What are common errors in PHP code that beginners often encounter?
One common error in PHP code that beginners often encounter is forgetting to properly close statements with semicolons. This can lead to syntax errors and unexpected behavior in the code. To solve this issue, always remember to end each statement with a semicolon.
// Incorrect code without semicolon
echo "Hello, World"
// Corrected code with semicolon
echo "Hello, World";
```
Another common error is using undefined variables without initializing them. This can result in notices or warnings being displayed. To fix this, make sure to initialize variables before using them.
```php
// Incorrect code using undefined variable
echo $name;
// Corrected code with variable initialization
$name = "John";
echo $name;
```
A third common error is mixing up single and double quotes in PHP strings. Using single quotes for string literals is recommended for better performance, but variables inside single quotes will not be interpolated. To resolve this, use double quotes for string interpolation.
```php
// Incorrect code with mixed quotes
$name = 'John';
echo 'Hello, $name';
// Corrected code using double quotes for interpolation
echo "Hello, $name";
