Php foreach loop without to override variables - php

Question

I have difficult times to figure out how to manage my loop to not override variables during the process, my example script looks as it follows
$targets = array(
array(
'site_id' => 1,
'url' => array('http://example.com','http://test.com'),
'title' => "Title_1",
'int_link' => "/internal_link/",
'icon' => '/icon_2.gif',
'teaser_index' => 5),
array(
'site_id' => 2,
'url' => array('http://example2.com','http://test2.com'),
'title' => "Title_2",
'int_link' => "/internal_link/",
'icon' => '/icon_2.gif',
'teaser_index' => 5)
)
foreach($targets as $target){
$images = array();
$links = array();
$name = array();
$loop=-1;
foreach($target['url'] as $url){
$loop++;
//parsing $url;
//the insider loop has 2 iterations
if ($loop=1){
$content .="<div>".$target['title'].$url"</div>";
}
else{
$content .="<div>".$target['title'].$url"</div>";
}
}
//write $content html to database, without to override the first $content
}

Your question is not clear but i think i understand what the likely problem might be
There are so many errors in the script which you need to fix maybe your script would run the way you want it to be .
A. $content was not define .. you need to define it
B. if ($loop=1){ should be if ($loop == 1){
C. $content .="<div>".$target['title'].$url"</div>"; is missing . and it should be something like this $content .= "<div>" . $target['title'] . $url . "</div>";
D. You if condition does not make sense since you are outputting the same information
Form what i can see you want to output Title & URL you can as well just use this simple script (Just Guessing)
$targets = array(
array(
'site_id' => 1,
'url' => array('http://example.com','http://test.com'),
'title' => "Title_1",
'int_link' => "/internal_link/",
'icon' => '/icon_2.gif',
'teaser_index' => 5),
array(
'site_id' => 2,
'url' => array('http://example2.com','http://test2.com'),
'title' => "Title_2",
'int_link' => "/internal_link/",
'icon' => '/icon_2.gif',
'teaser_index' => 5)
);
foreach ( $targets as $target ) {
$content = "";
$output = "<div> %s : %s </div>";
$content .= sprintf($output, $target['title'], implode(" , ",$target['url']));
echo $content;
// write $content html to database, without to override the first $content
}
Output
Title_1 : http://example.com , http://test.com
Title_2 : http://example2.com , http://test2.com
