PHP格式分割數爲獨立的HTML標籤

Question

我怎麼會去和分離號碼12345弄成這個樣子用PHP：

<span>1</span> 
<span>2</span> 
<span>3</span> 
<span>4</span> 
<span>5</span> 

Answer 1

echo preg_replace('((.))', "<span>$1</span>\n", '12345'); 

Answer 2

嘗試用：

$input = 12345; 
foreach (str_split($input) as $char) { 
    echo '<span>' . $char . '</span>'; 
} 

Answer 3

var arr = explode('', "12345"); 

然後遍歷throgh它與foreach和回聲（或做任何你想要的）標籤。

Answer 4

隨着str_split()

<?php 
$str="12345"; 
$str = str_split($str); 

foreach ($str as $letter){ 
    echo '<span>'.$letter.'</span>'.PHP_EOL; 
} 
?> 

Answer 5

$str = '12345'; 
$arr = str_split($str); 

foreach ($arr as $char) { 
    echo '<span>' . $char . '</span>'; 
} 

Answer 6

如果輸入字符串會很大，這樣的事情將是更多的內存友好，並可能更快，因爲它流，而不是開的第一打破它。

$string = "12345"; 

for ($i = 0, $j = strlen($string); $i < $j; $i++) { 
    echo "<span>" . $string{$i} . "</span>\n"; 
}
