To access an element of an associative array in PHP, you use the name of the array followed by the ______ of the element in square brackets.

  • Key

You are debugging a PHP script and a variable is not retaining its value between function calls. What might be the problem and how would you solve it?

  • The variable is declared as a local variable inside the function.
  • The variable is declared with the static keyword inside the function.
  • The variable is declared as a global variable outside of any function.
  • The variable is not properly initialized or assigned values.
If a variable is not retaining its value between function calls, the possible problem might be that the variable is declared with the static keyword inside the function. The static keyword makes the variable retain its value between multiple calls to the same function. To solve this, you can remove the static keyword if the variable doesn't need to retain its value. Alternatively, if the variable should retain its value, make sure it is properly initialized and assigned values.

You need to extract a part of a string in your PHP script. How would you do this using Regular Expressions in PHP?

  • Use the preg_match() function with capturing groups in the Regular Expression pattern.
  • Use the strtolower() function to convert the string to lowercase.
  • Use the substr() function to extract the desired part of the string.
  • Use the is_string() function to check if the value is a string.
To extract a part of a string using Regular Expressions in PHP, you can use the preg_match() function with capturing groups in the Regular Expression pattern. By defining capturing groups within the Regular Expression pattern, you can specify the part of the string you want to extract. When a match is found, the preg_match() function will populate an array with the captured groups. You can then access the desired part of the string using the appropriate index in the array. This allows you to extract specific portions of a string based on a pattern defined by a Regular Expression. Learn more: https://www.php.net/manual/en/function.preg-match.php

This function is useful when you need to validate the numeric nature of a variable. Learn more: https://www.php.net/manual/en/function.is-numeric.php
