Search File for Strings

Hey,

I would like to know how to open a txt file and search it using PHP and record every string between the following 2 strings:

1. ><a href="/cool/of/
2. /"><img src="/awesome.gif"

Then create a new txt file with each string found on a new line

 

At first you saywhat you want to search from the text file content.

 

Well inbetween those 2 strings are usernames, i need to list them all from the file by removing them from the source

 

$searchIn = file_get_contents('somefile.txt');
preg_match_all('@><a href="/cool/of/(.*?)/"><img src="/awesome\.gif"@',$searchIn,$matches,PREG_SET_ORDER);
$userNames = $matches[0];
unset($matches);
$saveAs = implode("\n\r",$userNames);
file_put_contents('usernames.txt',$saveAs);

PHP:

Untested but along those lines.

 

Fatal error: Call to undefined function: file_put_contents()

Doesnt quite work using PHP 4.4.3

 

if(!function_exists("file_put_contents"))
{
function file_put_contents( $file, $data )
{
$handle = fopen( $file, "w+" );
$write = fwrite( $handle, $data );
fclose( $handle );
return $write ;
}
}

 

Add that to the existing code? Dont i need to define file etc?

 

add it to ( above ) the code

 

<?php
function put_strings( $infile, $outfile )
{
	if(!($search = file_get_contents( $infile ))):
		print("Cannot retrieve $infile<Br/>\n");
		return false;
	endif;
	preg_match_all( '#<a href="/cool/of/(.*?[^/])/">#si', $search, $found );
	if( $found ):
		$handle = fopen( $outfile, "w+" );
		if( !$handle ):
			print( "Cannot open $outfile for writing<br/>\n" );
			return false;
		endif;
		$write = fwrite( $handle, implode("\r\n", $found[1] ) );
		fclose( $handle );
	endif;
	
	return !$write ? false : count( $found[1] ) ;
}
if( !put_strings( 'test.php', 'out.txt' ) ):
	echo "CAN'T<br/>\n";
else:
	echo "DONE<br/>\n";
endif;
?>
