how can i compaire a string in LIKE analogy of MySQL

[snk]

hello again,

 

I want to make a name comparison of a string but I want to to not be stricted exactly on the string's name

for example:

if($a == "exactly"){...} if string is 1exactly2 then the statement will never be true. how can i make it true?

 

thanks

you can use strpos

 

 

 

[trq]

<?php

   $a = "this is exactly one string";
   if (preg_match('/exactly/',$a)) {
       echo "found";
   } else {
       echo "not found";

   }  

?>

RegEx. Stands for Regular Expressions. http://www.google.com/search?channel=s&hl=en&q=RegEx+PHP&btnG=Google+Search

Yeap regex is the answer, thanks m8

[snk]

<?php

    $a = "this is exactly one string";
    if (preg_match('/exactly/',$a)) {
        echo "found";
    } else {
        echo "not found";

    }  

?>

if exactly is value? how do i use it? i try if (preg_match('/$some_value/',$a)) and nothing happens.

thanks

should be

 

if (preg_match("/$some_value/",$a)) 

 

use double quotes instead of single quotes

[snk]

i have 

if (preg_match("/$search_criteria/",$word[i])){

 

but it doesnt work.. can you see anything wrong with the [] of the second value or something else?

 

thanks for your help, its my first time in regex and a have harsh times.

please echo your $search_criteria and $word before that and let me know what it is

 

 

echo $search_criteria;
echo $word;

if (preg_match("/$search_criteria/",$word)){

[snk]

sorry i edited the code, i have

 

if (preg_match("/$search_criteria/",$word[i])){

 

sorry again, i didnt know that takes away the brackets if i dont put it in code tag

[snk]

$search_criteria = $_POST('search_criteria'); //echoes whatever i put in my form correctly
  $str = file_get_contents("http://www.dcs.napier.ac.uk/~cs170/32037lnotes.html");
  $word = explode(" ",$str);

//echoes everything right

 

[rajivgonsalves]

what exactly are you trying to achieve by this code ?

[snk]

aaaaaxxxxx damn again i was forgoting to put $ in i at $word

 

you were absolute right... "/$search_criteria/" works..!

 

thank you.. and sorry for the troubles that i created with my stupid observation
