PackFormatArgumentMismatch

warning native on by default

Match pack values to the format.

Example

php

<?php
$bytes = pack('N2', 11);

Reported:

Parse a constant pack format and report missing required value arguments. Numeric directives consume their repeat counts, string directives consume one value, and padding/position directives consume none. Supported numeric directives are c, C, s, S, n, v, i, I, l, L, N, V, q, Q, J, P, f, g, G, d, e and E. String directives are a, A, Z, h and H; cursor directives are x, X and @. Star counts consume remaining arguments; unknown/unpacked arguments invalidate count proof. Do not report extra arguments here. Exclude q, Q, J and P before PHP 5.6 and g, G, e and E before PHP 7.0; exclude Z before PHP 5.5. Unknown format directives invalidate proof.
Resolve builtin functions, extension classes, constants and method receivers, including aliases and supported named arguments. Inspect reachable operations in one lexical scope with bounded local flow.
Emit one finding per violating operation. Never infer policy from names or comments. When the proof is inconclusive, nothing is reported.

Exclude shadowed or unresolved symbols, incomplete code, unknown required constants, ambiguous receiver identity and unsupported versions. Reassignment, escaping aliases, and unknown calls invalidate dependent flow facts.
Both @custos-ignore PackFormatArgumentMismatch and @noinspection PackFormatArgumentMismatch suppress this native rule.

None. A safe repair requires choosing values, error handling, or application behavior.

Apply throughout PHP 5.3–8.5 only where the extension API and syntax exist. Do not flag API unavailability through this rule.

None. Use normal rule configuration to enable or disable the inspection.
