Here’s a round-up of most common 10 PHP interview questions which will help you sail through a tight interview session. Get started:
It is used for printing a data in the webpage.
For an instance, <?php echo ‘Car insurance'; ? >, is the code to print a text on the webpage.
The former is used to kill a variable, while the later is used to destroy a file.
With the help of GET method, we send 1024 bytes, while POST method transfers a huge bulk of data. Also, the latter is more secure a method than GET.
The major point of difference between the two is that the sessions are stored on the server, while cookies are kept inside a user’s computer in text file format. The specialty of session is to hold multiple variables as the cookies fail to hold multiple variables.
Its simple, enter Setcookie(“sample”, “ram”, time()+3600);
The sole purpose of this function is to detect if a variable is set or not, or whether it is NULL.
Generating random numbers in PHP is done using the rand() function – it generates numbers all within a given range.
To do this, use the code header(“Location:index.php”);.
Follow this way:
var $arr = array(‘Php’, ‘java’, ‘ruby’)
The main purpose of enctype attribute is to determine how the form-data is to be encoded while submitting it to the server. We need to set enctype as “multipart/form-data” at the time of uploading files.
