如何从foreach PHP获得第一个非空过滤值？

Question

I have an array then i filtered the value and the result is null/empty.

How to determine first filtered value that non empty?

<?php

$items = array('a1a','bb2','o3e','two','three');

$i=0;

foreach($items as $item) {

    $item = str_replace('a1a','',$item); //filter remove
    $item = str_replace('bb2','',$item); //filter remove
    $item = str_replace('o3e','',$item); //filter remove

    //ITRY THIS BUT NOT WORK IF THE SECOND AND THIRD IS EMPTY/NULL TOO
    if($i==0) {
        if(empty($item)){
            //skip
        } else {
            //STATUS PUBLISH
        }

    } else { 
        //STATUS ATTACHMENT
    }

$i++;           
}

How to get first non empty filtered value from foreach PHP?

If I understood correctly, you want the first item from they array $items that has not been emptied with your str_replace.

If this is correct, here is how to proceed:

<?php
$items = array('a1a','bb2','o3e','two','three');

$first = true;
foreach($items as $item) {
    $itemOriginal = $item;
    $item = str_replace(['a1a', 'bb2', 'o3e'] ,'',$item); //filter remove

    if(!empty($item) && $first == true){
        $first = false;
        echo "status publish -> ".$itemOriginal."
";
    } else {
        echo "skip -> ".$itemOriginal."
";
    }
}

This will output:

skip -> a1a
skip -> bb2
skip -> o3e
status publish -> two
skip -> three

If this is not what you want, please clarify your question and add a comment so I can look at it again.

Update:

can value 'three' not skip? so i want to make wordpress publish using php from value foreach. the first value 'two' as publish and 'three' the next is as attachment

<?php
$items = array('a1a','bb2','o3e','two','three');

$first = true;
foreach($items as $item) {
    $itemOriginal = $item;
    $item = str_replace(['a1a', 'bb2', 'o3e'] ,'',$item); //filter remove

    if(!empty($item) && $first == true){
        $first = false;
        echo "status publish -> ".$itemOriginal."
";
    } elseif(!empty($item)) {
        $first = false;
        echo "status attachment -> ".$itemOriginal."
";
    } else {
        echo "skip -> ".$itemOriginal."
";
    }
}

will output:

skip -> a1a
skip -> bb2
skip -> o3e
status publish -> two
status attachment -> three
