PHP - 爆炸中的每一項創建由爆炸

Question

我的代碼是一個數組...

$string ="foo:bar,bar,bar|foo2:bar2,bar2,bar2"; 

$first_array = explode("|", $string); 

function split(&$block) { 

$block = explode(":", $block); 

} 

array_walk($first_array, "split"); 

echo $block["0"]["0"]; 
echo "<br />"; 
echo $block["0"]["1"]; 

?> 

感謝您的幫助迄今。從我所收集的這應該是提供的代碼的乾淨版本。這不會迴應任何內容，也不會提供代碼。

Answer 1

這將這樣的伎倆：

$string ="foo:bar:bar:bar|foo2:bar2:bar2:bar2"; 

// first explode on | 
$first_array = explode("|", $string); 
// this function go on each lines of an array and transform each by a function 
array_walk($first_array, function(&$item) { 
     // so for each line explode with ':' as delimiter 
     $item = explode(':', $item); 
}); 

// To check all lines of the array 
foreach($first_array as $line_array) { 
    //my code for each sub-array 
} 

// To get only the last (second) 
$second_sub = array_pop($first_array); 

// if you want one dimension with all exploded you can use 
// this function split with a regexp pattern 
// "/[\|:,]+/" foreach "|" or ":" or "," split the string 
preg_split("/[\|:,]+/", $string);

不要使用$塊，因爲它在另一個示波器的定義，而且你不能給「拆分」爲你的函數的名稱，因爲它是一個現有的PHP函數

$string ="foo:bar,bar,bar|foo2:bar2,bar2,bar2"; 

$first_array = explode("|", $string); 

function mysplit(&$block) { 

$block = explode(":", $block); 

} 

array_walk($first_array, "mysplit"); 

echo $first_array[0][0]; 
echo "<br />"; 
echo $first_array[0][1];
