我正在运行的情况下,我从html
页面提取JSON字符串,将其传递给json_decode
,有时它成功,有时候json_decode
返回null,如何提高我的解决方案是与Qazxswpoi 100%JSON兼容?
这是我提取的字符串,对不起它太长了:json_decode

因为每个人都已经说过你的数据是无效的JSON。它是JavaScript对象但根本不是有效的Json。但是你可以构建自己的假Json解码器。例如,我删除你的数据中的赋值并减少长度......
鉴于这个假Json:
$json_str = html_entity_decode( THE_STRING_FROM_PASTBIN, ENT_QUOTES );
$lots_json = explode( ';', $json_str );
$num_items = count( $lots_json ) - 1;
$lot_json = '';
for( $i = 0; $i < $num_items; ++$i ) {
// $lot_json will have now a valid JSON that can be parse with JavaScript JSON.parse()
$lot_json = str_replace( 'ECAT.lot[\'' . ($i + 1) . '\']=', '', $lots_json[$i] );
$original_lot_json = $lot_json;
// Convert any " to a character chosen by us to not break the JSON format
// but we have to convert it back to '
// ALso convert 's to ***s and than get it back
$lot_json = str_replace( '"', '***', $lot_json );
$lot_json = str_replace( array( "{'", "':", ": '", ":'", "',", ",'", "'}", "['", "']" ),
array( '{"', '":', ': "', ':"', '",', ',"', '"}', '["', '"]' ), $lot_json );
// Convert it back
$lot_json = str_replace( '***', '\'', $lot_json );
$tmp_lot_json = $lot_json;
$lot_json = json_decode( $lot_json, 1 );
if( $lot_json == null ) {
echo 'doGetItemUrlList json_decode fails ' . print_r( $tmp_lot_json, 1 );
echo 'doGetItemUrlList original_lot_json ' . print_r( $original_lot_json, 1 ) );
}
}
你可以构建一个这样的函数:
$fake=<<<'EOL'

;
输出是:
function fakeJsonDecode($data){
return eval('return '.join('',array_slice(array_map(
function($v){
if(is_array($v)){
$v[1]=str_replace('’','"',$v[1]);
$v[1]=str_replace('‘','"',$v[1]);
$v[1]=trim($v[1]);
if(!empty($v[1])&&$v[1][0]==='<'&&$v[1][strlen($v[1])-1]==='>')
$v[1]=substr($v[1],1,-1);
$v=$v[1];
}else{
if($v==='{') $v='[';
if($v==='}') $v=']';
if($v===':') $v='=>';
if($v==='<') $v='"';
if($v==='>') $v='"';
}
return $v;
},token_get_all('<?php '.$data.' ?>')),1,-1)).';');
}
print_r(fakeJsonDecode($fake));
所以你需要在Array
