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 Method | Difference |
|---|---|
Phar::apiVersion() Method | Returns the supported Phar API version as a string. |
PHP_VERSION | Describes 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
| Mistake | Correct 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.
