How to split string by space in PHP?

@lew 

To split a string by space in PHP, you can use the explode() function. This function takes two arguments: the string to split and the delimiter to split it by. For example:

1
2
3
4

$string = "This is a string";

// Split the string by space
$parts = explode(" ", $string);

This will split the string into an array of parts, with each element containing one word from the original string. You can then access each part of the string using the array indexes, like this:

1
2
3
4

echo $parts[0]; // Outputs: "This"
echo $parts[1]; // Outputs: "is"
echo $parts[2]; // Outputs: "a"
echo $parts[3]; // Outputs: "string"

Alternatively, you can use the preg_split() function to split a string by space in PHP. This function takes a regular expression as the delimiter, so you can use the s pattern to match any whitespace characters, including spaces, tabs, and newlines. For example:

1
2
3
4

$string = "This is a string";

// Split the string by space
$parts = preg_split("/s/", $string);

This will give you the same result as using explode(), but using a regular expression as the delimiter allows for more flexibility and control over the split. For example, you could use the s+ pattern to match one or more consecutive whitespace characters, which would allow you to split a string by multiple spaces or other whitespace characters.
