500 - php curl_exec() method reports 500 error
Jul 06, 2016 pm 01:52 PM
Recently, when using the WeChat QR code scanning payment function of a mall, when the code constructs a WeChat order and then requests WeChat through curl, the curl_exec function reports a 500 error, and no detailed error message is given. There were no problems when using the Alibaba Cloud server and my local test before. Because the customer needs to put the program on the Alibaba Cloud virtual host, this problem occurs. And I confirmed that curl is turned on and can be used. The error displays display_errors and error_reporting has also been set up to display all errors. But:
1. Only 500 errors are displayed and no detailed error information is displayed.
2. The host can only see access logs, but cannot see error logs, nor can it see and modify php.ini settings and apache settings.
3. This error cannot be skipped by using @ and try catch, and the resource parameters of curl are also correct (I have printed each parameter)
In summary, I still haven’t found a way to locate this Wrong, I hope God can guide me.

Generally speaking, the virtual host will let you see the error log, but it may be the last few entries.
I guess the memory limit may be exceeded. Please submit a ticket to ask.
Why not post the code?
Add the following code at the beginning of the php file:
<code>set_error_handler(function(){
echo '<pre class="brush:php;toolbar:false">';
var_dump(func_get_args());
debug_print_backtrace();
},E_ERROR);
set_error_handler(function(\Exception $e){
echo '<pre class="brush:php;toolbar:false">';
echo $e->getFile().PHP_EOL;
echo $e->getLine().PHP_EOL;
echo $e->getMessage().PHP_EOL;
echo $e->getTraceAsString().PHP_EOL;
});</code>

How to get the current session ID in PHP?
Jul 13, 2025 am 03:02 AM
The method to get the current session ID in PHP is to use the session_id() function, but you must call session_start() to successfully obtain it. 1. Call session_start() to start the session; 2. Use session_id() to read the session ID and output a string similar to abc123def456ghi789; 3. If the return is empty, check whether session_start() is missing, whether the user accesses for the first time, or whether the session is destroyed; 4. The session ID can be used for logging, security verification and cross-request communication, but security needs to be paid attention to. Make sure that the session is correctly enabled and the ID can be obtained successfully.
PHP get substring from a string
Jul 13, 2025 am 02:59 AM
To extract substrings from PHP strings, you can use the substr() function, which is syntax substr(string$string,int$start,?int$length=null), and if the length is not specified, it will be intercepted to the end; when processing multi-byte characters such as Chinese, you should use the mb_substr() function to avoid garbled code; if you need to intercept the string according to a specific separator, you can use exploit() or combine strpos() and substr() to implement it, such as extracting file name extensions or domain names.

How to split a string into an array in PHP
Jul 13, 2025 am 02:59 AM
In PHP, the most common method is to split the string into an array using the exploit() function. This function divides the string into multiple parts through the specified delimiter and returns an array. The syntax is exploit(separator, string, limit), where separator is the separator, string is the original string, and limit is an optional parameter to control the maximum number of segments. For example $str="apple,banana,orange";$arr=explode(",",$str); The result is ["apple","bana
JavaScript Data Types: Primitive vs Reference
Jul 13, 2025 am 02:43 AM
JavaScript data types are divided into primitive types and reference types. Primitive types include string, number, boolean, null, undefined, and symbol. The values are immutable and copies are copied when assigning values, so they do not affect each other; reference types such as objects, arrays and functions store memory addresses, and variables pointing to the same object will affect each other. Typeof and instanceof can be used to determine types, but pay attention to the historical issues of typeofnull. Understanding these two types of differences can help write more stable and reliable code.
Using std::chrono in C
Jul 15, 2025 am 01:30 AM
std::chrono is used in C to process time, including obtaining the current time, measuring execution time, operation time point and duration, and formatting analysis time. 1. Use std::chrono::system_clock::now() to obtain the current time, which can be converted into a readable string, but the system clock may not be monotonous; 2. Use std::chrono::steady_clock to measure the execution time to ensure monotony, and convert it into milliseconds, seconds and other units through duration_cast; 3. Time point (time_point) and duration (duration) can be interoperable, but attention should be paid to unit compatibility and clock epoch (epoch)
How to pass a session variable to another page in PHP?
Jul 13, 2025 am 02:39 AM
In PHP, to pass a session variable to another page, the key is to start the session correctly and use the same $_SESSION key name. 1. Before using session variables for each page, it must be called session_start() and placed in the front of the script; 2. Set session variables such as $_SESSION['username']='JohnDoe' on the first page; 3. After calling session_start() on another page, access the variables through the same key name; 4. Make sure that session_start() is called on each page, avoid outputting content in advance, and check that the session storage path on the server is writable; 5. Use ses
