Common Mistakes

Using a semicolon instead of a comma in the pattern.

Not enclosing the pattern in slashes.

The pattern /,/ matches commas, so preg_split splits the string at commas.

💡 Hint

Common Mistakes

Using a comma instead of whitespace in the pattern.

Not using the plus sign to match multiple spaces.

The pattern /\s+/ matches one or more whitespace characters, so preg_split splits the string at spaces.

hard

Fix the error in the code to split the string by dots using preg_split.

💡 Hint

Common Mistakes

Not escaping the dot, which matches any character.

Using incorrect escaping that causes syntax errors.

The dot . is a special character in regex, so it must be escaped as \. to match a literal dot.

Complete the code to split the string by commas or semicolons using preg_split.

PHP

<?php
$string = "red,green;blue,yellow;orange";
$colors = preg_split([1], $string);

💡 Hint

Common Mistakes

Using separate patterns for commas and semicolons.

Not using square brackets to combine characters.

The pattern /[,;]/ matches either a comma or a semicolon, so preg_split splits the string at both.

💡 Hint

Common Mistakes

Using separate patterns for each delimiter.

Not including the plus sign to match multiple delimiters in a row.

The pattern /[ ,;]+/ matches one or more spaces, commas, or semicolons, splitting the string at any of these characters.
