[SOLVED] strstr

[glenelkins]

Hi

 

Just wondering if anyone can see why this if statement doesnt execute the die() function:

 

$var1 = 'something.something.co.uk';
$var2 = '.co.uk';

if ( strstr ( $var1, $var2 ) ) {

    die ( 'OK' );

}

[glenelkins]

this is stange! if the $var2 is pulled from the database strstr doesnt work...if i set it manually it does work..wtf!

From the manual:

 

Returns part of haystack string from the first occurrence of needle  to the end of haystack.

 

Thus strstr returns an empty string as there isn't anything left after .co.uk therefor use type comparison:

 

if (false !== strstr($var1, $var2)) {

this is stange! if the $var2 is pulled from the database strstr doesnt work...if i set it manually it does work..wtf!

 

Can you post this script, thank you.

i will post some example code. It makes no sense to why the strstr is not picking up the .co.uk from the first array element. The * is removed so the needle becomes .co.uk

 

$array = array ( '*.co.uk', '*.com' );

// THE ARRAY IS GENERATED FROM DATABASE SERIALIZED DATABASE VALUES. using unserialize() to create the array
// if i create the array manually then it works ok

$hostname = gethostbyaddr ( '111.111.111.111' ); // for example. server.domain.co.uk

foreach ( $array as $item ) {

    // remove the *
    // will leave .co.uk  on the first element
    $item = ltrim ( $item, '*' );

    if ( strstr ( $hostname, $item ) ) {

        die ( 'OK' );

    }

}

here ill add a bit more for the example. lets build the array from an imaginery database table

 

$result = mysql_query ( "SELECT `data` FROM `test`" );
list ( $data ) = mysql_fetch_array ( $result );

$array = unserialize ( $data );

// array ( '*.co.uk' )

 

The strstr doesnt work with this however it will work if i do:

 

$array = array ( '*.co.uk' );

 

WTF WTF WTF

 

[glenelkins]

the problem seems to occur when the array has more than 1 item

solved..it was a bloody \n causing the issue
