How to replace String in PHP ?
In this article, we are going to replace the String with another by using the PHP built-in str_replace() function.
A String is a collection of characters.
We can replace the string with other by using PHP str_replace().
Syntax:
str_replace(substring,new_replaced_string,original_string);
We need to provide three parameters.
- substring is the string present in the original string that should be replaced
- replaced_string is the new string that replaces the substring.
- original_string is the input string.
Example 1: The following code replaces the string with another string.
PHP
<?php //input string $string = "Geeks for Geeks" ; //replace geeks in the string with computer echo str_replace ( "Geeks" , "computer" , $string ); ?> |
Output:
computer for computer
Example 2: The following code replaces the string with empty.
PHP
<?php //input string $string = "Geeks for Geeks" ; //replace geeks in the string with empty echo str_replace ( "Geeks" , "" , $string ); ?> |
Output:
for
Example 3: The following code replaces the string with integers.
PHP
<?php //input string $string = "Geeks for Geeks" ; //replace geeks in the string with value - 1 echo str_replace ( "Geeks" ,1, $string ); ?> |
Output:
1 for 1
