Question

我有平面文件，数据用＆＃34;，＆＃34;我需要将值与url进行比较，并仅显示具有相同url值的值

不需要PHP的CSV功能，我想比较并获得结果，如果与url的值最终相同时

csv有4个值，价格，大小，宽度和高度

URL值，发送其他值，但顺序相同（价格，大小，宽度和高度），例如在网址中我使用字符串index.php发送此信息？price = 100＆amp; size = 100＆amp; width = 200＆amp; ;身高= 300 ......等等

例如：

<?php

    $csv_file=file("test.csv");

    for($i=0;$i<sizeof($csv_file);$i++) {

    $exp_csv=explode(",",$csv_file[$i]);

    foreach($exp_csv as $exp_csv2) {
        $csv_end_values[]=$exp_csv2
    }

}


/// By Other side the url 

$exp_url="100,30,400,500";

$exp_url_values=explode(",",$exp_url);


foreach($exp_url_values as $exp_url_values2) {
    $url_end_values[]=$exp_url_values2;
}


/// Finally we have 2 arrays one array with all values we 
get in bucle for csv and by other side values get from url , 
now we need compare url values with values of csv , 
for example if in the url we have only 2 values and no 4 show 
only results with the same of 2 values from url and compare 
in the same order , if when compare the values no the same all , get 0 results 


/// For example values from URL 100,,200,, 
if in csv exists one row with the values 100 and 200 
in the same order show as result and if no , no show 


/// In this point i try use array_difference , 
but no works , because i need compare all values i send by 
url and in the same order 


$aa = array_diff($url_end_values,csv_end_values);


$num_results=0;

foreach($aa as $bb) {
    $num_results++;
}


if ($num_results==0) {
    print "We get Results";
}
else {
    print "No Results";
}

?>

Answer 1

使用fgetcsv（http://php.net/fgetcsv）读取CSV文件而不是普通文件方法。您将获得数组格式，从URL查询字符串中进行比较会更容易。

Answer 2

这是基于我的理解你真正想要的。

$link1 = "index.php?price=150&size=200";
$link2 = "index.php?price=100&size=100";

// separate the string by ampersand to get the get parameters.
$link1ParamsRaw = explode('&',substr(stristr($link1, '?'),1)); // the second param removes all strings from start to ?
$link2ParamsRaw = explode('&',substr(stristr($link2, '?'),1));

$link1Params = array();
$link2Params = array();

foreach($link1ParamsRaw as $param) {
    $param = explode('=',$param); // separate key from value                 
    $link1Params[$param[0]] = $param[1]; // assuming all keys have values
}

foreach($link2ParamsRaw as $param) {
    $param = explode('=',$param); // separate key from value                 
    $link2Params[$param[0]] = $param[1]; // assuming all keys have values
}

$differences = array_diff_assoc($link1Params, $link2Params);

var_dump($differences);
