replica of a text

  • 772

This is my code, I just want to replicate that little text through a for loop.

the result that it gives me is, Holaolalaa I don't understand why it comes out like this.

<?php

$text = "Hola";
$length = strlen($text);

for($i=0;$i<=$length;$i++){

    $rest = substr($text, $i);

   echo $rest;
}

?>
php

  1. It comes out like this for the index of the loop. What you are doing is that it takes the text at the beginning, since the index is 0, it prints the entire word and then it removes a character from the $text variable.

    $text = "Hola"; //texto
$length = strlen($text); //numero de caracters que tiene el texto

for($i=0;$i<=$length;$i++){
  $rest = substr($text, $i); //cogeme el numero de caracters del texto segun i

  echo $rest; //imprime el texto
}

    If you want the word to have 4 characters and to be repeated 4 times you have to do:

    $text = "Hola";
$length = strlen($text);

for($i=0;$i<=$length;$i++){
   echo $text;
}

    If you want to print character by character do the following in the loop:

    for($i=0;$i<=$length;$i++){ 
   echo $text[$i]; //imprime el caracter que toca. 
}

    You can also use str_split, which creates an array with the characters of your string. Then you can go on to read that array character by character.

    For example:

    $text = "Hola";
$textParts=str_split($text);
foreach ($textParts as $char) {
    echo $char.PHP_EOL;
}
