remove a character from a string at a specific index in php

To remove a character from a specific index in a PHP string, you can use the substr_replace() function. This function replaces a portion of a string with another string. By passing an empty string as the replacement, you can effectively remove the character.

Here is an example code snippet that removes the character at index 3 from a string:

main.php
$string = "Hello World";
$string = substr_replace($string, "", 3, 1);
echo $string;
84 chars
4 lines

In the above code, the substr_replace() function takes four arguments:

1. The original string to modify.
2. An empty string as the replacement.
3. The index of the character to remove.
4. The number of characters to remove (in this case, 1).

The output of the code will be:

main.php
Helo World
11 chars
2 lines
