Simply reassign the value. If you have a variable $x, and you add 1 to it, you can store the value by stating $x = $x+1;
To pass PHP Variable value in Jquery simpley echo that variable : Eg <script> var jQueryVariable=<?php echo $anyVariable?> </script>
Variables in PHP do not need to be declared like some languages (e.g. JavaScript). This is all that needs to be done to assign a variable: $variable = "Value";
Maybe your speaking a variable that contains a ternary operators such as:
The preferred way is to simply alter the session superglobal. <?php $_SESSION['variable'] = "value"; ?>
Ideal thing would be to retrieve the value from PHP using AJAX and then assigning it to a java script variable. Thereafter compare it to the java script variable that is already present.
Problem with using global variables in php is that they lose the the assigned value in a different php file. They only keep the global variable value in the php file in which they are declared. Instead of globals try and use $_SESSION or $_COOKIE to keep value intact across different php files in a project
Yes as long as you change the variable of them
To print a particular value in PHP you have to select which variable you wish to print. Below is an example of how this can be done. <?php $var[1] = "Hello"; $var[2] = "Lalala"; print $var[2]; // prints Lalala but not Hello ?>
A double dollar sign in php makes a variable with a name equal to the value of the original variable. It works like this:$var = "keith";$$var = "palmer";print ($keith);// The output is: palmer
displaying a variable in php using echo statement? <?php $name="ram"; //declaring and defining the variable echo "$name"; //printing the variable using echo command ?>
In the declaration of the receiving function, you add an ampersand. <?php function myWayCoolFunction( &$params) {.....} $x = array('1','2','3'); myWayCoolFunction($x) ?>
Variables in php begin with $ and are declared by the user. $str1 = "wiki"; would store "wiki" into the variable $str1
