[SOLVED] Exact match

[redfox180]

Hi, do you know how to get a 'true' result just when there is an exact match on the word searched?

EX. substr('cash' 'ca') will result to 0 and not to false.

Thanks

James

I meant strpos...

[resago]

you could use preg_match with /b

 

[redfox180]

No, I mean in one entry when searching... Is there anything that I can put in front of $needle to say I just want an exact match??

[rhodesa]

are you looking for something like strcmp() ?

[redfox180]

not really...it doesnt solve the problm

humour me, my crystal ball's broken. Give some very specific examples of things you want to match and things you don't want to match, and provide some context to what you're trying to do.

let's say:

given

x=abcdef

y=cd

 

x=y false

x!=y true

 

if i set up a regular strpos, y being part of x will result to value 2. What i want is an absolute x and/or y, all in one statement. Any chance?

let's say:

given

x=abcdef

y=cd

 

x=y false

x!=y true

The built in operators work fine for what you're describing thus far.

$x = 'abcdef';
$y = 'cd';
if($x === $y){
  echo 'true';
}else{
  echo 'false';
}

 

 

What i want is an absolute x and/or y, all in one statement. Any chance?

Say what?

[redfox180]

say:

 

$fpym_res= 'CARL PAID BY CASH'

$fop_cash=strpos($fpym_res, "CASH");
    if ($fop_cash===FALSE)
        $pay_cash="";
    else
        $pay_cash="CASH";

$fop_ca=strpos($fpym_res, CA);
    if ($fop_ca===FALSE)
        $pay_ca="";
    else
        $pay_ca="CA";
$pay="$pay_cash$pay_ca;

The result will be CACASH and not CASH. That's why I said if you know how to 'limit' the request to an exact match when searching for a word...

In this case, you're better off explod()'ing the string into an array, trim()'ing each element, and then checking if the values you want to find exist. 

 

<?php
$fpym_res= 'CARL PAID BY CASH';
$arr = explode(' ', $fpym_res);
$arr = array_map('trim', $arr);
if(in_array('CASH', $arr)){
  echo 'cash';
}else if(in_array('CA', $arr)){
  echo 'ca';
}
?>

[redfox180]

That's better! It makes more sense too... I'll need to review Arrays in PHP

Cheers
