1Which PHP tag style is the only one always available regardless of php.ini configuration?

A.<? ... ?>

B.<% ... %>

C.<?php ... ?>

D.<script language="php"> ... </script>

Explanation: The standard <?php ... ?> tag is the only opening tag guaranteed to work in every PHP installation. Short tags <? ?> depend on the short_open_tag setting, ASP-style <% %> tags were removed in PHP 7.0, and the <script language="php"> form was removed in PHP 7.0.

2What does the following code output? <?php var_dump(0 == 'abc'); ?>

A.bool(true)

B.bool(false)

C.int(0)

D.Fatal error

Explanation: Since PHP 8.0, comparing a number with a non-numeric string converts the number to a string and performs a string comparison. So 0 == 'abc' compares '0' with 'abc' and returns false. (Prior to PHP 8 it returned true.)

3Which value is NOT considered falsy when cast to a bool in PHP?

A.0

B.'0'

C.'false'

D.[]

Explanation: The string 'false' is truthy because any non-empty string other than '0' evaluates to true. Falsy values include 0, 0.0, '', '0', null, [], and the special false value. Note that 'false' as a string is not in that list.

4What does this code print? <?php $x = '5 apples'; $y = $x + 3; var_dump($y); ?>

A.int(8) with no warning

B.int(8) and a deprecation/warning notice

C.string(7) "5 apples3"

D.TypeError

Explanation: PHP 8 still produces 8 because the leading numeric part of '5 apples' is converted to 5, but a non-numeric string warning is emitted. In PHP 7 a Notice was raised; in PHP 8 it became a Warning, and a fully non-numeric string would throw a TypeError under strict_types only when explicitly required.

5Which of these is the correct way to declare strict typing in PHP?

A.use strict;

B.declare(strict_types=1);

C.strict_types = true;

D.ini_set('strict_types', 1);

Explanation: declare(strict_types=1); must be the very first statement in a file. It causes scalar type declarations on parameters and return types to be enforced strictly within that file rather than coerced.

6Which loop construct is guaranteed to execute its body at least once?

A.for

B.while

C.do-while

D.foreach

Explanation: do-while evaluates its condition after each iteration, so the body always runs at least once. for, while, and foreach all evaluate their condition (or array length) before the first iteration.

7What does the match expression return? <?php $x = 1; $r = match($x) { '1', 1 => 'a', default => 'b', }; echo $r; ?>

A.a

B.b

C.Fatal error: duplicate match arm

D.Notice and 'a'

Explanation: match uses strict (===) comparison, but multiple values in an arm are tried in order. Since 1 === 1 matches, the result is 'a'. The string '1' is also a valid arm value and does not conflict because match arms are not deduplicated.

8Which feature was introduced in PHP 8.0?

A.Enums

B.Readonly properties

C.Named arguments

D.Property hooks

Explanation: Named arguments were introduced in PHP 8.0 along with match, the nullsafe operator (?->), constructor property promotion, and union types. Enums and readonly properties came in 8.1; property hooks came in 8.4.

9What is the value of $x? <?php $x = 10 % 3; ?>

A.1

B.3

C.0.3333

D.3.3333

Explanation: The % operator returns the integer remainder of a division. 10 / 3 is 3 remainder 1, so 10 % 3 is 1.

10Which operator is the null coalescing assignment operator?

A.??

B.??=

C.?:

D.?->=

Explanation: ??= is the null coalescing assignment operator: $a ??= $b is equivalent to $a = $a ?? $b. It assigns only when $a is null or undefined.

About the Zend PHP Certified Engineer (ZCPE) Exam

The Zend PHP Certified Engineer (ZCPE) is the long-standing industry credential for professional PHP developers. The exam validates fluency with the modern PHP language - syntax, types, control flow, functions and closures, OOP (classes, interfaces, traits, enums, attributes, readonly), data formats (JSON, XML, dates), web features (sessions, cookies, headers, file uploads), security (SQL injection, XSS, CSRF, password_hash), I/O and streams, strings and PCRE, databases and PDO, arrays, and error/exception handling. Coverage tracks current PHP 8.x including PHP 8.4 features such as property hooks, asymmetric visibility, and new without parens.

Zend PHP Certified Engineer (ZCPE) Study Tips from Top Performers

1Memorize signatures and return types for the most-tested function families: array_*, str_*, preg_*, file_*, json_*, password_*, hash_*

2Master PHP 8.x features that show up disproportionately: enums (from/tryFrom), readonly, attributes (#[...]), named args, match (vs switch), first-class callable syntax, nullsafe

3Drill the strict_types contract: under declare(strict_types=1), what coerces and what TypeErrors? Practice with int, float, string, bool

4Practice security scenarios: PDO prepared statements (named vs positional), password_hash + password_verify, hash_equals for HMAC, session_regenerate_id on login

5Review the Throwable hierarchy: Exception and Error both implement Throwable - Error is NOT a subclass of Exception

6Get fluent with array operations: sort vs asort vs ksort vs usort, array_merge vs +, list/destructuring with associative arrays

7Learn the difference between session.use_strict_mode and session.use_only_cookies - both matter for fixation defense

8Practice fill-in questions: typing exact function names, exact return values, and exact INI keys (no autocomplete in the exam)

Frequently Asked Questions

What is the Zend PHP Certified Engineer (ZCPE) exam?

The ZCPE is a vendor-neutral PHP language certification from Perforce Zend. It validates professional-level command of the PHP language - syntax, types, OOP, functions, data formats, web features, security, I/O, strings, databases, arrays, and error handling. Coverage tracks current PHP versions and includes PHP 8.x features through PHP 8.4.

How many questions are on the ZCPE exam?

The exam has approximately 70-75 questions delivered in 90 minutes with a 70% passing score. Question types include single-answer multiple choice, multiple-answer multiple choice, and free-form fill-in (you type the answer). It is closed-book - no notes, IDE, or php.net access during the exam.

How much does the Zend PHP exam cost?

The ZCPE exam costs approximately $195 USD. It is delivered through Pearson VUE testing centers or as an online proctored session. Retakes require the full fee. There is no separate exam-objective document fee, and PHP.net is the canonical free reference for study.

Which PHP version does the current ZCPE exam test?

As of April 2026 the exam covers through PHP 8.4. Although PHP 8.5 was released in November 2025, the certification body typically lags one minor version. PHP 8.4 features tested include property hooks, asymmetric visibility, new without parens, and lazy objects. Earlier PHP 8.x features - enums, readonly, attributes, named args, match, nullsafe, first-class callable - are also fair game.

How long should I study for the ZCPE?

Plan for 60-120 hours over 6-12 weeks if you have 2+ years of PHP experience. Start with the language reference on php.net, then drill OOP, security, and PDO. The closed-book format means you must memorize function signatures, return types, and constants. Aim for 85%+ on full-length practice exams before scheduling.

Is ZCPE worth it in 2026?

Yes - PHP still powers ~75% of the web (WordPress, Drupal, Magento, Laravel apps), and ZCPE is the only widely recognized vendor-neutral PHP credential. It signals language fluency to employers in CMS, e-commerce, and SaaS shops. Senior PHP roles often list ZCPE as a plus, and the credential pairs well with Acquia, Magento, or Laravel certifications.

What jobs can I get with ZCPE?

ZCPE supports roles including PHP Developer, Senior PHP Engineer, Backend Developer, Drupal/WordPress/Magento Developer, Laravel Developer, and Full-Stack PHP Engineer. US salaries typically range $85K-$145K depending on seniority and stack (Laravel, Symfony, Drupal). The credential is particularly valuable for consultants and freelancers needing third-party validation of PHP skills.
