preg_match_all wount find all matches ?

[chrisdee]

Hello. Im having trouble with preg_match_all. Im trying to
make preg find all instances of test in a string, and then
print out how many it found with a for loop. The problem is
that only three test's are printet out. There are six in total.

Below is the script :

<? 

$text1 = "Test 1, test 2, test 3, test 4, test 5, test 6"; 
for ($t=0; $t<count($text1); $t++) { 
  preg_match_all("/test/i", $text1, $match1); 
  print "<br>".$match1[0][$t]; 
} 
echo "<hr>"; 

?> 

What am I doing wrong ?

Hi,

Looks like you've just got mixed up a bit ...

<?php
$text1 = "Test 1, test 2, test 3, test 4, test 5, test 6";  

// preg_match_all should only be called once.
preg_match_all("/test/i", $text1, $match1);  

// $match1[0] is the array of 'full' matches, so count and use them ...

$full_matches = $match1[0];
$num_matches = count($full_matches);

for ($t=0; $t < $num_matches; $t++) {  

	print "<br>".$full_matches[$t];  

}  

echo "<hr>";  

?>
