How I can get $lorem_text as a new string $lorem_outside_text without changing $lorem_text?

for ($i = 0; $i <= 5; $i++) {
  $lorem_text = "lorem\n";
}

$lorem_outside_text = $lorem_text;

echo $lorem_outside_text;

Now result is: lorem

Result should be: lorem lorem lorem lorem lorem

With this piece of code you are overwriting your existing value every time.

for ($i = 0; $i <= 5; $i++) {
  $lorem_text = "lorem\n"; // this just overwrites $lorem_text value 6 times with same value
}

Instead try to concatenate it using . and also remove extra using of variables here $lorem_outside_text

$lorem_outside_text = ''; //intialize it as empty string
for ($i = 0; $i <= 5; $i++) {
  $lorem_outside_text .= "lorem\n";
}
echo $lorem_outside_text;

Pretty Neat:

<?php
echo str_repeat("lorem\n", 6);
?>

Only one item showing outside of foreach loop - PHP, Once I place the $comboClass outside of the foreach loop - I only get the can declare it before the foreach loop and assign it an empty string. This is a simple guide on how to loop through the characters of a string in PHP. First of all, you need to know about the function str_split. Basically, this function converts a given string into an array. i.e. The string is split up and each character is added as an element to an array.

You may use concatenating assignment operator, Please try the following code:

$lorem_text .= "lorem\n";
$lorem_outside_text = '';

for ($i = 0; $i <= 5; $i++) {
  $lorem_outside_text .= $lorem_text;
}

echo $lorem_outside_text;

For loop, For example, let's say I have the following code: if "calculateLoopLength" will keep giving back the same value, it can be moved outside the loop: A loop function that test for the string length at each iteration takes forever (possibly due to  Luckily for me, the ID was immediately followed by a non-numeric character, so I came up with a solution where I could loop through each character in the string and use each one for the required ID, but stop the loop when I hit the first character that was not a number.

You must append the text to the $lorem_text, not overwrite it. Type .= instead of =.

Personally, I'm usually adding text fragments to an array inside a loop, and then concatenate them using implode("\n", $lorem_parts).

foreach - Manual, In order to be able to directly modify array elements within the loop precede $​value "reference to value, which it doesn't have to copy each value when it loops". to the function, so PHP knows that it isn't allowed to modify the outside array, String keys of associative arrays, for which is_numeric() is true and which can  The author of the post wants the input element outside of the first loop for some reason. – Lexx Sep 10 '15 at 7:15 @Lexx btw you use a php tag inside a echo – jmattheis Sep 10 '15 at 7:16

Just use str_repeat, that will repeat the string however many times you want.

str_repeat($lorem_text, 5);

The List of the 10 Most Common Mistakes That PHP Developers , After going through the first foreach loop, $array remains unchanged but, as explained To still get the benefit of using references in foreach loops without running the risk of With that in mind, incrementing the string z in PHP yields aa : Outside of the class' scope, you can really only check if a null value will be returned,  for — loops through a block of code until the counter reaches a specified number. foreach — loops through a block of code for each element in an array. You will also learn how to loop through the values of array using foreach() loop at the end of this chapter. The foreach() loop work specifically with arrays.

Another option is to create an array in the loop that you later implode.

for ($i = 0; $i <= 5; $i++) {
  $lorem_text[] = "lorem";
}



echo implode("\n", $lorem_text);

Implode takes an array and uses the glue to make it string.

PHP Variables, The PHP echo statement is often used to output data to the screen. set in a strict sense, you can do things like adding a string to an integer without causing an error. A variable declared outside a function has a GLOBAL SCOPE and can only be You can have local variables with the same name in different functions,  The for loop - Loops through a block of code a specified number of times. The for loop is used when you know in advance how many times the script should run. test counter: Evaluated for each loop iteration. If it evaluates to TRUE, the loop continues. If it evaluates to FALSE, the loop ends. Create a loop that runs from 0 to 9.

Foreach loops in PHP: 6 facts you should know, In today's post I show you 6 facts that every PHP developer should know about foreach loops. Actually, each variable does have its own type, but it can change over time. Note that the second key is a numeric literal string. This means that variables defined outside the loop are also available inside it, and any variable  The first expression (expr1) is evaluated (executed) once unconditionally at the beginning of the loop. In the beginning of each iteration, expr2 is evaluated. If it evaluates to TRUE, the loop continues and the nested statement(s) are executed. If it evaluates to FALSE, the execution of the loop ends.

PHP - Loop Types, PHP - Loop Types - Loops in PHP are used to execute the same block of code a specified number of times. PHP supports following four loop types. The substr () function returns a part of a string. PHP 7.0 - If string = start (in characters long), it will return an empty string. Earlier versions returns FALSE. PHP 5.2.2 - 5.2.6 - If start has the position of a negative truncation, FALSE is returned. Other versions get the string from start. Using the start and length parameters with

Get excerpt using get_the_excerpt outside a loop, php and then call it from wherever. function get_excerpt_by_id($post_id){ $​the_post = get_post(  PHP supports C-style pre- and post-increment and decrement operators. Note: The increment/decrement operators only affect numbers and strings. Arrays, objects, booleans and resources are not affected. Decrementing NULL values has no effect too, but incrementing them results in 1. Increment/decrement Operators.

Comments
  • What do you mean by without changing $lorem_text?
  • Do you want both variables to contain the text five times? It looks like that's what you've tried to do, but I'm not sure why you think copying a string would change the original.
  • Add details about what you changed
