How to execute multiline command in PHP?

Question

PHP

Good afternoon!

I have a team

convert 1.jpg -resize 700x \
\( -clone 0 -resize 720x1280^ -gravity center -extent 720x1280 -blur 0x8 -blur 0x8 \) \
+swap -gravity Center -compose over -composite \
1.jpg

in the console it works great. But when trying to execute it from PHP via exec(), shell_exec() etc. I get an error -

sh: 2: (: not found
sh: 3: +swap: not found
sh: 4: 1.jpg: not found

tell me how to "feed" this command from php?

It turns out that line breaks do not need to be escaped, but parentheses do.

convert 1.jpg -resize 700x \( -clone 0 -resize 720x1280^ -gravity center -extent 720x1280 -blur 0x8 -blur 0x8 \) +swap -gravity Center -compose over -composite 1.jpg
