Replace a part of the string in PHP

In this blog we will see how we can replace a part of the string, sometimes we have to change some string parts let’s suppose you have string name as free_shipping_title and you want to make it as free_shipping_status.

So we will how we can do this stuff in PHP in a very easy manner. To replace a part of the string we will use the PHP str_replace function.

Defination and usage

The str_replace() function replaces some characters with some other characters in a string.

This function works by the following rules:

  • If the string to be searched is an array, it returns an array
  • If the string to be searched is an array, find and replace is performed with every array element
  • If both find and replace are arrays, and replace has fewer elements than find, an empty string will be used as replace
  • If find is an array and replace is a string, the replace string will be used for every find value

Note: This function is case-sensitive. Use the str_ireplace() function to perform a case-insensitive search.

Note: This function is binary-safe.


echo str_replace("title","status","free_shipping_title");
