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
$string = "w3wiki!!";
// Printing the string directly
echo ("Printing the string: ");
// Printing the variable
echo $string;
?>
Output
Printing the string: w3wiki!!
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
// 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
$string = "w3wiki!!";
// Printing the string directly
print("Printing the string: ");
// Printing the variable
print $string;
?>
Output
Printing the string: w3wiki!!
Example 2: Arrays can be printed using the print_r method which is used to print the index along with its values.
<?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 )
Using sprintf()
To display formatted text in PHP, use printf() or sprintf(). Provide a format string with placeholders for variables, followed by the variables themselves. printf() prints directly to the output, while sprintf() returns the formatted string.
Example
<?php
$string = "w3wiki!!";
// Creating the formatted string using sprintf
$formattedString = sprintf("Printing the string: %s", $string);
// Printing the formatted string
print $formattedString;
?>
Output:
Printing the string: w3wiki!!
