What is PHP memory limit and why do you need them?
The PHP memory limit is the maximum server memory each PHP script can extend. Per the PHP documentation: “This sets the memory in bytes that a script is allowed to designate. This makes a difference in preventing ineffectively composed scripts from eating up all accessible memory on a server.”
The memory limit setting fixes a memory size for executing a script. It prevents ineffectively coded scripts on the server that designate superfluous space, thus sparing server memory during large-scale utilization of the application.
What is the PHP Memory Limit?
The PHP memory_limit is per-script, just as a standard memory limit that is enough for any web application. A lower setting of 128M. If PHP scripts attempt to utilize more than 128M, those scripts would presently return memory limit surpassed errors.
Set the memory limit set by executing the phpinfo() function to see the memory constrain and plan your server setting according to the value. The server administrator can set a memory limit from -1—no memory assignment to any measure.
PHP scripts are tiny. Every individual script should only take up a small amount of RAM, unless you’ve got an unusual application that needs more resources in one script than most programs will ever take in their entirety. These kinds of plugins certainly exist, but they’re uncommon.
Why Is There a Memory Limit?
Increasing the memory of each process can decrease the number of concurrent processes that can run. PHP processes are critical to the maximum number of page requests you’ll serve at any given time.
When PHP processes get overloaded, the memory limit, servers have to force stop before they completely crash, or all your distributed resources for the month get consumed.

Cloudways handle server management for you so you can focus on creating great apps and keeping your clients happy.
How Does PHP Memory Limit Relate to Performance?
Say 3 PHP scripts are utilizing 100 MB of memory each at the same time. That would add up to 300 MB of memory utilization, and a PHP limit of 128 MB wouldn’t be enough. The RAM depends on the accessibility of the data required to run a preparation or script. So if you know you’ll require more, 256 MB should cover the heaviest plugins.
Be careful when using plugins that need additional memory. Some web hosts set the PHP memory limit exceptionally low, so that can cause the mistake to appear even when you’re not installing a power-hogging application.
How to Increase the PHP Memory Limit
If your website’s needs necessitate increasing the memory limit, to complete a process, for instance, you’d need to create a php.ini (phprc) file and increase the limit there.
But Cloudways users don’t need to edit the PHP. ini file and wp-config file. They can just change the value from within the application settings using the Cloudways Platform.
