如何处理这个字符串并从中提取数据

Question

$string='eDreams 459   Travel Up 464   AirAfrica 464   Available at  459  Available at  464  Available at  464  Available at  473  Available at  478  Available at  479  Available at  498';
how to get data like:
array =
  0 => string 'eDreams' (length=6)
  1 => string '459'
array=
  0 => string 'Travel Up' (length=6)
  1 => string '464'
array = 
  0 => string 'AirAfrica' (length=6)
  1 => string '464'

怎么做我用爆炸试过了它工作正常但不准确请帮助我？

Answer 1

您想要隔离到单独数组中的元素似乎由多个 space 或制表符分隔，并且数组元素本身由单个 space 分隔。如果字符串实际上采用这种格式，您可以使用 split() 函数将这些元素拉入一个或多个数组。例如：

$split_pattern = "   ";
$array = split($split_pattern, $string);

这将生成如下所示的数组：

array =
   0 => string 'eDreams 459'
   1 => string 'Travel Up 464'
   ...
   4 => string 'Available at'
   5 => string '459'
   etc...

您将需要再次 split() 每个数组元素以创建格式为 0 => name, 1 => number 的数组。

要处理 available at 条目，您可以使用 array_keys() 函数：

$pattern = "Available at";
$availables = array_keys($array, $pattern);
foreach ($availables as $available){
    $availableAt = $array[$available];
    $availableNum = $array[$available + 1];
}

那么 $availableAt 将始终是 "Available at"，但 $availableNum 将包含数字，它只是您最初 split() 数组中的下一个元素。有几种方法可以完成此操作，但我认为这是最清楚的。

我找到了一个方法..它并不漂亮。希望对你有帮助。

<?php
$string = "eDreams 459   Travel Up 464   AirAfrica 464   Available at  459  Available at  464  Available at  464  Available at  473  Available at  478  Available at  479  Available at  498";
$array = explode(" ", $string);
$final_array = array();
$found = false;
foreach ($array as $value) {
    if (ctype_digit($value)){
        $final_array[count($final_array)-1][] = (int)$value;
        $found = false;
    } else {
        if ($found == false){
            $final_array[] = array($value);
            $found = true;
        } else {
            $final_array[count($final_array)-1][0] .= " " . $value;
        }
    }
}
print_r($final_array);
?>

我不会用这样的东西。也许你可以直接从数据库中得到更好的结果。

我想到了这个解决方案...

$string = 'eDreams 459   Travel Up 464   AirAfrica 464   Available at  459  Available at  464  Available at  464  Available at  473  Available at  478  Available at  479  Available at  498';

$arr = [ ]; 

$name = '';

$number = '';

$count = strlen( $string );

$reset = 0;

for ( $i = 0; $i < $count; $i++ )
{
    if ( is_numeric( $string[ $i ] ) )
    {
        $reset = 1;
        $number.= $string[ $i ];
    }
    else
    {
       if ( $reset == 1 )
        {
            $arr[] = [ trim( $name ), trim( $number ) ];
            $name = '';
            $number = '';
            $reset = 0;
        }
        else
        {
            $name.= $string[ $i ];
        }
    }
}
print_r( $arr );

试试这个：

$string = "eDreams 459   Travel Up 464   AirAfrica 464   Available at  459  Available at  464  Available at  464  Available at  473  Available at  478  Available at  479  Available at  498";
$array = explode(" ", $string);
$final = [];

$str= [];
$num =[];

$temp = $array;
foreach($temp as $k=> $v){
    if(!empty($v)){ 
        if(is_numeric($v)){
            $num[] = $v;
            $final_array[] =[
                implode(" ",$str),implode(" ",$num)    
            ];

            $str= [];
            $num =[];
        }else{
            $str[] = $v;
        }
        $temp[$k] = "";
    }
}

print_r($final);
