
Recognized IonCube 15 files targeting PHP 8.4 can be attempted. Unrecognized builds or missing protection artifacts return an explicit error instead of a decoded result.
How much does it cost to decode a PHP 8.4 IonCube file?
Use credits from a one-time pack. Eligible files get a free 20-line preview. A credit is used when a viewable result is produced, including viewable partial callback-key output.
Do you support IonCube Loader installation for PHP 8.4?
We focus on decoding, not loader installation. If you need the runtime IonCube Loader for PHP 8.4, refer to IonCube Ltd's official loader wizard.
