Question

我的PHP代码是

public function getAllAttributes()
    {
        $this->dao->select('b_title');
        $this->dao->from($this->getTable_buttonsAttr());
        $result = $this->dao->get();
        if( !$result ) {
            return array() ;
        }
        return $result->result();
    }

$details = Modelbuttons::newInstance()->getAllAttributes();
$string = implode(', ', $details);
var_dump ($string) ;  ?>

我得到一个看起来像这样的数组：

 array (size=6)
          0 => 
            array (size=1)
              'b_title' => string 'test 10' (length=12)
          1 => 
            array (size=1)
              'b_title' => string 'test 11' (length=12)
          2 => 
            array (size=1)
              'b_title' => string 'test 12' (length=13)
          3 => 
            array (size=1)
              'b_title' => string 'test 13' (length=8)
          4 => 
            array (size=1)
              'b_title' => string 'test 14' (length=14)
          5 => 
            array (size=1)
              'b_title' => string 'test 15' (length=32)

如何使用PHP将此数组转换为这样的字符串？

$out = '10, 11, 12, 13, 14,15';

Answer 1

您可以尝试使用此代码。

$array = [['b_title' => 'test 10'],['b_title' => 'test 11']];
foreach($array as $a) {
    $values[] = explode(' ', $a['b_title'])[1];
}
echo implode(', ', $values);

Answer 2

基本示例：

<?php
// your array
$array = array(
        array('b_title'=>'test 10'),
        array('b_title'=>'test 11'),
        array('b_title'=>'test 12'),
        array('b_title'=>'test 13')
    );

$newArr = array();
foreach ($array as $key => $value) {
    $newVal = explode(" ", $value['b_title']);
    $newArr[] = $newVal[1];
}
echo implode(',', $newArr); // 10,11,12,13
?>

<强>解释

首先使用explode()作为字符串值，帮助您根据需要拆分字符串：

$newVal = explode(" ", $value['b_title']);

您可以将索引1存储在数组中：

$newArr[] = $newVal[1]; // array(10,11,12,13)

最后，您只需使用implode()函数来帮助您获取逗号分隔数据。

echo implode(',', $newArr); // 10,11,12,13

Answer 3

另一种方法。

$details = Modelbuttons::newInstance()->getAllAttributes(); /*[['b_title' => 'test 10'],['b_title' => 'test 11']];*/
$token = "";
foreach($details as $row1){
 $token = $token.$row1['b_title'].", ";
}
echo rtrim(trim($token),",");

输出：测试10，测试11

<强> 解释

通过foreach，所有数组值现在都以逗号分隔。

截至目前，输出将为test 10, test 11,。因此，最后通过rtrim()删除额外的逗号。

import { Component, OnInit } from '@angular/core';
import { HttpService } from 'services/http.service'

@Component({
    selector: 'my-analytics',
    styleUrls: ['../../../node_modules/@telerik/kendo-theme-default/dist/all.css'],
    template: require('./analytics.component.html')

})
export class AnalyticsComponent implements OnInit {

    private gridData: any[] = [{
        "ProductID": 1,
        "ProductName": "Chai",
        "UnitPrice": 18.0000,
        "Discontinued": false,
        "Category": {
            "CategoryID": 1,
            "CategoryName": "Beverages",
            "Description": "Soft drinks, coffees, teas, beers, and ales"
        }
    }, {
        "ProductID": 2,
        "ProductName": "Chang",
        "UnitPrice": 19.0000,
        "Discontinued": false,
        "Category": {
            "CategoryID": 1,
            "CategoryName": "Beverages",
            "Description": "Soft drinks, coffees, teas, beers, and ales"
        }
    }, {
        "ProductID": 3,
        "ProductName": "Aniseed Syrup",
        "UnitPrice": 10.0000,
        "Discontinued": false,
        "Category": {
            "CategoryID": 2,
            "CategoryName": "Condiments",
            "Description": "Sweet and savory sauces, relishes, spreads, and seasonings"
        }
    }];

    constructor(private http_service: HttpService) { }

    ngOnInit() {

    }
}

这给出了你想要的结果。虽然在操作等之前检查数组的格式是否正确，但它可以在那里做一些条件。

Answer 5

有很多方法可以给这只猫上皮 - 这是一个：

<?php
$out = '';

foreach ($array as $arrayItem) {
    $out .= $arrayItem['b_title'] . ', ';
}

// Remove the extraneous ", " from the $out string.
$out = substr($out, 0, -2);
?>

或者，如果您还想删除＆＃34;测试＆＃34; “b_title”的一部分＆＃39; b_title＆＃39;关键的价值;然后你可以像这样完成它：

<?php
$out = '';

foreach ($array as $arrayItem) {
    $out .= str_replace('test ', '', $arrayItem['b_title']) . ', ';

}

// Remove the extraneous ", " from the $out string.
$out = substr($out, 0, -2);
?>

Answer 6

$test_array = array(
  0 => array('b_title' => 'test 10'),
  1 => array('b_title' => 'test 11'),
  2 => array('b_title' => 'test 12'),
  3 => array('b_title' => 'test 13'),
  4 => array('b_title' => 'test 14'),
  5 => array('b_title' => 'test 15'),
);
$result = "";
$result1 = array_walk($test_array, function ($value, $key) use(&$result) {
    $result .= ",".array_pop(explode(" ", reset($value))).",";
    $result = trim($result, ",");
});

输出：$ out =＆＃39; 10,11,12,13,14,15＆＃39;;

<强>解释

使用PHP的本机array_walk（）迭代数组，这将减少forloops，然后使用explode（），array_pop（）和trim（）来准备数组，这可能是准备所需字符串所必需的。

Answer 7

你也可以尝试这个

$check  = array(array ('b_title' => array('test 10'))
    ,array('b_title' => array('test 11'))
    ,array('b_title' => array('test 12'))
    ,array('b_title' => array('test 13'))
    ,array('b_title' => array('test 14'))
    ,array('b_title' => array('test 15')));

$srt = "";
foreach($check as $kye => $val)
{
    $title = $val['b_title'][0];
    $var = explode(' ',$title);
    $srt .= trim($var[1]).', ';
}
$srt = substr(trim($srt),0,-1);

Answer 8

您可以使用上述网址解决方案Click here

foreach ($arr as $k=>$val) {
    $v = explode (' ', $val['b_title']);
    $out .= $v[1].',';
}
$out = rtrim ($out, ',');
echo '<pre>'; print_r($out); die;

Answer 9

试试这个，

foreach($test_array as $val)
{
  $new_array[] = preg_replace('/\D/', '', $val['b_title']);
}

$out = implode(',', $new_array);
echo $out;

<强>输出

10,11,12,13,14,15
