如何使用格式化的 html 设计循环遍历 php 中的数组？

Question

I want to loop through an array with formatted HTML that set up before. For ex:

$display_format = "%address%<br>%zipcode% %city%<br>&euro; %price% / %m2% m2"

And I have an array like this:

$array_display = array (array ( 'address' => 'Prins Hendriklaan 15','zipcode' => '1075', 'city' => 'Amsterdam', 'price' => 6750000, 'm2' => 428 ), array ( 'address' => 'Huizingalaan', 'zipcode' =>'187 189-191', 'city'=> Amsterdam, 'price' => 3000000, 'm2' => 1.155) )

so I want to loop through $array_display and display each row into the formated design from $display_format. And most importantly, when I update the order or add more field or format of $display_format then it would be changed accordingly from the loop of array, no hardcode when looping through array for fixed field order( this is the most difficult part).

Can anybody help me to do this?

Thanks a lot.

After correcting the small mistook about the unquote value - Amsterdam '-) you can use preg_replace with a pattern based upon the array keys found in the source data ($array_display)

<?php

    $array_display = array ( 
        array (
            'address'   => 'Prins Hendriklaan 15',
            'zipcode'   => '1075',
            'city'      => 'Amsterdam',
            'price'     => 6750000,
            'm2'        => 428
        ), 
        array (
            'address'   => 'Huizingalaan', 
            'zipcode'   => '187 189-191', 
            'city'      => 'Amsterdam', 
            'price'     => 3000000, 
            'm2'        => 1.155
        )
    );
    
    
    $display_format = "%address%<br>%zipcode% %city%<br>&euro; %price% / %m2% m2";
    
    foreach( $array_display as $i=>$arr ){
        $keys=array_keys( $arr );
        $tmp=$display_format;
        foreach( $keys as $key ){
            $pttn=sprintf('@%%%s%%@',$key);
            $tmp=preg_replace($pttn,$arr[$key],$tmp);
        }
        echo $tmp;
    }

?>

Which yields:

Prins Hendriklaan 15
1075 Amsterdam
€ 6750000 / 428 m2Huizingalaan
187 189-191 Amsterdam
€ 3000000 / 1.155 m2

Answer 2

There's a typo in your array data 'city' => Amsterdam , fixed that to 'city' => 'Amsterdam' .

Loop through the array, $placeholders = array_map(function($value) { return "%$value%"; }, array_keys($display)); will create a list of values to replace from your array keys ( %address% , %city% ...), then replace them with the actual values from the arrays.

This code does not check for existence of the "placeholders" in your $display_format

$display_format = "%address%<br>%zipcode% %city%<br>&euro; %price% / %m2% m2";
$array_display = array (array ( 'address' => 'Prins Hendriklaan 15','zipcode' => '1075', 'city' => 'Amsterdam', 'price' => 6750000, 'm2' => 428 ), array ( 'address' => 'Huizingalaan', 'zipcode' =>'187 189-191', 'city'=> 'Amsterdam', 'price' => 3000000, 'm2' => 1.155) );

foreach ($array_display as $display) {
    $placeholders = array_map(function($value) { return "%$value%"; }, array_keys($display));
    echo str_replace($placeholders, $display, $display_format);
}

<?php

$array_display = array( array ( 'address' => 'Prins Hendriklaan 15','zipcode' => '1075', 'city' => 'Amsterdam', 'price' => 6750000, 'm2' => 428 ), array ( 'address' => 'Huizingalaan', 'zipcode' =>'187 189-191', 'city'=> 'Amsterdam', 'price' => 3000000, 'm2' => 1.155) );

foreach($array_display as $displayItem) {
    $display_format = "{$displayItem['address']}<br>{$displayItem['zipcode']} {$displayItem['city']}<br>&euro; {$displayItem['price']} / {$displayItem['m2']} m2";
}

Edit: made a solution that didn't work
