如何在PHP中拆分数组？ [关闭]

I'm new to PHP, please help me to split this array. I never do this before.

I only want to show value http://domainXXX.com without string(18) on browser.

array(3) {
    [7] => string(18)
    "http://domain7.com" 
    [4] => string(18)
    "http://domain4.com" 
    [3] => string(18)
    "http://domain3.com"
}

Assuming the array looks like this, a simple foreach loop should allow you to output the urls

$links=array(
    7   =>  'http://domain7.com',
    4   =>  'http://domain4.com',
    3   =>  'http://domain3.com'
);
foreach( $links as $key => $url ) {
    echo $key,' ',$url,'<br />';
}

don't use direct var_dump() to display output; you can use foreach() or any loop and foreach() has following-

//lets say your array name is $array
// here $key will hold 7,4,3 and $values will hold your domains
foreach($array as $key=>$value)
{
     echo $value.'<br>';
}
