PHP Developer Toolkit

BY TOOLS.FUN  ·  MARCH 28, 2026  ·  5 min read

PHP powers a massive share of the web — from WordPress and Laravel to Symfony and custom e-commerce platforms. Daily tasks like formatting JSON API responses, debugging URL-encoded form data, and testing regex patterns eat into productive coding time. These free, browser-based tools handle the repetitive work so you can focus on building features.

JSON Formatter & Validator

Paste the output of json_encode() or an incoming webhook payload to pretty-print and validate it instantly. Catches the subtle errors — trailing commas, unescaped characters — that cause json_decode() to return null.

Best for: debugging Laravel API resources, validating WordPress REST API responses, inspecting WooCommerce webhook payloads.

RegExp Tester

PHP's PCRE engine is feature-rich but easy to get wrong. Test patterns with live highlighting before embedding them in preg_match() or preg_replace(). Saves the tedious edit-refresh-var_dump cycle.

Base64 Encoder / Decoder

Decode Base64-encoded email attachments, JWT tokens, or base64_encode() output. Encode binary data for inline images in HTML emails sent via PHPMailer or Laravel Mail.

URL Encoder / Decoder

Decode percent-encoded strings from $_GET parameters or encode special characters for safe use in query strings. Prevents double-encoding bugs that plague redirect flows and OAuth callbacks.

Code Diff Tool

Compare two PHP files, composer.lock changes, or Blade template versions side by side. Faster than a git diff when reviewing plugin updates or theme customizations.

JSON to XML Converter

Legacy integrations, payment gateways, and SOAP services still require XML. Convert JSON to well-formed XML when bridging modern Laravel APIs with older enterprise systems.

MD5 / Hash Generator

Generate MD5 and SHA-256 hashes to verify file integrity, test hash() output, or debug HMAC-based webhook signature validation in your controllers.

Best for: verifying Stripe webhook signatures, debugging WordPress password hashes, checking file checksums.

Crontab Calculator

Validate cron expressions for Laravel's task scheduler or direct crontab entries. See the next ten execution times in plain English — no more guessing when schedule:run will fire.

Timestamp Converter

Convert Unix timestamps to readable dates and back. Essential when debugging time() and strtotime() values, reading MySQL UNIX_TIMESTAMP() output, or correlating log entries.

Password Generator

Generate strong random passwords for database credentials, APP_KEY values, and service-account tokens. Copy directly into your .env file.

AES Encryptor

Test AES encryption to verify your openssl_encrypt() implementation. Useful when debugging Laravel's encrypted cookies or building custom encryption for stored credentials.

Color Converter

Convert HEX to RGB or HSL when building WordPress themes, customising Blade templates, or matching design tokens to CSS variables. No need for a separate design application.

QR Code Generator

Generate QR codes for URLs, authentication setup, or marketing campaigns directly in the browser. Useful for two-factor authentication setup pages and printed event materials.

Best for: generating 2FA provisioning QR codes, creating links for printed marketing materials.
