How to display text with a PHP script ?
PHP allows us to display the text in various formats using various inbuilt methods.
Using echo command: The echo command can be used to display text, including numerical, strings and arrays.
Example 1:
PHP
<?php $string = "zambiatek!!"; // Printing the string directly echo ("Printing the string: "); // Printing the variable echo $string; ?> |
Output
Printing the string: zambiatek!!
Example 2: Arrays can’t be printed directly into the script. It is compatible for displaying the data stored in string format. Therefore, the json_encode() method is used to simulate array to string conversion.
PHP
<?php // Declaring an array $arr = array(1, 2, 3, 4, 5); echo('Array : '); // Printing array echo(json_encode($arr)); ?> |
Output
Array : [1, 2, 3, 4, 5]
Using print command: The run time of the print function in PHP is slightly more than that of echo function.
Example 1:
PHP
<?php $string = "zambiatek!!"; // Printing the string directly print("Printing the string: "); // Printing the variable print $string; ?> |
Output
Printing the string: zambiatek!!
Example 2: Arrays can be printed using the print_r method which is used to print the index along with its values.
PHP
<?php // Declaring an array $arr = array(1, 2, 3, 4, 5); echo('Array : '); // Printing array print_r($arr); ?> |
Output
Array : Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 5 )
