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. The str_replace() is a built-in function in PHP and is used to replace all the occurrences of the search string or array of search strings by a replacement string or array of replacement strings in the given string or array respectively. We can replace the string with another by using PHP str_replace(). This method is case-sensitive, so the programmer has to take care of the case while programming and interpreting the output.
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$string="Geeks for Geeks";//replace zambiatek in the string with computerecho str_replace("Geeks","computer",$string);?> |
Output:
computer for computer
Example 2: The following code replaces the string with empty.
PHP
<?php//input string$string="Geeks for Geeks";//replace zambiatek in the string with emptyecho str_replace("Geeks","",$string);?> |
Output:
for
Example 3: The following code replaces the string with integers.
PHP
<?php//input string$string="Geeks for Geeks";//replace zambiatek in the string with value - 1echo str_replace("Geeks",1,$string);?> |
Output:
1 for 1
