scripting - PHP strstr difference issue -

-

so have problem. have snippet of code see if phrase present in phrase:

if(strstr($matches[1], $query))

so example if:

$matches[1] = "arctic white" $query = "arctic"

in case above, code detect phrase "arctic" in phrase "arctic white" although, want detect if inside words , not phrases.

for example if:

$matches[1] = "antarctica" $query = "arctic"

in case script not detect word "arctic" in "antarctica" although is. wondering, how can edit if(strstr($matches[1], $query)) detect words have $query content in it? please help!

you can use preg_match() better result. preg_match doesn't encompass regular expressions only. can need. i.e.:

if (preg_match("/arctic/i", "antarctica")) {     // there } else {     // not there else }

btw, small "i" means case sensitivity, check php manual more examples: http://php.net/manual/en/function.preg-match.php
