php - "break" doesn't work as expected -

i want check string length of comment array. once of them equal or higher 4, want echo relevant value, , stop.

i guessed using while should good, if break loop @ 4 or more, nothing gets echoed. if break @ 5 or more, previous 2 4-string values echoed, want first 4-string value echoed, , stop.

$comment[1] = "abc";  // add comment below text button $comment[2] = "xyz";  // add comment below text button $comment[3] = "abcd";  // add comment below text button $comment[4] = "xyza";  // add comment below text button $comment[5] = "abcde";  // add comment below text button $comment[6] = "xyzab";  // add comment below text button  $x = 1;  while ($x <= 10) {      if (strlen((string)$comment[$x]) >= 4 ) {          echo $comment[$x];         echo "<br/>";      }      $x = $x + 1;      if (strlen((string)$comment[$x]) >= 4) break; // nothing echoed   // if (strlen((string)$comment[$x]) >= 5) break; // 2 values echoed  }  

also, there maybe better/shorter practice check thing, maybe built in function in_array?

the problem code loop body checks/prints 1 element , breaks on different 1 because increment pointer between 2 points. have moved break statement above increment, or put if statement (much @a-2-a suggested). should work expected.

with break above increment:

while ($x <= 10) {      if (strlen((string)$comment[$x]) >= 4 ) {          echo $comment[$x];         echo "<br/>";      }     if (strlen((string)$comment[$x]) >= 4) break;       $x = $x + 1; }  

with combined echo/break:

while ($x <= 10) {      if (strlen((string)$comment[$x]) >= 4 ) {          echo $comment[$x];         echo "<br/>";         break;      }      $x = $x + 1; }  

also may want iterate array it's length instead of hardcoded limit of 10:

$x = 0; $length = count($comment);  while ($x < $length) {    // ...  }
