将数组数组值存储在一个逗号分隔的字符串中

问题描述：

I have this return array

 $leaseArray =  Array ( [0] => Array ( [LeaseNumber] => OL/2011/0343 ) [1] => Array ( [LeaseNumber] => 184 ) [2] => Array ( [LeaseNumber] => OL/2011/0118 ) [3] => Array ( [LeaseNumber] => OL/2016/1759 ) [4] => Array ( [LeaseNumber] => OL/2013/0858 ) [5] => Array ( [LeaseNumber] => OL/2012/0535 ) [6] => Array ( [LeaseNumber] => OL/2017/2208 ) [7] => Array ( [LeaseNumber] => 2355 ) )

I want to save all the values of LeaseNumber in to one comma separated string like $string = "OL/2011/0343 , 184 , OL/2011/0118 , OL/2016/1759"

please help me

$lease = array();
        for($i=0;$i<=count($leaseArray); $i++){
            $lease = $leaseArray[$i]['LeaseNumber'];
        }

我有这个返回数组 p>

  $ leaseArray = Array（  [0] =＆gt;数组（[LeaseNumber] =＆gt; OL / 2011/0343）[1] =＆gt;数组（[LeaseNumber] =＆gt; 184）[2] =＆gt;数组（[LeaseNumber] =＆gt;  OL / 2011/0118）[3] =＆gt;数组（[LeaseNumber] =＆gt; OL / 2016/1759）[4] =＆gt;数组（[LeaseNumber] =＆gt; OL / 2013/0858）[5] =  ＆gt;数组（[LeaseNumber] =＆gt; OL / 2012/0535）[6] =＆gt;数组（[LeaseNumber] =＆gt; OL / 2017/2208）[7] =＆gt;数组（[LeaseNumber] =＆gt;  2355））
  code>  pre> 
 
 我想将LeaseNumber的所有值保存到一个逗号分隔的字符串
like  $ string =“OL / 2011/0343，  184，OL / 2011/0118，OL / 2016/1759“ code>  p> 
 
 
请帮助我 p> 
 
 

  $ lease = array  （）; 
 for（$ i = 0; $ i＆lt; = count（$ leaseArray）; $ i ++）{
 $ lease = $ leaseArray [$ i] ['LeaseNumber']; 
} 
  代码>  pre>

If you want a one-liner then this could work:

$csv = implode( ' , ', array_map( function( $a ){ return $a[ 'LeaseNumber' ]; }, $leaseArray ) );

expanded:

$csv = implode( ' , ', // step 2: implode on ' , ': space-comma-space
    array_map( // step 1: pass $lease array into array_map so that we can get a new array
        function( $a ){ return $a[ 'LeaseNumber' ]; }, // Accept each array in $a and only return the LeaseNumber. array_map will build a new array out of just these values
        $leaseArray // the array to be processed
    )
);

In essence, this is the same as:

$csv = implode( ' , ', array_column( $a, 'LeaseNumber' ) );

but array_map() allows you to transform the data before output/return if you need to.

If you want a one-liner then this is the way

$csv = implode(' , ', array_column($a, 'LeaseNumber'));

As I said in the comments, 1 line, 2 function calls.

One-liners are great but sometimes hard to read. If you want to stick with what you have here are some note

<?php 
$array = array(array("LeaseNumber" => "OL/2011/0343"), array("LeaseNumber"=> 184 ), array("LeaseNumber"=> "OL/2011/0118") , array("LeaseNumber"=> "OL/2016/1759"), array("LeaseNumber"=> "OL/2013/0858"), array("LeaseNumber"=> "OL/2012/0535"), array("LeaseNumber"=> "OL/2017/2208"), array("LeaseNumber"=> 2355));


$lease = array();

//Not equal to the count it starts at 1 not 0
for($i=0;$i<count($array); $i++){
    //lease is an array add to the index not overwrite
    $lease[] = $array[$i]['LeaseNumber'];
}

//You needed to finish with this
$csv = implode(", ",$lease);

echo $csv;

As an fyi switch to a foreach in this case makes life easier:

$lease = array();
foreach($array as $obj){
    $lease[] = $obj["LeaseNumber"];
}
