php str_replace() function Video explanation

php str_replace() function syntax

Function:String replacement operation, case sensitive

Syntax: str_replace(find,replace,string,count)

Parameters:

Parameters	Description
find	Required. Specifies the value to look for.
replace	Required. Specifies the value to replace the value in find .
string	Required. Specifies the string to be searched for.
count	Optional. Variable counting the number of substitutions.

Description: Replace some characters in the string with other characters (case sensitive). If the searched string is an array, then it will return an array. If the string being searched is an array, then it will find and replace every element in the array. If both an array search and a replace are required, and the number of elements to be replaced is less than the number of elements found, the excess elements will be replaced with an empty string. If you are looking for an array and replacing a string, then the replacement string will work for all found values.
