PHP Interview Programs

Interview Practice Index

PHP interview programs are small coding tasks used to check syntax fluency, control flow, arrays, and problem-solving. This hub lists every exercise on CodeToFun with the same mobile-friendly tutorial shell used across the site—overview, algorithm, code, FAQs, and complexity notes.

Interview Programs in PHP

Topics you will commonly touch while working through the cards below include:

  • Core syntax: variables, operators, if/else, for/foreach/while, and functions.
  • Arrays and strings: traversal, counting, splitting/joining, and simple transformations.
  • References when needed: passing by reference (&$var) for swap-style problems.
  • Recursion: where a problem naturally repeats with a smaller input.
  • Searching and sorting ideas: linear scans, comparisons, and classic patterns from coursework.
  • File and streams (later tracks): reading lines with fopen/fgets or equivalent helpers.
  • Light math: primes, factors, digit tricks, bases, and matrices—the bulk of this index.
  • Problem-solving: stating assumptions, handling invalid input, and explaining complexity aloud.

Solving these builds confidence for whiteboard-style prompts and timed IDE rounds alike.

Did you know?

Tip: Practice in order of comfort—basic number checks first, then array loops, conversions, and matrix walks. Each program uses the same tutorial layout so you always know where to find pseudocode, edge cases, and complexity notes.
