This article analyzes the solution to the batch task processing without timeout in PHP. Share it for your reference, as follows:
PHP batch task processing
PHP will time out when batch processing tasks. In fact, the solution is very simple. It is to split the task and process part of it at a time. The task progress can be placed on the server or on the client. If it is not very complicated, it is placed on the client and used js to process it.
Client js callback processing
When the client processes, you need to live in a place, that is, when using ajax, ajax is asynchronous, and when using a for loop to process, it is just a batch request. In this way, when the task is large, it will directly DDOS server, so you need to wait for the callback function to return and then make the next request.
Client Example
document:
<!DOCTYPE html>
<html>
<head>
<title></title>
<script type="text/javascript" src="/jquery/1.11.3/"></script>
<script type="text/javascript">
$(function(){
$("#Jidsall").click(function(){
$(".Jids").prop("checked", );
});
$("#btn_request").click(function(){
// Task Object var task = {};
// Task list = $(".Jids:checked").toArray();
// Current task = 0;
// Next request = function() {
if ( >= ) {
// Mission completed ();
return;
}
var i = ;
// Request failed var error = function(data){
// The logic of failure ("error", );
// Continue to call ();
};
// Request succeeded var success = function(data){
// Logic of success ("success", );
// Continue to call ();
};
$.ajax({
context: this,
method: "post",
url: "",
data: {id:[i].value},
error: error,
success: success,
dataType: "json"
});
++;
};
// Complete the request = function() {
("done");
};
// ask ();
});
});
</script>
</head>
<body>
<table>
<tr><td><input type="checkbox" >all</td></tr>
<tr><td><input type="checkbox" value="1" class="Jids">1</td></tr>
<tr><td><input type="checkbox" value="2" class="Jids">2</td></tr>
<tr><td><input type="checkbox" value="3" class="Jids">3</td></tr>
<tr><td><input type="checkbox" value="4" class="Jids">4</td></tr>
<tr><td><input type="checkbox" value="5" class="Jids">5</td></tr>
<tr><td><input type="checkbox" value="6" class="Jids">6</td></tr>
<tr><td><input type="checkbox" value="7" class="Jids">7</td></tr>
<tr><td><input type="checkbox" value="8" class="Jids">8</td></tr>
<tr><td><input type="checkbox" value="9" class="Jids">9</td></tr>
<tr><td><input type="button" value="ask"></td></tr>
</table>
</body>
</html>
Example of PHP processing batch tasks Server side example
document:
<?php
sleep(3);
if ($_POST["id"] == 5) {
http_response_code(500);
exit();
}
echo json_encode($_POST);
