[SOLVED] Checking if 2 words are in a text

[Nexy]

Why Hello There!  How would I be able to something like this:

 

if($text contains a specific word == "word1" && $text contains another specific word == "word2")

{

        do something;

}

 

Basically, if word1 and word2 are in the variable $text in respective order, then do something. Also, $text can contain any other words in there too. So if there was something like this:

 

$text = "Hello word1 there! Welcome to word2 today!";

 

Then the if statement would see those 2 words are in there in order. But if it's something like this:

 

$text = "Hello word2 there! Welcome to word1 today!";

 

Then do nothing, since "word1" is not first. I hope that made sense. Any help would be appreciated.

 

Thank You!

try this

if(!strstr(strstr($text,"word1"),"word2")===false){

strstr will return the part of the string after it finds the first occurrence so you search for word1 in

Hello word1 there! Welcome to word2 today

you get

 there! Welcome to word2 today

so then you search again for word to and if it cant find it it will return FALSE

my solution:

<?php
$text = "this is a test";
$word1 = "this";
$word2 = "test";
if ((strstr($text, $word1) && strstr($text, $word2)) && strpos($text, $word1) < strpos($text, $word2)){
print "it's true!";
}
?>

Thank You, both of you!! Both methods worked perfectly.  :) :)

but wouldn't that take longer because it does two strstr like mine and also does two strpos checks

you are correct. I was just giving him another option, because I had already written it while you were posting. Hate to waste code.

or you may also try:

 

<?php
if(strpos(strstr($mystring, $word1), $word2) !== false) {
	echo "Match found";
}
?>

 

the reason i replaced the strstr() in the last one with strpos() is because we only aim to get the occurence other than the string itself since strpos() is faster and less memory intensive function.

 

if you want to totally remove strstr(), you may use strpos() then just apply the third parameter offset which is the result of the first strpos() + strlen() of the first string... which i think may only become more costly, though I haven't used this one and untested.

oh, somebody made a post already... ahahah
