PHP Phar::apiVersion() Method: Usage and Examples

Returns the supported Phar API version as a string.

1 views Published Oct 17, 2026 Updated Oct 17, 2026

PHAR archives can package multiple resources into a single file. Phar::apiVersion() Method addresses a specific part of that process: returns the supported Phar API version as a string. The examples distinguish archive-level effects from member-level effects.

What Is Phar::apiVersion() Method?


Returns the supported Phar API version as a string.

Its syntax is:

Phar::apiVersion()

This function or method takes no parameters.

Return value: The declared return type is string. The API version is not the PHP runtime version.

Important: The API version is not the PHP runtime version.

Example 1: Basic Usage


The basic example focuses on the behavior of Phar::apiVersion() Method: returns the supported Phar API version as a string. Inputs are defined locally or shown as application-controlled paths.

<?php

echo Phar::apiVersion();

The displayed value, file content or return status depends on the input and surrounding environment. Results involving local paths, identifiers or generated files are not fixed values.

Example 2: A Different Use Case


This second example illustrates another input or execution condition for Phar::apiVersion() Method. Notice the different checks, arguments, or output handling.

<?php

$apiVersion = Phar::apiVersion();
if (version_compare($apiVersion, "1.0.0", ">=")) { echo "PHAR API supported"; }

This variation matters because the API version is not the PHP runtime version.

Practical Example: Working with Archive Entries


The following example demonstrates how Phar::apiVersion() Method fits into a more complete file or archive workflow, including inputs and appropriate checks.

<?php

$version = Phar::apiVersion();
$minimumVersion = "1.0.0";
if (version_compare($version, $minimumVersion, "<")) { throw new RuntimeException("PHAR API version too old"); }

The operation shown is an illustrative script. Adapt the filenames, required permissions, and error handling to your own controlled application environment before running it.

Important Behavior and Edge Cases


  • Function behavior: Returns the supported Phar API version as a string.
  • Limitation: The API version is not the PHP runtime version.

Comparison With Related Functions


Function or MethodDifference
Phar::apiVersion() MethodReturns the supported Phar API version as a string.
PHP_VERSIONDescribes the PHP runtime version; Phar::apiVersion() describes the Phar API version.

Use Phar::apiVersion() Method for the specific behavior described above. The related operation, PHP_VERSION, serves a different purpose; do not substitute it unless that different behavior is intended.

Common Beginner Mistakes


MistakeCorrect Approach
Confusing archive-level operations with operations on individual entries.The API version is not the PHP runtime version. Confirm the expected archive format, member path and read/write permissions.
Treating PHP_VERSION as an interchangeable replacement for Phar::apiVersion() Method.Describes the PHP runtime version; Phar::apiVersion() describes the Phar API version.

Key Takeaways


  • Returns the supported Phar API version as a string.
  • The API version is not the PHP runtime version.
  • Related operation: PHP_VERSION — Describes the PHP runtime version; Phar::apiVersion() describes the Phar API version.

Phar::apiVersion() Method is useful when its specific behavior matches your application requirement. Keep paths controlled, check failures, and handle environment-dependent operations deliberately.
