How do you define a constant in PHP?
You can define a constant using the define() directive.you can use this a number of ways;to define a variable to a constant do:$string = "hello";define("string",$string);to define a string to a constant use:define("hello","there");to define a integer or other numerical value use:define("number",1.0);Summery:to define a string use quotes as you would do a string.Unlike variables in PHP a constant cannot be changed or undefined once it is defined. Constant remains automatically globally throughout the script. It means that it can be accessed from inside a function. e.g.
What is slope of 0?
if you define y = constant then the slope of any constant is 0 so if you define the line y = 0 the slope of 0 is 0.
Define constant and variable?
Constant means that it never changes. Variable means that it could, and likely will change. There are 24 hours in a day, so that is a constant. The weather is variable, so it could be cloudy, rainy, windy, or sunny.
Define manipulated responding and controlled variables?
the controlled variables are the factors that are kept constant during an experiment. if they are not kept constant then they may affect the outcome of the experiment. the manipulated variable is the factor that is different between the experiment and the control. the responding variable is the variable that is being measured in the experiment.
Does a spiral staircase have a constant slope?
Previous answer: "No because the line is not straight and the points of the slop is in different ares." The above is ambiguous. You need to define the term slope. The slope of a helix (or any curve) is normally defined as the slope of a line that is tangent to the helix (curve). And then you need to define, slope with respect to what? Normally that would be slope with respect to a horizontal plane. That slope, by definition, is constant for a helix with a vertical axis. The value of the slope of such a helix is pitch / (2*pi*R), where R is the radius from the axis. Then you have to consider where on the staircase you are. A staircase is not a single helix. It has width, or different radii. If you are walking up stairs at a constant radius R from the axis (on a helix), then the slope is constant. In any case, the average slope of the stairs varies with the radius R on which you are walking, so that would not be a constant.

How would you declare a constant of 5 called MYCONST?
A constant of 5 called MYCONST would be declared as #define MYCONST 5. This is because the statement used is a define statement.
What is slope of 0?
if you define y = constant then the slope of any constant is 0 so if you define the line y = 0 the slope of 0 is 0.
Define a specific rate constant?
The specific rate constant a proportionally determined constant that is usually different for various reactions with changes in temperature.
What is the annual mortgage constant for a 10 percent loan with a 25 year amortization?
Please define what you mean by "constant". Thank You!
How do you declare constant in Turbo C?
In C there is no constant with a name. It is done with the preprocessor directive of #define as in #define pi 3.1416 The preprocesor substitutes every occurance of word pi (with blanks on either side) with 3.1416
Write a preprocessor directive to accomplish Define symbolic constant YES to have the value 1?
I'm not exactly sure that this is a question, but here you are:#define YES 1
Define capacitive time constant in terms of charging and discharging?
The product of resistance and capacitance is referred to as the time constant. It determines rate of charging and discharging of a capacitor.
Pi is a mathematical constant related to circle define Pi?
Ratio of the perimeter of a circle (circumference) to its diameter
Define constant and variable?
Constant means that it never changes. Variable means that it could, and likely will change. There are 24 hours in a day, so that is a constant. The weather is variable, so it could be cloudy, rainy, windy, or sunny.
Define constant returns to scale?
My loose definition of constant returns to scale:Constant returns to scale occur when a given increase in output is brought about by the same proportional increase in returns.
How do you declare a constant?
use: define("GREETING", "Hello you.", true); 1st parameter is the name for your constant 2nd parameter is the value of that constant 3rd parameter is whether or not you want the constant to be case-insensitive. Default is case sensitive. http://php.net/manual/en/function.define.php
