Xampp-phpmemory_limit limitations

I used Xampp to build the testlink environment. the following error is prompted when I export a brief test report: Fatalerror: partition (triedtoallocate8925bytes) inD: xampphtdocstestlinklibresultsresultsTC. phponline586 this is an error reported after I changed the memory_limit limit to MB. the prompt log should be a memory limit change... phpxampp

I used Xampp to build the testlink environment. the following error is prompted when I export a brief test report recently:
Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 8925 bytes) in D: \ xampp \ htdocs \ testlink \ lib \ results \ resultsTC. php on line 586

This is an error reported after I changed the memory_limit limit to MB. The Log from the prompt should be changed to the memory limit to MB, but MB of memory cannot be allocated during allocation. Therefore, an error is reported, how can I modify it?
