What should I do if I use the echo method in php to output long strings to a webpage to generate empty rows?

DutyList [2] = [new Array ("", "9"), new Array ("", "10 "), new Array ("class teacher", "11"), new Array ("Educational Administration", "12")];
DutyList [3] = [new Array ("", "1"), new Array ("", "2"), new Array ("consultant ", "3"), new Array ("Network Consulting

Consultant "," 4 "), new Array (" consulting assistant "," 5 "), new Array (" media specialist "," 6 "), new Array ("brand promotion specialist", "7"), new Array ("regional director", "8")];
As shown in the code above, I use php to dynamically generate js code. The short string output is okay. The long string dutyList [3] is output to the page and a blank line is generated, causing js to fail to run, thank you for your advice!

Answer:

It's not an ECHO problem. you have line breaks in your PHP code.
New Array ("Network Consulting

Consultant "," 4 "),
Here there is a line break in it. I usually use ECHO to output the entire webpage without any extra blank lines.
