PHP crawls arrays on the page and cyclically outputs them online.

PHP captures the array on the page and cyclically outputs the urgent online content. I used file_get_contents () to capture the content on this website.
Http://simonfenci.sinaapp.com/index.php? Key = simon & wd = 1314abc

It seems that an array is reversed .. However, no matter how you use the foreach loop, an error is reported ..

I just want to retrieve the values in the word in the array .. Who can help me?

Reply to discussion (solution)

You get a string. So you certainly don't need foreach.

Obtain the regular value or other methods in word.

$s = file_get_contents('http://simonfenci.sinaapp.com/index.php?key=simon&wd=1314abc');preg_match_all('/\[word\] => (.+)/', $s, $m);print_r($m[1]);

Array(    [0] => 1314    [1] => abc)

$s=file_get_contents('http://simonfenci.sinaapp.com/index.php?key=simon&wd=1314abc');$rule='#(?<=\[word\] =>)\s\w+#';preg_match_all($rule,$s,$arr);print_r($arr);

Array(    [0] => Array        (            [0] =>  1314            [1] =>  abc        ))

File_get_contents () captures the page and returns a string.

If you need to call through a remote interface, we recommend that you http://simonfenci.sinaapp.com/index.php? The output of key = simon & wd = 1314abc can be changed to a string in json format.

Use json_decode to decode the content obtained at the call to obtain the php array.

In addition, it is not recommended to use file_get_contents to obtain the content of a remote webpage. curl is recommended.

Http://simonfenci.sinaapp.com/index.php? Key = simon & wd = 1314abc
The returned result is:
String (247) "Array ([0] => Array ([word] => 1314 [word_tag] => 90 [index] => 0) [1] => Array ([word] => abc [word_tag] => 95 [index] => 1 ))"

// A string with an array structure instead of an array

// Encoding

$arr = array(    0=>array(        'word '=> 1314,        'word_tag'=> 90,        'index' => 0    ),    1 => Array(        'word' => 'abc',        'word_tag' => 95,        'index' => 1    ));echo( json_encode($arr) );

// Decoding

$arr    = array();$url    = 'http://simonfenci.sinaapp.com/index.php?key=simon&wd=1314abc';$ch     = curl_init();curl_setopt($ch, CURLOPT_URL, $url);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);curl_setopt($ch, CURLOPT_HEADER, 0);$output = curl_exec($ch);$arr    = json_decode($output,true);curl_close($ch);

You can also use the serialize () and unserialize () serialization functions to replace json.

Supplement:

// Json returned string
[{"Word": 1314, "word_tag": 90, "index": 0 },{ "word": "abc", "word_tag": 95, "index ": 1}]

// String returned by serialize
A: 2: {I: 0; a: 3: {s: 5: "word"; I: 1314; s: 8: "word_tag"; I: 90; s: 5: "index"; I: 0;} I: 1; a: 3: {s: 4: "word"; s: 3: "abc"; s: 8: "word_tag"; I: 95; s: 5: "index"; I: 1 ;}}

Obviously, the output is shorter than the direct var_export ($ val, true); and can be easily restored.

Thank you for your consideration.
