Analyse PHP code with PHPStan

Analyse PHP code using the PHPStan playground API at https://api.phpstan.org/analyse. This runs PHPStan across PHP versions 7.2–8.5 and returns errors for each version.

The code to analyse: $ARGUMENTS

Step 1: Prepare the code

Get the PHP code to analyse. If $ARGUMENTS is a file path, read the file contents. The code must start with <?php.

Step 2: Determine settings

Unless the user specified otherwise, use these defaults:

• level : "10" (strictest)
• strictRules : false
• bleedingEdge : false
• treatPhpDocTypesAsCertain : true

If the user asked for strict rules or bleeding edge, set those to true.

Step 3: Call the playground API

Submit the code via POST:

curl -s -X POST 'https://api.phpstan.org/analyse' \
  -H 'Content-Type: application/json' \
  -d '{
    "code": "<PHP code, JSON-escaped>",
    "level": "<level>",
    "strictRules": <true|false>,
    "bleedingEdge": <true|false>,
    "treatPhpDocTypesAsCertain": <true|false>,
    "saveResult": true
  }'

The code value must be properly JSON-escaped (escape quotes, backslashes, newlines).

Step 4: Parse the response

The response JSON contains:

• versionedErrors — array of objects, one per PHP version, each with:
  • phpVersion — integer encoding: e.g. 80400 = PHP 8.4, 70400 = PHP 7.4
  • errors — array of error objects with message, line, identifier, tip (optional), ignorable
• id — UUID for the saved result

Convert phpVersion integers to readable strings: Math.floor(v / 10000) . Math.floor((v % 10000) / 100).

Step 5: Present results as markdown

Output the results in this format:

Settings used

Level: <level> | Strict rules: yes/no | Bleeding edge: yes/no

Errors

Group consecutive PHP versions that have identical errors (same messages, lines, and identifiers) into ranges. For example, if PHP 7.2–8.3 all report the same errors, show them as one group.

If all PHP versions report identical errors, show a single group:

All PHP versions (no differences):

If errors differ across versions, show separate groups:

PHP 8.0 – 8.5:

PHP 7.2 – 7.4:

No errors.

If there are no errors on any PHP version, say: No errors found on any PHP version.
