You need to use preg_replace. Basically preg_replace() searches the subject for pattern matches and replaces them with the replacement.

<?php
 $string = 'Hello world, command data test com';
 $string = preg_replace('/bcomb/', '', $string);
 echo $string;
?>

Explanation: Above example pattern is explained below

b: Match a word boundary.
com: Text to match.

Short version:

join(' ',array_diff(explode(' ', $string), ['com']));

Explanation:

• 
  explode(' ', $string) splits your string into an array of words


• 
  array_diff($words, ['com']) removes the elements on the second array from the first array. So in case the array of $words contains the word com, it will be removed


• 
  join(' ', $words) concats all the strings in the $words array, dividing each word from each other with a space.

Full snippet:

<?php
$string = 'Hello world, command data test com';
$words = explode(' ', $string);
$words = array_diff($words, ['com']);
$string = join(' ', $words);
