What Alternatives Are Available for the Deprecated PHP Split Function?

An Alternative to the Deprecated PHP split Function

The PHP split function has been marked as deprecated, indicating that it is no longer recommended for use in modern code. As an alternative, developers are advised to switch to a suitable replacement function.

explode: A Split Function Alternative

One of the alternative functions to split is explode. It takes a delimiter as the first argument and a string as the second argument, and returns an array of the substrings that were split. For example:

$string = "hello,world,beautiful,day";
$delimiter = ",";
$result = explode($delimiter, $string);

The $result variable will now contain an array with the following elements:

• 'hello'
• 'world'
• 'beautiful'
• 'day'

preg_split: A Regular Expression Split Function

If the original split function was utilized to divide strings using regular expressions, developers can employ the preg_split function as a replacement. This function takes a regular expression as the first argument and a string as the second argument, and returns an array of substrings that were divided by the regular expression. For instance:

$string = "hello_world_beautiful_day";
$regex = "/\_/";
$result = preg_split($regex, $string);

The $result variable will now hold an array with these parts:

• 'hello'
• 'world'
• 'beautiful'
• 'day'
