.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.

Decode IonCube PHP 8.3 files online

PHP 8.3 is a long-term support release used by most production stacks in 2025–2026. IonCube encoders targeting PHP 8.3 emit bytecode for new features like typed class constants and readonly classes — older decoders can't handle those opcodes and skip or corrupt the output. DecodePHP attempts recognized PHP 8.3-targeted builds and reports unsupported or protection-dependent cases explicitly.

Upload a recognized IonCube PHP 8.3 file. 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

IonCube encoders that target it
IonCube 14 and 15 both target PHP 8.3. IonCube 15 adds better support for typed constants.

What PHP 8.3 introduced

Decoders for PHP 8.3 need to reconstruct opcodes for these language features specifically:

  • Typed class constants (const int FOO = 5)
  • #[Override] attribute
  • json_validate() built-in
  • Readonly class inheritance relaxations
  • Deep cloning of readonly properties (__clone behavior)
  • Anonymous readonly classes
  • Dynamic class constant fetch (X::{$name})

Why PHP 8.3 decoding still matters

  • PHP 8.3 is the current LTS-style deployment target for most production stacks in 2026.
  • New commercial scripts that ship encoded increasingly target 8.3 exclusively — rejecting older PHP runtimes.
  • Migrating an encoded 7.4 or 8.1 app to 8.3 is the most common modernization project we see.

Gotchas specific to decoding PHP 8.3

  • Typed class constants introduce the new CONST_TYPE opcode. Decoders that miss this field produce syntactically-broken output.
  • #[Override] is an attribute, not an opcode change, but decoded output should preserve attributes for static-analysis tooling to still work.
  • Anonymous readonly classes compile to a unique opcode path — some IonCube 14 early builds misheard this as regular anon classes.

File signature

An IonCube-encoded file targeting PHP 8.3 typically begins with a header that looks like this:

<?php //004fb6a7\n<?php //PHP83+\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 8.3?
DecodePHP accepts recognized IonCube builds targeting PHP 8.3. A matching license, companion file, or callback context may still be required.
What changed in PHP 8.3 that affects IonCube decoding?
PHP 8.3 added typed class constants, #[Override] attributes, and readonly class support. IonCube's 8.3-targeted encoder emits opcodes for these features — our decoder lifts them back into readable modern PHP.
Can I decode a file encoded with IonCube 14 for PHP 8.3?
A recognized IonCube 14 file targeting PHP 8.3 can be attempted. DecodePHP does not claim every encoder/PHP cross-version pair, and required protection artifacts or callback context may still be needed.
Is there a free preview for PHP 8.3 files?
Eligible PHP 8.3 files get a free 20-line preview when decoding completes without an unresolved protection requirement.
Will decoded output run on PHP 8.3?
Lint and test the recovered source on PHP 8.3 before using it; decompiled output can require manual fixes.
What if my hosting still uses PHP 8.2 or older?
Use the page matching the encoded target. Listed ionCube targets include PHP 5.x, 7.1–7.4, and 8.1–8.4; PHP 7.0 and 8.0 ionCube targets are not accepted.
