SUMMARY

This discussion focuses on logging SQL statements into a MySQL table to aid in debugging PHP applications. The primary issue identified is the occurrence of MySQL syntax errors when attempting to insert values containing apostrophes. The solution provided involves doubling apostrophes in the SQL statements to prevent syntax errors during insertion. This method ensures that the SQL statements are correctly interpreted by MySQL, facilitating effective logging for debugging purposes.

Goal: I seek to log the SQL statements into a MySQL table, with the time they were executed as an aid to debugging problems with PHP apps I am writing.

Problem: MySQL seems to try to interpret the statement, meant to simply be data in a field. When I try to "INSERT" the values, I get MySQL syntax errors.

Solution: Does anyone have a way around this problem?

Do your inserts have apostrophes? You'll need to double them (replace ' with '').
