What is the break statement used for in PHP?

  • Terminating the execution of a loop or switch statement
  • Skipping the current iteration of a loop
  • Returning a value from a function
  • Displaying an error message

How do you use Regular Expressions in PHP?

  • By using the preg_match() function to match a pattern against a string.
  • By using the rand() function to generate random numbers.
  • By using the str_replace() function to replace occurrences of a substring in a string.
  • By using the sizeof() function to determine the size of an array.
In PHP, you can use regular expressions by using the preg_match() function to match a pattern against a string. The preg_match() function takes two parameters: the pattern to match and the string to search. It returns true if the pattern is found in the string and false otherwise. Regular expressions are defined using special characters and modifiers that specify the pattern to search for. The preg_match() function allows you to perform various operations based on the matched pattern, such as extracting data or validating input. Learn more: https://www.php.net/manual/en/book.regex.php

In PHP, the fopen() function with 'w' as the mode will create a file if it doesn't exist and open it for ______.

  • reading
  • writing
  • appending
  • deleting
In PHP, using the 'w' mode with the fopen() function allows you to create a file if it doesn't exist and open it for writing. This mode truncates the file if it already exists, so caution should be exercised.

How do you define an abstract class in PHP?

  • abstract class ClassName
  • class ClassName
  • interface ClassName
  • final class ClassName
To define an abstract class in PHP, you use the abstract keyword followed by the class keyword and the name of the class. For example: abstract class ClassName. This indicates that the class is intended to be an abstract class. Abstract classes can have abstract methods as well as non-abstract methods. Remember that abstract methods are declared but not implemented in the abstract class itself and must be implemented in the child classes that inherit from the abstract class. To learn more, see: http://php.net/manual/en/language.oop5.abstract.php

Which of the following are ways to open a file in PHP?

  • open() and read()
  • fopen() and fread()
  • include() and require()
  • file_open()
The correct way to open a file in PHP is by using the fopen() function. It takes the path to the file and the mode as parameters. This function returns a file handle or pointer that can be used for file operations. The other options mentioned are not valid for opening files in PHP.

You need to use inheritance in your PHP script. How would you do this?

  • By using the extends keyword
  • By using the implement keyword
  • By using the inherit keyword
  • By using the derive keyword
In PHP, to use inheritance in your script, you would use the extends keyword followed by the name of the parent class. The correct option is "By using the extends keyword." By extending a class, you create a subclass that inherits properties and methods from the parent class. For further details, refer to the PHP documentation on class inheritance: http://php.net/manual/en/language.oop5.inheritance.php

In PHP, the foreach loop can only access the values of an array, not the keys.

  • Index
  • Element
  • Key
  • Value
In PHP, the foreach loop allows you to access both the keys and values of an array. During each iteration, you can use the "key" variable to access the key/index of the current element, and the "value" variable to access the value of the element. This allows you to work with both the keys and values simultaneously. The foreach loop provides a convenient way to iterate over arrays and perform operations on each element.
