MySQL PHP search: four-part video tutorial series
Fresh from Adam Khoury's massive library of instructional videos comes a four-part, full-fledged tutorial on searching a MySQL database using PHP.
The tutorials use the 'worked example' format (like Khan Academy), which makes learning relatively painless for newbies and not completely useless for more experienced developers.
Adam lists the specifics in his YouTube video description:
MySQL PHP Search Programming Exercises for database driven web sites. Search pages that allow advanced targeting and filtering of information. Learn to build HTML Search Forms and Advanced Search Filters, Various MySQL Search Query Methods, Joined Table Queries Targeting Multiple Tables, Natural Language Full-Text Search Queries, Boolean Full-Text Search Queries and discuss fine tuning your search programming and adjusting search parameters.
