Hi Guys,

In this blog,I will explain you how remove white space from string You can use the PHP trim() function to remove whitespace including non-breaking spaces newlines, and tabs from the beginning and end of the string. It will not remove whitespace occurs in the middle of the string. Let's take a visual examination of an example to understand how it rudimentally works:

Method : 1

Syntax:

trim(string,charlist);

Example

<?php

    $my_str = '    Welcome to MyWebtuts.com ';
    echo strlen($my_str); // Outputs: 29
    echo $my_str."
";
     
    $trimmed_str = trim($my_str);
    echo strlen($trimmed_str); // Outputs: 24
    echo $trimmed_str."
";

?>

Output

29    Welcome to MyWebtuts.com 
24Welcome to MyWebtuts.com

Method : 2

Now,Let's see another function to remove white space from string Utilizing str_replace() Method: The str_replace() method is utilized to supersede all the occurrences of the search string (” “) by replacing string (“”) in the given string str.

Syntax:

str_replace(find,replace,string,count)

Example

<?php

    // PHP program to remove all whitespaces from a string 
      
    // Declare a string
    $str = "  Welcome to   MyWebtuts.com  "; 
        
    // Using str_replace() function 
    // to removes all whitespaces  
    $str = str_replace(' ', '', $str);
      
    // Printing the result
    echo $str;

?>

Output

WelcometoMyWebtuts.com

The difference between str_replace and str_ireplace is that str_ireplace is a case-insensitive.

Syntax:

str_ireplace(find,replace,string,count)

Example

<?php

    // PHP program to remove all whitespaces from a string 
      
    // Declare a string
    $str = "  Welcome to   MyWebtuts.com  "; 
        
    // Using str_ireplace() function 
    // to removes all whitespaces  
    $str = str_ireplace(' ', '', $str);
      
    // Printing the result
    echo $str;

?>

Output

WelcometoMyWebtuts.com

Method : 3

Using preg_replace() Method: The preg_replace() method is utilized to perform a regular expression for search and replace the content.

Syntax:

preg_replace(patterns, replacements, input, limit, count)

Example

<?php

    // PHP program to remove all whitespaces from a string 
      
    $str = "  Welcome to   MyWebtuts.com  "; 
        
    // Using preg_replace() function 
    // to remove all whitespaces  
    $str = preg_replace('/\s+/', '', $str);
      
    // Printing the result
    echo $str; 

?>

Output
