php - 如何从字符串中获取关联数组

Question

我有一个字符串，例如：-

$attributes = "id=1 username=puneet mobile=0987778987 u_id=232";

现在，我想以以下关联数组格式获取它：-

$attributes{'id' => 1, 'username' => puneet, 'mobile' => 0987778987, 'u_id' => 232}

注意：- 这些所有值仅由空格分隔。任何帮助都将是可观的。

Answer 1

$final_array = array();

$kvps = explode(' ', $attributes);
foreach( $kvps as $kvp ) {
    list($k, $v) = explode('=', $kvp);
    $final_array[$k] = $v;
}

Answer 2

$temp1 = explode(" ", $attributes);
foreach($temp1 as $v){
 $temp2 = explode("=", $v);
 $attributes[$temp2[0]] = $temp2[1];
}

爆炸

Answer 3

我可以建议你用正则表达式来做：

$str = "id=1 username=puneet mobile=0987778987 u_id=232";
$matches = array();
preg_match_all( '/(?P<key>\w+)\=(?P<val>[^\s]+)/', $str, $matches );
$res = array_combine( $matches['key'], $matches['val'] );

此代码将解决您的问题。

<?php
$attributes = "id=1 username=puneet mobile=0987778987 u_id=232";
$a = explode ( ' ', $attributes) ;
$new_array = array();
foreach($a as $value)
{
    //echo $value;
    $pos = strrpos($value, "=");
    $key = substr($value, 0, $pos);
    $value = substr($value, $pos+1);

    $new_array[$key] = $value;
}
print_r($new_array);
?>

这段代码的输出是

Array ( [id] => 1 [username] => puneet [mobile] => 0987778987 [u_id] => 232 )

Answer 5

我认为您必须将此字符串拆分两次

1. 用空间划分
2. 与'='
