Question

I am using this

$lines = explode(PHP_EOL, trim($text));

to split $text into an array of lines so i can display like this:

foreach ($lines as $line) {
 echo $line;
}

but now i want to test the lenght of each $line and if lenght is over 50 chars i want to split each line in multiple of 50 chars.

How can i do this and keep all lines in the $lines array ?

I need a way to test each line or explode it using explode( wordwrap($line), 50 ); and then re-build the $lines array so i can cycle all lines again.

As I am not a coder I do not know how to insert new lines in the array if one line must be split in several pieces of 50 chars.

Hope you understand my question.
Thanks.

Answer 1

This is precisely what chunk_split is made for:

echo chunk_split( $line, 50 );

This’ll break your $line into multiple lines of 50 characters each.

Update after the OP specified that he wants to split the lines into individual elements in the array:

$temp = explode( PHP_EOL, trim($text) );
$lines = array();

foreach ($temp as $line) {
   $lines = array_merge( $lines, str_split($line, 50) );
}
