PHP is a server side scripting language commonly used for web applications. PHP has many frameworks and cms for creating websites.Even a non technical person can cretae sites using its CMS.WordPress,osCommerce are the famus CMS of php.It is also an object oriented programming language like java,C-sharp etc.It is very eazy for learning
It is used to print a data in the webpage, Example: <?php echo 'Car insurance'; ?> , The following code print the text in the webpage
We can include a file using "include() " or "require()" function with file path as its parameter.
If the file is not found by require(), it will cause a fatal error and halt the execution of the script. If the file is not found by include(), a warning will be issued, but execution will continue.
require() includes and evaluates a specific file, while require_once() does that only if it has not been included before (on the same page). So, require_once() is recommended to use when you want to include a file where you have a lot of functions for example. This way you make sure you don't include the file more times and you will not get the "function re-declared" error.
We can send 1024 bytes using GET method but POST method can transfer large amount of data and POST is the secure method than GET method .
Eg : var $arr = array('apple', 'grape', 'lemon');
This is not actually a real function, It is a language construct. So you can use with out parentheses with its argument list.
Example print('PHP Interview questions');
print 'Job Interview ');
in_array used to checks if a value exists in an array
count() is used to count all elements in an array, or something in an object
It's how they handle failures. If the file is not found by require(), it will cause a fatal error and halt the execution of the script. If the file is not found by include(), a warning will be issued, but execution will continue.
