str_replace() Function in PHP
Previous Home Next


The str_replace() function replaces some characters with some other characters in a string. This function works by the following rules:

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


echo str_replace("world","India!","Hello world"); 


Hello India!

In the above example you search the string Hello world and world string replaces by India. Thus the result output is Hello India!
