[SOLVED] how to select only a specifc amount of words from a variable

[phpQuestioner]

how can you only pull out 3 words from a variable? then how would you pull 3 other words from your variable besides the original first 3 words?

[sspoke]

you should say like..

how do you know they are words? do they have delimiters or maybe size related to split the words?

 

I dont think php knows if they are words or not. 

 

 

or u mean http://us2.php.net/language.variables.variable  ?

Have you thought to turn your variable into an array using expode()?

 

Then you just pull out what ever words you want, if you do it logically, you can keep track of the words already output.

[phpQuestioner]

not exactly what I meant; I know that I can use an explode, but I do not want to explode this variable until I get to a specific place in the variable. I would like to display the first 3 words in the variable and then display 3 more words from this variable in a different area of my page.

 

like this:

<?php

echo "<table><td>";

$myvar="this is a string that I want to dissect ";
$seperate = explode(" ", $myvar, 3);
for($i = 0; $i < count($seperate); $i++){
echo "<li>$seperate[$i]</li>";
}

echo "</td><td>";

// then some where else in my page pull 3 more addition words from this variable

$myvar="this is a string that i want to dissect ";
$seperate = explode(" ", $myvar, 3);
for($i = 0; $i < count($seperate); $i++){

// only this time I want to echo the next 3 words from this variable here and exclude the 3 words above that I have already pulled out from this variable

}

echo "</td></table>";

?>

 

 

you see what I am saying..............?

Why can't you just:

 

<?php

echo "<table><td>";

$myvar="this is a string that i want to dissect ";
$seperate = explode(" ", $myvar);
echo "<li>$seperate[0]</li><li>$seperate[1]</li><li>$seperate[2]</li>";


echo "</td><td>";

// then some where else in my page pull 3 more addition words from this variable


// only this time I want to echo the next 3 words from this variable here
echo "<li>$seperate[3]</li><li>$seperate[4]</li><li>$seperate[5]</li>";

}

echo "</td></table>";

?>

<?php

echo "<table><td>";

$myvar="this is a string that i want to dissect ";
$seperate = explode(" ", $myvar);
for($i = 0; $i < count($seperate); $i++){
echo "<li>$seperate[$i]</li><li>$seperate[$i+1]</li><li>$seperate[$i+2]</li>";
echo "</td><td>";
}


echo "</td></table>";

?>

[phpQuestioner]

probably because you left out the for loop; because I just tested that and there's an error in this syntax because noting displays

[phpQuestioner]

sspoke - I just tested your code to; their is an error in your syntax too. because nothing displays in the page with this code in it.

[tidalik]

Not quite understanding you there phpQuestioner...

 

But I did forget to take out an extra }

<?php

echo "<table><td>";

$myvar="this is a string that i want to dissect ";
$seperate = explode(" ", $myvar);
echo "<li>$seperate[0]</li><li>$seperate[1]</li><li>$seperate[2]</li>";


echo "</td><td>";

// then some where else in my page pull 3 more addition words from this variable


// only this time I want to echo the next 3 words from this variable here
echo "<li>$seperate[3]</li><li>$seperate[4]</li><li>$seperate[5]</li>";



echo "</td></table>";

?>

[sspoke]

<?php

echo "<table><td>";

$myvar="this is a string that i want to dissect ";
$seperate = explode(" ", $myvar);
for($i = 0; $i < count($seperate); $i++){
echo "<li>".$seperate[$i]."</li><li>".$seperate[$i+1]."</li><li>".$seperate[$i+2]."</li>";
echo "</td><td>";
}


echo "</td></table>";

?>

 

Fixed
