PHP crawls the array on the page and loops out the emergency line etc.

I used file_get_contents () to crawl the content on this web site.
Http://simonfenci.sinaapp.com/index.php?key=simon&wd=1314abc

It appears as if the inverse is an array: But I don't know how to use the Foreach loop to give an error.

I just want to take the value out of the word in the array. Somebody help me, hurry.

What you get here is a string. So definitely don't use foreach.

Get a regular or other method of face value in Word.

$s = file_get_contents (' http://simonfenci.sinaapp.com/index.php?key=simon&wd=1314abc ');p reg_match_all ('/\[ Word\] = (. +)/', $s, $m);p rint_r ($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+# ';p reg_match_all ($rule, $s, $arr);p Rint_r ($arr);

Array (    [0] = = Array        (            [0] = =  1314            [1] = =  ABC        ))

The file_get_contents () Fetch page returns a string.

If you need to call through a remote interface, it is recommended that the output of http://simonfenci.sinaapp.com/index.php?key=simon&wd=1314abc be changed to a JSON-formatted string.

The PHP array can be obtained by decoding with Json_decode when the content is fetched at the call.

Also, it is not recommended to use file_get_contents to get the contents of a remote Web page, curl is recommended.

Http://simonfenci.sinaapp.com/index.php?key=simon&wd=1314abc
The returned is:
String (247) "Array ([0] = = Array ([Word] = 1314 [Word_tag] = [index] = 0) [1] = = Array ([Word] =& Gt ABC [Word_tag] = [index] = 1) "

A string of an array structure, not an array

Coding

$arr = Array (    0=>array (        ' word ' = = 1314, ' word_tag ' = ' = ',        ' index ' = 0    ),    1 = Array (        ' word ' = ' abc ',        ' word_tag ' = ' + ',        ' index ' = 1    ); Echo (Json_encode ($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 replace the JSON with serialize () and Unserialize (), the serialization function.

Add:

String returned by JSON
[{"word": 1314, "Word_tag": +, "index": 0},{"word": "abc", "Word_tag": Up, "index": 1}]

Serialize the returned string
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;}}

Significantly more than direct Var_export ($val, true); The output is shorter and can be easily restored.

Thank you, and finally it's done.
