Sometimes PHP codes may take time for execution. Slow execution time can be due to several reasons. However, here are few tips to speed up PHP code:
1. Filter the database results on the basis of PHP configuration and the database server type. For instance, if the programmer is using a Sybase driver to connect with a MS SQL server, the PHP script can only make use of sybase_fetch_array () and not the sybase_fetch_assoc() function. Programmers can add new functions to speed up the execution time by choosing the type of index to be used, that is, numeric, text or both. By adding new functions, the programmer can spend less time in result processing, namely, weeding out duplicate values that slow down the execution time.
2. Programmers can build new functions that will allow them to consolidate queries and make data access easier. For instance, if a programmer has to build an application to store information in grids, the programmer needs to create an application that does not require manual changing of data when one of the information grids is modified. Creating newer and easily accessible queries will allow the server to process faster and make the program run twice as faster. However, remember not to send too many concatenated string, otherwise the queries might fail.
3. Use pattern matching metrics to determine which of the applications runs faster on PHP script. Create more than two sets of applications from your database library and test run them. Note the time it takes each of the programs to run in milliseconds and which of the programs run faster. After the test run, match the application metrics to determine why one application is faster than the other. By doing this a programmer can develop several PHP applications, run and test them, and use the one that is faster.
These were just basic tips; programmers can develop their own PHP applications to run the scripts faster.
