BBGaming Posted August 10, 2007 Share Posted August 10, 2007 I'm trying to find a way to search a text file for a certain key, and there will be one key on each line. I'm hoping it could return 0 if there's no match, and 1 if there is. I'm familiar with this in other languages, but I can't find how in PHP you can read a certain line of a file. I can get most of the code already: $var=0; for($i=1;$i<=file_lines();$i+=1) { if (file_read_line()=="key") { $var=1; } } But I'm sure you spot two probmlems, they are file_lines() and file_read_line(). Does anybody know the proper replacements, or a simpler way? Thanks! Link to comment https://forums.phpfreaks.com/topic/64281-check-file/ Share on other sites More sharing options...
Fadion Posted August 10, 2007 Share Posted August 10, 2007 If im getting right what u wanna do, u can use the following code: $file = file('file.txt'); foreach($file as $line){ if(strstr($line, $key)){ echo 'Key founded'; } } file() passes all the file lines to the array $file, then in the loop i used strstr() to find if there is a $key in each line. Hope it is what u were searching for. Link to comment https://forums.phpfreaks.com/topic/64281-check-file/#findComment-320468 Share on other sites More sharing options...
