PHP is used to create HTML, Javascript and in some cases, CSS code. If you need to use a scripting language, such as PHP, once the page has been loaded into the browser, then you must either refresh the page or use Ajax to request more processing at the server side.
Similarly, you may ask, how is JavaScript different from PHP?
While JS is used for client side scripting (except in node.js) and PHP is used for server side scripting. Simply, JavaScript codes are executed by your web browser, like the catchy animations or simple calculations . Your browser does all the processing. While PHP runs on the server, where your webpage is stored.
Are PHP and JavaScript similar?
While JS is used for client side scripting (except in node.js) and PHP is used for server side scripting. Simply, JavaScript codes are executed by your web browser, like the catchy animations or simple calculations . It is not hard at all to learn JavaScript or PHP. All the arithematic operators are same.
Is it easy to learn PHP?
HTML is a markup language. As far as which is easier to learn, HTML is definitely easier. The path that I would recommend for learning web development would be to learn HTML, CSS and JavaScript and then learn Node.js or Python or PHP.
Can you use PHP and Javascript together?
Generally speaking, you will have a .php file on your server. That PHP file will generate an HTML page — which may contain Javascript code. Once the HTML page is received by the browser, it will be displayed, and Javascript will be executed. php can’t work in an html file.

Why do we use in Javascript?
JavaScript is most commonly used as a client side scripting language. This means that JavaScript code is written into an HTML page. When a user requests an HTML page with JavaScript in it, the script is sent to the browser and it’s up to the browser to do something with it.
How do you define a constant?
A constant is an identifier (name) for a simple value. The value cannot be changed during the script. A valid constant name starts with a letter or underscore (no $ sign before the constant name). Note: Unlike variables, constants are automatically global across the entire script.
What is the main difference between Javascript and HTML?
HTML is a static markup language which you can’t do anything dynamic just by using its tags. JavaScript is a scripting language that is not only used with HTML/CSS, but also can be used to do other things not related to web or HTML/CSS.
What is the difference between HTML and PHP?
HTML is a language used to describe to a browser how to display text and other objects in a browser window. It is not a programming language. HTML works on a client computer (the system on which the page is being viewed). PHP is a scripting language, and can be used to create web pages written in HTML.
What is the universal logic gate?
A universal gate is a gate which can implement any Boolean function without need to use any other gate type. The NAND and NOR gates are universal gates. In practice, this is advantageous since NAND and NOR gates are economical and easier to fabricate and are the basic gates used in all IC digital logic families.
What is the propagation delay of a logic gate?
In computer networks, propagation delay is the amount of time it takes for the head of the signal to travel from the sender to the receiver. It can be computed as the ratio between the link length and the propagation speed over the specific medium.
What is the processing delay?
Processing delay is a key component in network delay. During processing of a packet, routers may check for bit-level errors in the packet that occurred during transmission as well as determining where the packet’s next destination is.
What is fan in of a logic gate?
Fan-in is the number of inputs a logic gate can handle. For instance the fan-in for the AND gate shown in the figure is 3. Physical logic gates with a large fan-in tend to be slower than those with a small fan-in. This is because the complexity of the input circuitry increases the input capacitance of the device.
What is Noise Margin in digital circuits?
In electrical engineering, noise margin is the amount by which a signal exceeds the minimum amount for proper operation. It is commonly used in at least two contexts: In a digital circuit, the noise margin is the amount by which the signal exceeds the threshold for a proper ‘0’ or ‘1’.
Can CMOS drive TTL?
In the LOW state, a TTL output can drive CMOS directly. However, the guaranteed TTL HIGH output level of 2.4 volts is not a valid input level for CMOS. If the TTL output drives only CMOS inputs, then essentially no current is drawn and the HIGH output may be 3.5 V or higher.
Is CMOS or TTL faster?
CMOS compared to TTL: CMOS circuits do not draw as much power as TTL circuits while at rest. However, CMOS power consumption increases faster with higher clock speeds than TTL does.
What is meant by TTL logic?
Transistor-transistor logic (TTL) is a digital logic design in which bipolar transistor s act on direct-current pulses. Many TTL logic gate s are typically fabricated onto a single integrated circuit (IC). A TTL device employs transistor s with multiple emitters in gates having more than one input.
What is RTL logic?
Resistor–transistor logic (RTL) is a class of digital circuits built using resistors as the input network and bipolar junction transistors (BJTs) as switching devices.
What is ECL logic?
In electronics, emitter-coupled logic (ECL) is a high-speed integrated circuit bipolar transistor logic family. ECL uses an overdriven BJT differential amplifier with single-ended input and limited emitter current to avoid the saturated (fully on) region of operation and its slow turn-off behavior.
What is TTL and ECL?
Emitter Coupled Logic (ECL), also referred to as Current Mode Logic families, is a digital technology with extremely high-speed. Transistors are not allowed to go into deep saturation thus, eliminating storage delays like in TTL logic families. Transistors are driven either in cut off or in active region.
What is a logic family?
A logic family of monolithic digital integrated circuit devices is a group of electronic logic gates constructed using one of several different designs, usually with compatible logic levels and power supply characteristics within a family. Some such logic families use static techniques to minimize design complexity.
How hard is it to learn PHP?
PHP is not hard then other programming languages if you have learned any other language like html, javascript, SQL, cases before PHP so you can easily learn it. It is a server side scripting language which offers the create a static and dynamic websites. It is easy to learn but has a rich set of applications.
