Add PHPUnit 7.x and 8.x to version constraint for PHP 7.1/7.2 support

[Copilot]

CI fails on PHP 7.1 and 7.2 because the PHPUnit constraint jumps from ^6.5 (max PHP 7.2) to ^9.4 (min PHP 7.3), skipping versions 7.x and 8.x that bridge the gap.

Changes

• Updated composer.json PHPUnit constraint from ^4.8|^5.5|^6.5|^9.4 to ^4.8|^5.5|^6.5|^7.5|^8.5|^9.4

Composer will now auto-select:

• PHPUnit 7.x for PHP 7.1-7.3
• PHPUnit 8.x for PHP 7.2-7.4
• PHPUnit 9.x for PHP 7.3+

Original prompt

Problem

The GitHub Actions test workflow is failing for PHP 7.2 (and will also fail for PHP 7.1) because of an incompatible PHPUnit version constraint in composer.json.

Error:

Problem 1
- Root composer.json requires phpunit/phpunit ^4.8|^5.5|^6.5|^9.4 -> satisfiable by phpunit/phpunit[9.6.33, 9.6.34].
- phpunit/phpunit[9.6.33, ..., 9.6.34] require php >=7.3 -> your php version (7.2.34) does not satisfy that requirement.

Root Cause:
The current PHPUnit constraint ^4.8|^5.5|^6.5|^9.4 skips PHPUnit versions 7.x and 8.x, which are the versions compatible with PHP 7.1 and 7.2. When Composer tries to resolve dependencies for PHP 7.2, it jumps to PHPUnit 9.x which requires PHP >=7.3.

Solution

Update the require-dev section in composer.json to include PHPUnit 7.x and 8.x:

"require-dev": {
    "phpunit/phpunit": "^4.8|^5.5|^6.5|^7.5|^8.5|^9.4"
}

PHPUnit version compatibility:

• PHPUnit 7.x supports PHP 7.1-7.3
• PHPUnit 8.x supports PHP 7.2-7.4
• PHPUnit 9.x supports PHP 7.3+

This will allow Composer to automatically select the appropriate PHPUnit version based on the PHP version being tested, enabling the test matrix to run successfully across all PHP versions from 7.1 to 8.4.
