Str_replace() in PHP

Post by natttt

The str_replace() function replace all occurrences of the search string with the replacement string

mixed str_replace ( mixed $search , mixed $replace , mixed $subject <, int &$count > )

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


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

output: Hello Peter!

$arr = array("blue","red","green","yellow");
echo "Replacements: $i";

output: Array
<0> => blue
<1> => pink
<2> => green
<3> => yellow
Replacements: 1
