Security analysis Complexity analysis Duplicate-line estimate Auto-run while typing

It calculates line and declaration metrics, estimates nesting and complexity, flags code smells, and combines category scores into an overall rating.

Metrics → smell rules → security rules → category scores → weighted overall score → prioritized recommendations.

Metrics are estimates. They are useful for triage and comparison but do not replace dedicated static-analysis platforms or human code review.

Input: a deeply nested function using eval.

Output: security, nesting, parameter-count, and maintainability findings.

How can I measure PHP code complexity online?

Run the inspector to estimate nesting, branching, function size, and parameter counts.

How do I find code smells in a PHP file?

The inspector flags long methods, deep nesting, too many parameters, magic numbers, globals, empty catches, and related patterns.

How can I calculate PHP maintainability score?

The tool combines maintainability, readability, complexity, security, and documentation subscores with published weights.

How do I detect long methods and deep nesting in PHP?

Set the long-method threshold and enable complexity analysis.

How can I inspect PHP code for security risks?

Enable security analysis to flag risky execution, serialization, input, hashing, SQL, and file-path patterns.
