Valitron Issues Fixed

Valicomb is a modernized fork of vlucas/valitron. This page documents known issues from the original library that have been fixed in Valicomb.

Critical Fixes

These issues caused incorrect validation results or PHP errors in the original library.

Empty Strings Pass Integer Validation

Fixed Valitron #368

Problem: Empty strings incorrectly passed the integer validation rule.

// In Valitron - BUG: This passes validation
$v = new Validator(['num' => '']);
$v->rule('integer', 'num');
$v->validate(); // true (incorrect!)

Fix: Valicomb uses filter_var() with FILTER_VALIDATE_INT which correctly rejects empty strings.

// In Valicomb - This correctly fails
$v = new Validator(['num' => '']);
$v->rule('integer', 'num');
$v->validate(); // false (correct!)

Empty Strings Pass Length Validation

Fixed Valitron #356

Problem: Empty strings incorrectly passed lengthMin and lengthBetween validation rules.

// In Valitron - BUG: This passes validation
$v = new Validator(['text' => '']);
$v->rule('lengthMin', 'text', 1);
$v->validate(); // true (incorrect!)

Fix: Valicomb correctly calculates string length and compares against the minimum.

// In Valicomb - This correctly fails
$v = new Validator(['text' => '']);
$v->rule('lengthMin', 'text', 1);
$v->validate(); // false (correct!)

Empty Arrays Pass Required Validation

Fixed Valitron #260

Problem: Empty arrays incorrectly passed the required validation rule.

// In Valitron - BUG: This passes validation
$v = new Validator(['items' => []]);
$v->rule('required', 'items');
$v->validate(); // true (incorrect!)

Fix: Valicomb now treats empty arrays as empty values that fail required validation.

// In Valicomb - This correctly fails
$v = new Validator(['items' => []]);
$v->rule('required', 'items');
$v->validate(); // false (correct!)

// Non-empty arrays still pass
$v = new Validator(['items' => ['apple', 'banana']]);
$v->rule('required', 'items');
$v->validate(); // true (correct!)

PHP 8.1+ strtotime() Deprecation Warnings

Fixed Valitron #381 #370 #357

Problem: PHP 8.1+ throws deprecation warnings when null is passed to strtotime().

// In Valitron - PHP 8.1+ deprecation warning
Deprecated: strtotime(): Passing null to parameter #1 ($datetime) of type string is deprecated

Fix: Valicomb validates input types before calling strtotime() and uses explicit string casts.

// In Valicomb - No deprecation warnings
// All strtotime() calls are protected with type checks
if (!is_string($value)) {
    return false;
}
// Or use explicit casting
$timestamp = strtotime((string)$value);

Array Validation on Non-Arrays Causes Warnings

Fixed Valitron #182

Problem: Using array validation rules on non-array values caused PHP warnings.

// In Valitron - BUG: PHP Warning
$v = new Validator(['field' => 'not an array']);
$v->rule('array', 'field');
$v->validate(); // Warning: Invalid argument supplied for foreach()

Fix: Valicomb checks input types before performing array operations.

// In Valicomb - Clean failure, no warnings
$v = new Validator(['field' => 'not an array']);
$v->rule('array', 'field');
$v->validate(); // false (no warnings!)

Validation Logic Improvements

Min Validation with Zero Values

Fixed Valitron #70

Problem: The value 0 was sometimes incorrectly handled in min/max validation due to PHP’s type juggling.

Fix: Valicomb uses is_numeric() checks and high-precision bccomp() for numeric comparisons.

URL Validation with Non-String Input

Fixed Valitron #273

Problem: URL validation threw errors when the input was an object instead of a string.

Fix: Valicomb validates input types before processing, returning false for non-string values.
