How do you get information from a form that is submitted using the "get" method?
-
Request.QueryString;
-
Request.Form;
-
$_GET[];
Correct Answer
A. $_GET[];Explanation
When a form is submitted using the "get" method, the data entered in the form is appended to the URL as query parameters. To retrieve this data in the server-side code, we can use the $_GET[] superglobal array in PHP. This array contains key-value pairs, where the keys are the names of the form fields and the values are the data entered by the user. By accessing the appropriate key in the $_GET[] array, we can retrieve the information submitted in the form.Rate this question:

In PHP you can use both single quotes ( ' ' ) and double quotes ( " " ) for strings:
-
False
-
True
Correct Answer
A. TrueExplanation
In PHP, you can indeed use both single quotes ( ' ' ) and double quotes ( " " ) for strings. This flexibility allows developers to choose the most suitable option based on their specific needs. Single quotes are generally preferred when there are no variables or escape sequences within the string, as they are slightly faster and do not require parsing. Double quotes, on the other hand, allow for variable interpolation and the inclusion of special characters using escape sequences.Rate this question:

VBScript
-
Perl and C
-
JavaScript
Correct Answer
A. Perl and CExplanation
The PHP syntax is most similar to Perl and C because PHP borrowed many of its syntax and features from these two languages. Like Perl, PHP uses a combination of procedural and object-oriented programming styles, and it supports regular expressions and a wide range of built-in functions.
