[英]PHP and AJAX: How can I display json_encode data in PHP while loop?
[英]How can I use json_encode in a while loop?
我的循環問題一直存在。 我要做一個while循環因為我編碼非常大的文件。 但是如果我每行編碼一行,我每次都會創建一個新的JSON對象。
所以現在我有了這個輸出。
[
[
"some logs and soo with informations ",
"00:59:59",
"the pure logssdf"
]
][
[
"some logs and soo with informations ",
"00:59:52",
"the pure logssdf"
]
]
但是我需要這樣的東西:
[
{
"some logs and soo with informations ",
"00:59:52",
"the pure logssdf"
},{
"some logs and soo with informations ",
"00:59:52",
"the pure logssdf"
}
]
使用此代碼,我創建了這個JSON文件:
$jsonFile = fopen('JSONLogs/' . $generatedName, "w");
$handle = @fopen($PATHTOLOG, "r");
if ($handle) {
while (($buffer = fgets($handle, 4096)) !== false) {
$pattern = '/^\w+\s+\d+\s('. preg_quote($SelectedTime) .':\d+.\d+).\d+.\d+\s(.+)/im';
if (preg_match_all($pattern, $buffer, $matches, PREG_SET_ORDER)) {
fwrite($jsonFile, json_encode($matches, JSON_PRETTY_PRINT));
}
else {
}
}
//var_dump($decodeData);
}
fclose($handle);
fclose($jsonFile);
所以我決定制作自己的“編碼器”,並將其寫入文件中。 這是最終的代碼,對我有用。
$jsonFile = fopen('JSONLogs/' . $generatedName, "w");
$i=0;
$handle = @fopen($PathToTMP, "r");
if ($handle) {
fwrite($jsonFile, "[");
while (($buffer = fgets($handle, 4096)) !== false) {
$pattern = '/^\w+\s+\d+\s('. preg_quote($SelectedTime) .':\d+.\d+).\d+.\d+\s(.+)/im';
if (preg_match_all($pattern, $buffer, $matches, PREG_SET_ORDER)) {
if ($i == 0) // Run this if block once.
{
fwrite($jsonFile, '{"0" : "'. $matches[0][0] .'" , '. "\n" . ' "1" : "'. $matches[0][1] .'", '. "\n" . ' "2" : "'. $matches[0][2] .'"}'. "\n" . '');
}
else
{
fwrite($jsonFile, ',{"0" : "'. $matches[0][0] .'" , '. "\n" . ' "1" : "'. $matches[0][1] .'", '. "\n" . ' "2" : "'. $matches[0][2] .'"}'. "\n" . '');
}
$i++;
}
}
fwrite($jsonFile, "]");
//var_dump($decodeData);
}
fclose($handle);
fclose($jsonFile);
