PHP str_replace() Function

Hello folks! welcome back to a new edition of our tutorial on PHP. In this tutorial guide, we are going to be studying about the PHP str_replace() Function.

The PHP str_replace() function is used to replace the string with another string.

This function follows some specified rules while working, these rules are given below:

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

This built-in function is the case-sensitive version of str_ireplace() function.


Following below is the syntax to use this function -
