CurlHeaderOptionRequiresArray ​

error native on by default

Group: Probable bugs

Identify curl_setopt HTTPHEADER option with a value proven scalar rather than array; curl_setopt_array requires exact option-map extraction.

Detection ​

  • Report curl_setopt HTTPHEADER option with a value proven scalar rather than array; curl_setopt_array requires exact option-map extraction.
  • Resolve builtin functions, classes, constants and methods, including imports and supported named arguments. Follow only bounded local facts within one lexical scope. Receiver and argument provenance must establish the specific API contract; variable names and comments never prove intent.
  • Report one finding per violating operation. A reachable path, unchanged value identity and applicable API behavior are required. Intervening mutation, unknown calls involving tracked values or escaped aliases invalidate proof. When the proof is inconclusive, nothing is reported.

Exceptions (no report) ​

  • Exclude unresolved required symbols, user-defined lookalikes, incomplete syntax, unknown required values and unsupported versions.
  • Both @custos-ignore CurlHeaderOptionRequiresArray and @noinspection CurlHeaderOptionRequiresArray suppress this native rule.

Fix ​

None. A repair requires a semantic decision or application error-handling policy.

PHP versions ​

Available in PHP 5.3–8.5 where the referenced API exists. Do not apply extension contracts when the resolved API is unavailable. Gate syntax and version-specific behavior to the configured target.

Configure ​

In custos.json:

json
{
  "rules": {
    "CurlHeaderOptionRequiresArray": {
      "enabled": false
    }
  }
}

Suppress ​

Before the statement or declaration (or the first statement of the file):

php
// @custos-ignore CurlHeaderOptionRequiresArray
