Example 1

First we will show you the basic example of the PHP String chop() function to chop or remove the string from the given $string.

<?php
   // Mention string here
   $string = "Tutorials Point!";
      
   // String before applying chop() function
   echo "String before chop() function: ". $string . " ";
   
   // String after applying chop() function
   echo chop($string, "Point!");
?>

Output

Here is the outcome of the following code −

String before chop() function: Tutorials Point!
Tutorials

Example 2

There is no character parameter mentioned in the following program. The newlines will be automatically deleted from the given string using the chop() function.

<?php
   // Mention your string here
   $string = "Hello TPians! \n best wishes \n \n"; 
   
   echo $string; 
   
   // Apply chop() function
   echo chop($string); 
   
   // After chop() function
   echo $string; 
?> 

Output

This will generate the below output −

Hello TPians! 
 best wishes 
 
Hello TPians! 
 best wishesHello TPians! 
 best wishes 

Example 3

In this example we will use the chop() method to delete or remove unnecessary slash (/) from the end of a file path so that the path is clean for further processing.

<?php
   // Mention filepath here
   $filePath = "/Users/My Docs/PHP/PhpProjects/filetext.txt/";
   
   // Use chop() function here
   $cleanPath = chop($filePath, "/");
   
   // Print the results
   echo "Original Path: $filePath\n";
   echo "Clean Path: $cleanPath\n";
?> 

Output

This will create the below output −

Original Path: /Users/My Docs/PHP/PhpProjects/filetext.txt/
Clean Path: /Users/My Docs/PHP/PhpProjects/filetext.txt

Example 4

Here we will clean up user input by removing a specific character (#) from the end of a string with the help of chop() function. This character is commonly used in formatting or as placeholder text.

<?php
   // Mention your string with special character here
   $userInput = "Welcome to PHP Tutorial!####";
   
   // Use chop() function here
   $cleanInput = chop($userInput, "#");
   
   // Print the results
   echo "Original Input: '$userInput'\n";
   echo "Cleaned Input: '$cleanInput'\n";
?> 

Output

Following is the output of the above code −

Original Input: 'Welcome to PHP Tutorial!####'
Cleaned Input: 'Welcome to PHP Tutorial!'
