[PHP] RE: Print or Echo takes lots of time
Hi, Thanks for supporting, because of the approaching to the problem, I don't want to change generate once echo once style. And I found solution like this, I split variable into an array and generate loop for printing, mostly fix the problem. And more interesting, some times problem repeates himself. I believe this was connected to php memory performance. Anyhow is there any information about optimal echo or print size ?

Current Total execution time 0.5 seconds. print $strPage; Current Total execution time 2.5 seconds. $strPage carries entire html structure (for example equal of 100K html code); excluding the cookie and other kind of header transfers and error messages, there was no print or echo command was submitted. Is there any idea about this latency and any idea to find problem... You could try echo-ing it out in chunks instead of waiting until the very end. echo/print has to send the data out through the very narrow pipe to Apache - the browser If you send every little snippet one tiny piece at a time, you waste resources. If you wait until the end and send out some huge monster string, you waste resources. Find the balance if you can.

The $ expansion etc. will be done when building the string $strPage, not at the echo stage which is where the OP is seeing the delay.

Plus it's faster in such a marginal sense that you'd have to be doing zillions in a very tight loop to measure it.

I read a while ago that it is more efficient to echo as you go rather than store up a large variable with the content in it. You may want to investigate output buffering instead as 9 times in 10 the sames results of using a big variable can be achieved. It does seem odd none the less tho' that it takes so long.
