Practical program exercise 8 PHP Create & Execute Echo and Print Statements for 12th computer applications
PHP Create & Execute Echo and Print Statements
echo
- The echo statement produce output fast
- It doesn’t return any value
- The echo statement produces one or more lines of output.
- The echo statement is missing the closing quotation mark.
- The instructions in this instance consisted of a call to PHP’s echo statement, which is responsible for displaying output to the user; the output to be displayed is enclosed in quotation marks.
- The print statement produce output slow
- It return the value 1
variable
- A variable is simply a container that’s used to store both numeric and non-numeric information.
- And just as with any container, you can move it from place to place, add stuff to it, or empty it out on the floor in a pile and fill it with something completely different.
Assigning Values to Variables
- Assigning a value to a variable in PHP is quite easy: use the equality (=) symbol, which also happens to be PHP’s assignment operator.
- This assigns the value on the right side of the equation to the variable on the left.
- PHP has some simple rules for naming variables.
- Every variable name must be preceded with a dollar ($) symbol and must begin with a letter or underscore character, optionally followed by more letters, numbers, or underscore characters.
- Common punctuation characters, such as commas, quotation marks, or periods, are not permitted in variable names; neither are spaces.
