- 1). Decide how you want to run your PHP code. If you have a PHP server, you can execute code using PHP files. If you don't have access to a PHP server, you can use an online PHP interpreter. Enter the code in this tutorial into either a PHP file or the online PHP interpreter.
- 2). Begin your PHP program with the following statement:
<?php - 3). Declare a string variable and assign it some text value. This text must contain leading and trailing extraneous spaces. For example, you can write the following:
$text = " extra spaces "; - 4). Trim the text by passing the "$text" variable to the "trim" function. Save the resulting trimmed string into another variable, like this:
$trimmedText = trim($text); - 5). Print the values held by each string using the following three print statements; the middle statement just prints a blank line between outputs:
print($text);
print("\n");
print($trimmedText); - 6). Conclude your PHP program with the statement below. Your program is now ready to be tested on your PHP server or online PHP interpreter.
?> - 7). Execute the program. The output should look like this:
extra spaces
extra spaces
