Remove part in PHP

In PHP, you can remove part of a string using the substr_replace() or str_replace() functions.

substr_replace() function:
The substr_replace() function replaces a part of a string with another string. The syntax is as follows:

substr_replace($original_string, $replacement_string, $start, $length)

Here is an example:

$original_string = "Hello World";
$replacement_string = "Friend";
$start = 6;
$length = 5;
$new_string = substr_replace($original_string, $replacement_string, $start, $length);
echo $new_string; // Outputs: Hello Friend

In this example, we are replacing the substring "World" with "Friend" starting from the 6th character of the original string. The output is "Hello Friend".

str_replace() function:
The str_replace() function replaces all occurrences of a string with another string. The syntax is as follows:

str_replace($search, $replace, $original_string)

Here is an example:

$original_string = "Hello World";
$search = "World";
$replace = "";
$new_string = str_replace($search, $replace, $original_string);
echo $new_string; //Outputs: Hello

In this example, we are removing the substring "World" from the original string using the str_replace() function. The output is "Hello".
