Why Does My PHP Code Cause a 'Fatal Error: Allowed Memory Size of 134217728 Bytes Exhausted' During POS Data Transmission, and How Can I Fix It?

Investigating "Fatal Error: Allowed Memory Size of 134217728 Bytes Exhausted"

Following reports of a "Fatal Error: Allowed Memory Size of 134217728 Bytes Exhausted" encountered during the transmission of POS sales data, we delved into this issue to determine its root cause and provide an effective solution.

It was initially suspected that increasing the PHP memory_limit configuration would resolve the error. However, after experimenting with substantially higher memory limits, the error persisted.

Further investigation revealed that the underlying problem is not solely related to memory limitations but rather a potential memory leak within the PHP code responsible for data transmission. By setting the memory limit to -1, which disables memory restrictions, the server would continue to consume excessive memory, leading to eventual errors.

To rectify the issue effectively, it is crucial to identify and address the memory leak in the PHP code. This can involve using debugging tools, code analysis, and optimizing memory usage within the codebase.

By addressing the memory leak, we can prevent excessive memory consumption and eliminate the occurrence of the "Fatal Error: Allowed Memory Size of 134217728 Bytes Exhausted" encountered during data transmission.
