Json_string: this parameter is compulsory to specify the JSON encoded string for converting it into PHP objects Json_decode(json_string, asso_arr, recur_depth, opt ) In this article, json_decode() is an inbuilt function provided by PHP for converting or decoding the JSON string into PHP objects where this function takes the JSON data or string which represented as a javascript array as a parameter which is an encoded string is decoded to PHP objects or data types using this json_decode() function and the opposite is done using json_encode() function in PHP. In general, the PHP provides a function that takes a JSON string that usually represents a javascript array or object literals for converting this encoded string in JSON format to a particular PHP object data type. If you do it this way, you can give PHP extra memory only when that piece of code gets called rather than increasing the memory limit for all PHP processes.In PHP the inbuilt function json_decode() function is defined as a function as it name suggest it is a function for conversion of any JSON a standard text format objects or decoding of JSON objects to PHP objects, taking a JSON string as a parameter which this function converts or decodes it and returns the encoded values which were in JSON into proper PHP objects. So how do you do this? Simple - increase the memory limit programmatically early on in your code, before your process runs out of memory. I would never, ever recommend setting the memory limit to -1 (unlimited) in a production environment. You could easily bring a server to its knees if there are many concurrent processes running, each using a high amount of memory. I usually recommend setting the memory limit to something high, like 1GB, assuming you have at least 150% of that free in RAM.Īlso, never do these tests on a production server unless you're sure you have plenty of RAM and you fully understand how web server processes consume memory. Your plan should be to use as little memory as you could practically use where the application works and functions correctly in a production server based on the workload by your users (humans or programmatic). Once you decrease the memory usage you can lower the memory limit it to a value that's more suitable. The goal is to increase the memory to a point where we have the application working again for the purpose of then reducing the memory usage. Note, this is a temporary debugging producedure. Your first course of action is to increase your memory limit. PHP: Fatal Error: Allowed Memory Size of 1073741824 Bytes Exhausted - 1 GB.PHP: Fatal Error: Allowed Memory Size of 536870912 Bytes Exhausted - 512 MB.PHP: Fatal Error: Allowed Memory Size of 268435456 Bytes Exhausted - 256 MB.PHP: Fatal Error: Allowed Memory Size of 134217728 Bytes Exhausted - 128 MB.PHP: Fatal Error: Allowed Memory Size of 67108864 Bytes Exhausted - 64 MB.PHP: Fatal Error: Allowed Memory Size of 33554432 Bytes Exhausted - 32 MB.PHP: Fatal Error: Allowed Memory Size of 16777216 Bytes Exhausted - 16 MB.PHP: Fatal Error: Allowed Memory Size of 8388608 Bytes Exhausted - 8 MB.The size is reported in bytes, though, so we've done some conversions for you: If you aren't sure what your PHP memory limit is set to, it's helpfully included in the error message. There are other causes, but these are much less common - very rarely it can be a memory leak if you're on PHP 5.3 and above. In fact, there are more than 1,300 questions related to PHP memory errors on Stack Overflow alone.ĩ8% of the time this error comes from loading more into memory than what you set up PHP to handle in one process. Out-of-memory errors are one of the most common and hard-to-fix problems that PHP developers run into - especially with applications that process large amounts of data - thanks to PHP's relatively conservative default memory settings.
