In fact im working in a small php script , I'm using simple html dom to get some tags for a website, any way this is the code that i'm using
if( strpos($a, '#') !== false )
{
if( strpos($a, 'page') !== false ){}
else
{
if( strpos($a, '#') !== false ){}
else{
$items[] = $a;
}
}
}
I want to delete duplicate string in the array $items.
Why not just check to see if the string has already been added?
if( strpos($a, '#') !== false )
{
if( strpos($a, 'page') !== false ){}
else
{
if( strpos($a, '#') !== false ){}
else{
if(!in_array($a, $items)){
$items[] = $a;
}
}
}
}
This is from a comment of php.net (https://www.php.net/function.array-unique)
<?php
$input = array("a" => "green", "red", "b" => "green", "blue", "red");
$result = array_unique($input);
print_r($result);
?>
Output: Array ( [a] => green [0] => red [1] => blue )
Thanks Mark!
If you can't check for already added items for some reason (as previously suggested) you could take a look at the array_unique() method.
/edit:
This is unrelated to the question, but just in case that the snippet you posted is your actual code: you should really not use if( strpos($a, 'page') !== false ){} else ...
Just invert the condition and place the code in the if block:
if (strpos($a, 'page') === false) {
// your code here
}
