# Verify installation
php vendor/bin/package verify

Check Common Issues

### Installation Issues Section

```markdown
## Installation Issues

### Composer Install Fails

**Symptom:**

Your requirements could not be resolved to an installable set of packages.

**Solutions:**

1. **Update Composer:**
   ```bash
   composer self-update

2. Clear Composer cache:

   composer clear-cache
   

3. Check PHP version:

   php -v
   # Must be 8.4 or higher
   

4. Check required extensions:

   php -m | grep -E "json|pdo|mbstring"
   

Extension Not Found

Symptom:

PHP Fatal error: Uncaught Error: Call to undefined function json_encode()

Solution:

Install missing PHP extension:

# Ubuntu/Debian
sudo apt-get install php8.5-json

# macOS with Homebrew
brew install php@8.5

# Verify
php -m | grep json

### Configuration Issues Section

```markdown
## Configuration Issues

### Environment Variables Not Loading

**Symptom:**

API key not configured

**Checklist:**

1. **Verify `.env` file exists:**
   ```bash
   ls -la .env

2. Check variable is set:

   grep "PACKAGE_API_KEY" .env
   

3. Verify no syntax errors:

   # Values with spaces need quotes
   PACKAGE_NAME="My App Name"  # ✅ Correct
   PACKAGE_NAME=My App Name    # ❌ Wrong
   

4. Clear config cache:

   php artisan config:clear  # Laravel
   rm var/cache/config.php   # Other frameworks
   

Invalid Configuration Value

Symptom:

Configuration error: 'timeout' must be a positive integer

Solution:

Check config/package.php:

// ❌ Wrong
'timeout' => '30',  // String instead of int

// ✅ Correct
'timeout' => 30,    // Integer

### Runtime Errors Section

```markdown
## Runtime Errors

### Connection Timeout

**Symptom:**

Error: Connection timed out after 30 seconds

**Possible Causes:**

1. **Network issues** — Check connectivity
2. **Firewall blocking** — Check outbound rules
3. **Service down** — Check status page
4. **Timeout too short** — Increase timeout

**Solutions:**

```php
// Increase timeout
$client = new Client([
    'timeout' => 60,  // 60 seconds
]);

# Test connectivity
curl -v https://api.example.com/health

Rate Limit Exceeded

Symptom:

{
    "error": {
        "code": "RATE_LIMITED",
        "message": "Too many requests"
    }
}

Solutions:

1. Implement backoff:

   $client = new Client([
       'retry' => [
           'max_attempts' => 3,
           'delay' => 1000,  // ms
       ],
   ]);
   

2. Cache responses:

   $cache = new RedisCache();
   $client = new Client(['cache' => $cache]);
   

3. Upgrade plan for higher limits

Memory Limit Exceeded

Symptom:

PHP Fatal error: Allowed memory size of 134217728 bytes exhausted

Solutions:

1. Process in batches:

   foreach ($client->paginate(100) as $batch) {
       process($batch);
   }
   

2. Increase memory limit:

   ini_set('memory_limit', '256M');
   

3. Use generators:

   foreach ($client->stream() as $item) {
       yield process($item);
   }
   

### FAQ Section

```markdown
## FAQ

### General

<details>
<summary><strong>Q: What PHP version is required?</strong></summary>

PHP 8.4 or higher is required. Check your version:

```bash
php -v

Yes, the library is used in production by many projects. We follow semantic versioning and maintain backward compatibility within major versions.

Configuration

Use environment-specific .env files:

.env           # Base configuration
.env.local     # Local overrides (not committed)
.env.test      # Test environment
.env.prod      # Production environment

Yes, you can pass configuration directly:

$client = new Client([
    'api_key' => getenv('MY_API_KEY'),
]);

Performance

1. Enable caching — Reduces API calls
2. Use connection pooling — Reuse connections
3. Batch requests — Reduce round trips
4. Use async — Parallel processing

$client = new Client([
    'cache' => new RedisCache(),
    'pool_size' => 10,
]);

## Common Errors

### "Invalid API Key"

**Symptom:**

Error: Invalid API key provided

**Solutions:**
