Breaking down strings in php

A string contains (n) amount of words letters or symbols.The string contains data inserted by the user. Can I break down the string and search for a specific word, phrase or symbol in the string and echo something if the the user has typed what I was searching for. If there is a way please explain. Thanks 😀

try this: $string = "this is a sample string"; $arr = explode(' ' , $string); foreach ( $arr as $elem ){ if ( $elem == "sample" ) { echo "ok, is just a sample"; } }

Make sure that your delimiter is a space and not an empty string.

@Claudio Vidal I copied the exact code above but it does not seem to work. errors: explode() : empty delimiter invalid argument supplied for forearch()
