[PHP] rather a mysql question
Sorry that this is more of a mysql question, but since most php programmers use it a lot, i though i might find the answer without subscribing to mysql list, here goes: When i do a query from a big table using indexes,it takes for example 5 seconds. Now if i, after some time repeat the query, the query takes about 0.5 secs. So far i thought it was because of caching, but now i read mysql (v3.23) doesnt support query cache. So this really gets me wondering, where does the speed increase come from? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] regular expression for (NOT 'word')
how would i build a regular expression in php that would match everything but the given word. For example, match the string only if there isnt a word 'php' in the string. I understand i can list characters i dont want to see in the string: [^php]. but this means there cant be any p or h in the string. And ^(php) checks if the string starts with 'php'. How should i do it? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] regular expression for (NOT 'word')
Ok let me explain my problem further some. I need the regular expression to
purify the html page from script tags:
I used: $file = eregi_replace((script(.*).*/script), , $file);
Now this works fine, until theres a webpage like:
script somethingscript data./script
Some webpage data
script somethinganother script data /script
so the regexp above replaces everything between first script and last
/script ie the webpage data also.
So i thought to change the regexp to something like this: $file =
eregi_replace((script(.*)NOT(script)/script), , $file);
where NOT(script) would match everything that contains word script

the best you can do is:
?php
$a = this has php in the string;
if( ! ereg(php, $a ) )
{ print a: not in string; }
$a = this has in the string;
if( ! ereg(php, $a ) )
{ print b: not in string; }

[PHP] PHP output during longer program run times
Lets say i have a script that runs for a longer period of time, 1-10 minutes. Id like the script to give output as to what it is doing while it runs, but the problem is, that it wont print output on runtime, but it will output everything at the same time after it has completed the whole job. Even if i let it to print something out on the first line. Any workaround for this? running php 3.0.12 installed as apache module -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Extracting hyperlinks from file
I need to produce an array of all the links(hrefs) in a remote file (actually those that refer to files in the same remote server, but thats another matter). I'm pretty new to php, i was thinking of doing it with ereg, something like eregi(a href[\]?=(.*), $file, $link); but i cannot think of a way to make it walk through the whole string, so it would find all the links, not just the first one. Any ideas? Ando -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
