PHP $特殊字符转义

Question

I have this PHP script I am using to generate an iMacro script and I am unsure how to enter new lines and escape the '$' that is in the string which is a code from iMacro.

PHP keeps thinking that '$' is part of PHP in

"TAG POS=1 TYPE=DIV ATTR=ID:win0divUW_CO_JOBTITLE_HL$"

How can I do new line in PHP and get PHP to take the $ as a string.

<?php
error_reporting(-1);
ini_set('display_errors', 'On');

$file = 'datagenerated.txt';
$current = file_get_contents($file);


for ($x = 0; $x <= 4; $x++) {

for ($i = 0; $i <= 99; $i++) {
 $current.="TAG POS=1 TYPE=DIV ATTR=ID:win0divUW_CO_JOBTITLE_HL$" +$i+ " EXTRACT=TXT\n";
}
$current.="TAG POS=1 TYPE=IMG FORM=NAME:win0 ATTR=NAME:UW_CO_JOBRES_VW$hdown$img$0\n";

}

$current.="SAVEAS TYPE=EXTRACT FOLDER=C:\Users\Documents\iMacro FILE=Names.csv";

file_put_contents($file, $current);
?>

For some reason this is the output after escaping using \\$

Answer 1

Just escape the $ with the escape character \\ :

for ($x = 0; $x <= 4; $x++) {

for ($i = 0; $i <= 99; $i++) {
 $current.="TAG POS=1 TYPE=DIV ATTR=ID:win0divUW_CO_JOBTITLE_HL\$" .$i. " EXTRACT=TXT\n";
}
$current.="TAG POS=1 TYPE=IMG FORM=NAME:win0 ATTR=NAME:UW_CO_JOBRES_VW\$hdown\$img$0\n";

}

You could also use single quotes but then you would need to move your new line characters outside of the single quotes or else they would taken as a liter \\ and n :

for ($x = 0; $x <= 4; $x++) {

for ($i = 0; $i <= 99; $i++) {
 $current.='TAG POS=1 TYPE=DIV ATTR=ID:win0divUW_CO_JOBTITLE_HL$' .$i. ' EXTRACT=TXT'."\n";
}
$current.='TAG POS=1 TYPE=IMG FORM=NAME:win0 ATTR=NAME:UW_CO_JOBRES_VW$hdown$img$0'."\n";

}

Plus, I've noticed you're using +$i+ instead of concatenating .$i. which have been changed to reflect it.
