Strengthen your PHP problem-solving skills by learning to select, implement, and analyze common algorithms and data structures. Explore sorting, searching, linked lists, stacks, queues, arrays, dictionaries, sets, and hashing.
What you'll learn
Analyze the time and space complexity of algorithms and data structures
Implement sorting and searching algorithms in PHP
Build and manipulate linked lists for algorithmic problems
Apply stacks and queues to appropriate problem-solving scenarios
Use indexed arrays, dictionaries, sets, hash maps, and hash sets in PHP
Select suitable algorithms and data structures based on problem requirements
Solve interview-style coding challenges using structured reasoning
Advantages and disadvantages
Advantages
University courses you can audit for free, with lectures, readings and practice quizzes.
A verified certificate from the university if you pay for it.
Self-paced: start any time.
Disadvantages
Graded assignments and the certificate need the paid track.
Audit access can expire a few weeks after the course ends.
Learning is free, but the certificate costs money.
Some parts (graded work, certificate) are paid.
Some points apply to every course of this kind; see how we rank.
Free to audit
Free: Choose "Audit this course" when you enrol: lectures, readings and practice are free.
Paid: Graded assignments and the verified certificate (Certificate $75). Audit access may end after the course closes.
