Mastering Composer Versioning

Composer, a dependency manager for PHP, uses specific versioning rules that can sometimes be challenging to remember. This comprehensive cheatsheet is designed to help you understand and apply these rules effectively.

"require": {
    // Exact version to 1.5.4
    "vendor/package": "1.5.4",
    // Greater or lower bounds
    "vendor/package": ">=1.5.0", // Anything above 1.5.0
    "vendor/package": "<1.5.0", // Anything below 1.5.0
    
    // Wildcard
    "vendor/package": "1.5.*", // >=1.5 <1.6
    
    // Next significant release
    "vendor/package": "~1.5", // >=1.5 <2.0.0 
    "vendor/package": "~1.5.2", // >=1.5.2 <1.6.0
    
    // Next release, major version fixed
    "vendor/package": "^1.5.2", // >=1.5.2 <2.0.0 
    "vendor/package": "^0.5.2", // >=0.5.2 <0.6.0
}
