Difference between str_replace and substr_replace
str_replace —
Replace all occurrences of the search string with the
replacement string.
Example for str_replace()
<?php
echo str_replace("world","siva","Hello world!");
?>
substr_replace -
The function substr_replace introduces some additional
functionality to compliment str_replace. substr_replace is a
more mathematically based replace function, which relies on
starting points and lengths to replace parts of strings, as
opposed to searching and replacing.
Example for substr_replace()
//string that needs to be customized
$original = "ABC123 Hello Mr. siva! DEF321";
//starting point 5
$sp5 = substr_replace($original, "Five", 5);
//starting point 12
$sp12 = substr_replace($original, "Twelve", 12);
//starting point 0
$sp0 = substr_replace($original, "Zero", 0);
//starting point -1
$spneg1 = substr_replace($original, "Negative 1", -1);
//Echo each string
echo "Original String: $original <br />";
echo "Starting Point 5: $sp5 <br />";
echo "Starting Point 12: $sp12 <br />";
echo "Starting Point 0: $sp0 <br />";
echo "Starting Point -1: $spneg1 ";
