[SOLVED] If begins with..

[wwfc_barmy_army]

Hello.

 

I need an if-else statement where is looks to see if the field starts with a certain word, how would i go about this?

 

Thanks.

$string = substr($text, 0, 5);

if ($string == "start") {echo "contains the start string!"}

else {echo "doesnt contain the start string!"}

 

I think this is what you want, btw, change 5 to the number of strings of the start word, like "start" has 5 characters.

<?php

if(strpos($string, $start) === 0)
echo "Starts!";
else
echo "Doesn't!";

?>

oh, strpos can change to see the ideal position? never know that.

(do orio's)

Well, strpos() "Returns the numeric position of the first occurrence of needle in the haystack string" (from the manual). It returns FALSE if it wasn't found, and that's why you need to use the === operator (because 0==FALSE is true, and 0===FALSE is false).

Can you just confirm where the field would go in there, and where the text i am looking for would go in there? is it;

 

$string - where it gets the field

 

$start - the text i want to search for in the field

 

And what does the '=== 0' do?

 

Thanks.

thanks orio, wwfc_barmy_army, thats right.

$string- The string coming from that field of yours.

$start- The string you are using to check if it's the start of $string

The " === 0" part- Checks if $start was found in the beginning of $string (using the strpos() function).

1 last question, how would i be able to say if it starts with this or this?

 

What i have so far is:

<?php
if(strpos($qry[link], "http://") === 0)
echo "Starts!";
else
echo "Doesn't!";
?>

 

But if i try putting the or operator (||) after it always says 'doesnt'.

 

Thanks

<?php
if(strpos($qry[link], "http://") === 0 || strpos($qry[link], "ftp://") === 0)
echo "Starts!";
else
echo "Doesn't!";
?>
