在Aaray中查找，然後替換或添加它的值with.png

Question

這裏是一些命令。

$filewithoutext = array("1F621", "1F536", "1F365", "1F33B", "1F193", "0035-20E3"); 
$changtofilename = str_replace($vowels, ".png", "1F536 1F621"); 

我的要求是，如果值找到（1F33B 1F193）則系統將其更改爲.png格式像1F536.png 1F621.png

Answer 1

$find = array('1F33B', '1F621'); 
    $replace = array('1F33B.png', '1F621.png'); 
    $filewithoutext = array("1F621", "1F536", "1F365", "1F33B", "1F193", "0035-20E3"); 
    $changtofilename = str_replace($find, $replace, $filewithoutext); 

Answer 2

試試這個，

<?php 
    $vowels = array("1C536", "1F621"); 
    $array = array("1F621", "1F536", "1F365", "1F33B", "1F193", "0035-20E3"); 
    foreach ($vowels as $key => $val) { 
     if (in_array($val, $array)) { 
      $key = array_search($val, $array); 
      $array[$key] = $array[$key] . ".png"; 
     } 
    } 
    print_r($array);

Answer 3

使用array_map和anonymous function

$files = array("1F621", "1F536", "1F365", "1F33B", "1F193", "0035-20E3"); 
$targets = array("1F536", "1F621"); 

$filesWithExtensions = array_map(function($item) use ($targets) { 
    if (in_array($item, $targets)) { 
     $item .= '.png'; 
    } 
    return $item; 
}, $files); 

print_r($filesWithExtensions); 

Answer 4

嘗試以下解決方案：

<?php 
$vowels = array("1F536", "1F621"); 
$array = array("1F621", "1F536", "1F365", "1F33B", "1F193", "0035-20E3"); 

$arr = array_map(function(&$val) use($vowels){ 
    $value = (in_array($val, $vowels) !== false) ? $val . '.png' : $val; 
    return $value; 
}, $array); 

print_r($arr); 

$arr將有希望的結果。
